ROBA-stop® brakes have outstanding benefits for operational security and easy maintenance.For nearly all applications the enclosed structionaldesign guarantees a high degree on functional securityof the brake without additional protective measurements.The high reliability increases the security and efficiencyof your complete machinery or equipment.The sensitive adjustment of the braking torque is especially important when an exact positioning is required or when drives must be adapted to alternative

manufacturing programmes. The production sequenceis optimised, its flexibility is brought to a maximum andquality is increased. The integral wear adjustment is anadditional distinguished feature. It minimises the risk ofadjusting errors, simplifies maintenance, saves timeand maintenance costs and decreases the downtime ofyour machinery.

ROBA-stop® Safety Brakes offer a complete selection of differentvariations. Nearly 30 years’ manufacturing and application experience with spring applied safety brakes and the knowledgeof multiple requirements in the electrical power transmissionfield are behind this programme. Perfected technology and continuous application specific development guarantee that asuitable brake is available for virtually every application.

ROBA-stop® Positioning Brakes offer exact positioning and highly repetitive accuracy even with high switching frequency.The braking torque can be set sensitively. This construction anddesign can accommodate most applications with a choice ofarmature discs.

ROBA-stop® Holding Brakes achieve very high braking torques. They are designed to hold large masses or loads without friction work. Braking from low speed with low frictionwork and corresponding application conditions can be allowed.

ROBA-stop® Tacho Brakes have a counterbore and tappedholes for attachment of a tachogenerator on the back face. Thesensitive braking torque adjustment allows exact positioningwith high repetitive accuracy.

ROBA-stop® Tacho-Peak Load Brakes correspond to theTacho Brake in function. Additionally they are equipped with anextremely strong armature disc which allows high friction work.

ROBA-stop® Peak Load Brakes are available in two furthervariations. Both are designed with extremely strong armaturediscs for high friction work. The design with open distance ringdissipates the braking heat to the environment. The unit withclosed distance ring is selected when high friction work is to beabsorbed and increased protection against outer influences isrequired.

ROBA-stop® Sealed Brake andROBA-stop®-S Brake corresponds to protection IP 67.They are completely sealed designs and corrosion resistant.

Mayr® Power Transmission have applied the highesttechnical and innovative standard for decades. Thefoundation for this success are the skills, productivityand quality consciousness of all Mayr® employees.The DIN ISO 9001 certification achieved confirms the high demands we set to experience, together with total our engineering integrity, and quality manufacturing processes. Mayr® Power Transmissionoffers you comprehensive depth of management toensure your confidence, and many year’s expertise,gained in both mechanical and electrical power transmission, confirms our position as leaders in thisfield.

FunctionROBA-stop® brakes are electromagnetic springapplied safety brakes. In a de-energised conditionthey are closed and correspond to the demandedsafety aspects, as for example if there is a power failure or an „emergency off“ condition.In a de-energised condition helical springs (11) pressagainst the armature disc (5). The friction linings (8) of the rotor (35) which is connected with the inputshaft via a gear hub (1) are held stationary betweenthis armature disc and corresponding mounting surface of the brake. If the coil (9) is energised amagnetic field is built-up which attracts the armaturedisc (5) to the coil carrier (2) and releases the rotor(35) with its friction linings (8). The brakes are releasedwith applied voltage.

Hoist and travelling drives of the narrow aisle materialshandling system are equipped with ROBA-stop®

brakes. The ROBA-stop® Positioning Brake at the rearof the travel motor brakes the drive from a slow speedexactly to the required position. The ROBA-stop®

Peak Load Brake on the hoist motor undertakes thesame function during the standard operation – brakingand positioning from a slow speed. In case of emergency-off or power failure, this brake can brakesafely from high speeds and with a downward movingload. It is capable of absorbing high friction work anddissipating the heat to the environment very rapidly.

Manufacturer’s declarationROBA-stop® brakes as well as rectifiers, phase demodulators, ROBA®-switch, spark quenching unitsand power supply units are not machines within thescope of the Machinery directive 98/37/EG, but components for installation into machines. An initialstart up is prohibited until it has been noticed that themachinery or the equipment into which this product hasbeen incorporated correspond to the EG-guide lines.

ROBA-stop® brakes are developed and manufacturedin conformance with the national standard DIN VDE0580 according to the low-voltage directives73/23/EWG. The observance of the relevant EMV-guide line 89/336/EWG is to be guaranteed.

Safety regulationsAttention!Hazardous conditions when contacting hotconnections and components.Danger, if the spring applied brake is used in an

improper way,if the spring applied brake has beenmodified or reconverted,if the relevant standards of the safety orinstallation conditions are not observed.

Only qualified and well-trained specialistsshould work on the units to avoid any personal injury or damage to machinery.

Attention!The installation and operating instructions mustbe read carefully and all safety regulationsobserved before installation and initial operationas danger to personnel and damage to machinerymay be caused.Spring applied brakes are developed and manufactured in conformance with the temporallyknown rules of the technology and they arebasically considered as fail-safe at the time ofdelivery.Spring applied brakes are not suitable for theapplication in potentially explosive or aggressiveatmospheres.

Observe!– Only qualified well-trained specialists which are familiar with

transportation, installation, initial operation, maintenance and operating of the units as well as with relevant standards may carryout the corresponding work.

– Technical data and indications (Type tag and documentation) are tobe kept in any case.

– Supply connection according to Type tag.

– Assembly, maintenance or repair must not be made when theunit is energised.

– Electrical leads must not be under tension when connected.

– Check current carrying components regarding damage beforeinitial operation. They must not be in contact with water.

– If the friction lining and the friction surface come in contact withoil or grease there ia a loss of the braking torque.

With these safety regulations no claim on completeness is raised!

Necessary protective measures to be undertakenby the user:– Cover all moving parts to prevent personnel injury as squeezing

and seizing.

– Cover dangerously hot magnetic parts to prevent contact.

– Attach a conductive connection between magnetic part and electrical conductor (PE) of the fixed installation (protection class I)to prevent electrical shock.

– Install spark quenching units to prevent high inductive cut-off peaks.

Note to electromagnetic compatibilityImportant

There are no emissions from the listed single components withinthe meaning of EMV guideline 89/336/EMG. However, increasedinterference levels can occur when working components are operatedoutside their specification limits as for example, energising the brakewith rectifiers, phase demodulators or ROBA®-switch in the lineside.Therefore, the installation and operating instructions must be readcarefully and the EMV guidelines are to be observed.

Standards and InstructionsROBA-stop® brakes are developed and manufactured in conformancewith the national standard DIN VDE 0580 according to the low-voltage directive 73/23/EWG.

Following directives have been used:98/37/EG Machinery directive73/23/EWG Low-voltage directive89/336/EWG EMV-guideline

Protection class I The protection is not only based on thebasis isolation, but that all conductive components must beconnected with the protective conductorof the fixed installation. In case the basisisolation fails, no contact voltage canremain existing. (EN 50144-1, 11.99,classification VDE 0740-1)

Protection IP 54 Dustproof and protection againstcontact and splash water from all directions (DIN EN 60529)

Ambient temperature -20 °C up to +40 °CAttention!The torque could be severely reduced in case of temperatures over orunder the freezing point due to thawing.The user must provide correspondingcounter measures.

Conditions of the unitImportantThe catalogue values are for reference only, and may vary in certaincases. When selecting the brake, site of installation, braking torquefluctuations, permissible friction work, behaviour during run-in,wear and ambient conditions are to be carefully checked and agreed with the unit manufacturer.

Observe!– The mounting and connecting dimensions at the site of

installation must match to the size of the brake.– ROBA-stop® brakes are designed for a relative continuous

operation.– ROBA-stop® disk brakes are designed for a dry running only.

Attention!Should oil, grease, water or similar materials come in contact withthe friction surfaces the braking torque could be reduced.– The braking torque depends on the corresponding

running-in condition of the brake.– Protective system for damping of overvoltages, as high

inductive voltage peaks occur when the brake is switched off onthe DC side which can result in damage to the coil isolation aswell in the burning away of the switching contact in extremecases.

– Provide additional necessary safety measures against corrosions of the brake if they are used in extreme ambientconditions or in the open with direct atmospheric influences. The metallic surface of the brake is protected against corrosionarranged by the factory.

– The connecting cables or leads have a silicone coating which hasa limited resistance to chemical attack. The place of operationand the suitability must be checked.

powertransmission

Design Page

ROBA-stop® BrakeSize 2Compact design with a central coil spring and friction lining rotor. Hand release and flange plate are available as additionalcomponents. For braking torques up to 1,5 Nm.

ROBA-stop® Positioning BrakeFor braking and exact positioning. Consistent of repetitive accuracy even with high switching frequencies. The brake torquecan also be sensitively adjusted via pressure screws. Most application requirements can be met by means of different armature discs.

ROBA-stop® Holding BrakeThe Holding Brake achieves a higher brake torque than the Positioning Brake due to additional coil springs. The Holding Brake is suitable for holding masses or loads without friction work.Braking from a low speed with low friction work is possible undercertain conditions (please enquire). It operates most favourablywith the fast acting rectifier „ROBA®-switch“ (see page 32).

ROBA-stop® Tacho BrakeThe Tacho Brake has a fixed distance ring and on the back face of the coil carrier, a spigot and three tapped holes. The spigot isconcentric with the outer diameter of the distance ring. This enables tachogenerators to be easily fitted to the brake via the spigot and tapped holes.

ROBA-stop® Peak Load BrakeFriction heat which may occur is dissipated by a thicker armaturedisc and an open graduated distance/adjusting ring. The PeakLoad Brake can absorb very high friction work, for example,during an emergency stop. In a normal switching operation it operates as a Positioning Brake.

ROBA-stop® Peak Load Brake with solid distance/adjusting ringDue to the special armature disc the Peak Load Brake can absorbvery high friction work, for example, during an emergency stop. Ina normal switching operation it operates as a Positioning Brake.The solid distance/adjusting ring guarantees safe protectionagainst outside influences together with good heat dissipation.

ROBA-stop® Tacho Peak Load BrakeThe Tacho Peak Load Brake can absorb high friction work, for example with an „emergency off“ condition due to a specialarmature disc, the solid distance ring enabling the existing heatto be dissipated. Due to a recess and three tapped holes on theback face of the coil carrier, the tachogenerator can easily befitted and accurately mounted.

ROBA-stop® Sealed Brake Sizes 3 ÷ 6This design is completely enclosed by an one-piece cover. The sealed enclosure corresponds to IP 67 protection.

ROBA-stop®-S Brake Sizes 8 ÷ 10Protected against corrosion, sealed design for extreme environmental conditions. Corresponds to IP 67 protection.

The Tacho Brake has a fixed housing, a spigot and three tapped holes on theback face of the coil carrier. The recess is concentric with the outer diameterof the housing and coil carrier.

The tachogenerator requires an intermediate flange, which has to bemanufactured according to the corresponding dimensions of the brake andthe tachogenerator flange.

The generator has to be selected by the customer. Among other things, theoperating speed, the thermal limiting current of the generator and theelectrical data of the connected evaluation and control units are decisive for the selection.

The brake can easily be connected to D C voltage via our comprehensiverange of electrical accessories (see page 26).

powertransmission

ROBA-stop®S Brakes have two functions. During standard operation they work as holding brakes. Whenthe drives have been switched off the brakes hold the equipment safely in position.During critical operational situations, e.g. with emergency-off or power failure, ROBA-stop®-S Brakes aredesigned to absorb peak loads with high friction work. These brakes are designed for vertical and horizontal operations.

Dust and waterproofCompletely enclosed design of the brake corresponds to IP 67protection.

Permanent protection against corrosion:IP 67 protection, a high-quality primary coat of the brake body,chrome or nickel coated interiorparts or a rustproof steel manufacturing assure sustainableprotection against corrosion.

Easy handlingCompact construction and smallouter diameters provide an easyhandling of the brakes.

Inspection without standstill of equipmentOne hole allows fast inspection of the air gap without dismantlingthe brake or stoppage of theequipment.

Minimum maintenanceexpenditureIn case the friction linings are worn only the air gap must bereset or the rotor with the frictionlinings must be exchanged respectively.

Minimum operatingexpensesHigh working reliability and lessmaintenance expenditure reducethe operating expenses of the brake to a minimum.

RectifierA rectifier integrated in the terminalbox allows a brake connection toAC-supply. The magnetic coil isdesigned as DC-coil.

Wear controlAn additional micro switch can beinstalled into the ROBA-stop®-SBrake which monitors the wear ofthe friction linings.

Brake housing and integral terminal box The one-piece cast iron housingwith integrated terminal box isextremely robust and, therefore,protected against mechanicaldamages.

Anti-condensation heatingThe heater avoids condensationwater inside the brake. This usageis especially recommended with temperatures under zerodegree Celsius or in case of high airhumidity.

Braking torqueBy changing the number of springsthe brake torque can be adapted tocustomer’s requirements.

Optimum protection forelectrical equipmentThe electrical supply and the microswitch of the inspection and monitor functions are completelyprotected inside of the cast terminal box.

Release monitoringThe ROBA-stop® S Brake is fittedwitha micro switch for release monitoring.The micro switch supplies a signal ifthe brake is opened.

Tacho attachmentThe brake body has a possibility fora tacho attachment. If no tacho isused, the coil carrier is closed by a cover.

Emergency hand releaseThe ROBA-stop®-S Brake is fitted with an emergency hand release.The brake can be released mechanically via two screws.

Condensation water inspectionA regular inspection is possible viaa drain plug.

Motors with self-ventilationIn order to assemble the ROBA-stop®-S Brake onto motorswith through-going shafts at the B-bearing side, the closed standard-cover at the brake back side isexchanged against the open coverwith integrated radial shaft seal ring.

Fitting the brakeAssembly conditionsThe eccentricity of the shaft end against the fixing hole p.c.d. mustnot exceed 0,2 mm (with brake sizes 3 - 6), with larger brakes itmust not exceed 0,4 mm.

The deviation in the true running of the screw-on surface to theshaft must not exceed the permissible true running toleranceaccording to DIN 42955.

Larger deviations can cause a reduction in torque, a continuouswear of the rotor and overheating.

Rotor (35) and braking surfaces must be free of oil and grease.

There has to be a suitable counter friction surface for rotor (35)made from steel or cast iron. Sharp-edged interruptions of the friction surface have to be avoided.

If no suitable friction face is available, our flange plate (29, Fig. 2bottom half) can be used.

InstallationROBA-stop® brakes are known to be easily installed:

The hub (1) is mounted onto the shaft and is located axially (by means of a snap ring for example). Recommended key withhub-shaft connection = k6/H7. Fitting of the hub to the shaft withthe bore being tight may cause a binding of the rotor on the huband a trouble-free function is not possible. After the rotor (35) hasbeen pushed onto the hub (1), the brake just needs to be securedat the B-bearing housing of the motor or on the machine wall bymounting screws (13). These screws (13) are to be tightened to thetightening torque Ma (according to table 1). The assembly can be invertical or horizontal mounting positions.

In case of the design with assembled cover plate (30) the brake iscompletely closed and corresponds to protection IP 54.

Brake torqueDefinitionThe braking torque indicated in the technical data is the switchingtorque measured with mean friction radius and circumferentialspeed of v = 1,0 m/sec.

For the different applications of the brake it is to be considered thatthe brake torque deviations can arise of up to +40/-20% (pleasecontact the works, if necessary).

The load moment existing at the machine should be max. 50% ofthe indicated brake torque.

AdjustmentThe rated torque indicated in the technical data for the ROBA-stop® brakes are set at the factory. The brake torque may be reduced by turning the setscrews (14) to the left and may beincreased by turning them to the right. When adjusting the braketorque all setscrews (14) must be uniformly adjusted.

Helical springs (11) must be removed out of the brake, if the braketorque requires considerable reduction. In this case the springs (11)still remaining in the brake should be distributed so that the load onthe armature disc (5) is evenly distributed.

Please contact the works for the corresponding adjusting diagrams, if you would like to change the brake torque.

Fitting the hand releaseThe hand release is fitted and adjusted according to the instruction.

When adjusting the lock nuts (21) please notice the following:

The restoring bolts (17) limit the stroke of the armature disc (5) inbraking direction. They may only be tightened by the lock nuts sothat the armature disc (5) can carry out the stroke „X“ according totable 1 and figure 2 (detail).

Table 2

Adjusting the air gapAs the rotor friction material (35) wears down, the air gap„a“ increases. The rated air gap can be restored by turningthe graduated distance ring (31). One graduation = 0,05 mm.The fixing screws (13) and the lock washer (58) are loosened, the graduated distance ring (31) is rotated counter-clockwise to equal the wear (view to rear side of thebrake). Afterwards, the fixing screws (13) and lock washer(58) must be tightened. This adjustment can be repeateduntil the graduated distance ring (31) contacts the rod-stopof the coil carrier (2).

Switching timesThe switching times of the brakes are influenced by thetemperature, the different methods of spark quenching orthe air gap between the armature disc and the coil carrierdepending on the wear condition of the linings.The values given in Table 2 are mean values which refer tothe nominal air gap with warm brake.

Fig. 3

MaintenanceAt specific intervals the air gap between armature disc andcoil carrier must be checked and adjusted. When the rotorhas reached the max. permissible degree of wear, it has tobe exchanged. You have to take care when exchanging thatthe friction faces and brake linings are free of oil andgrease.The brake does not require any other maintenance.

The terminal box with terminal serves as the interface forthe supply line.The DC voltage is connected to a terminal with twochannels; for the Peak Load Brake, four additionalterminal points are possible for wear and temperaturemonitoring.

Standard design; the brakes are available with cable asstandard, which has a DC voltage circuit.Special DC voltages are possible on request.

Easiest and most economic method of connecting abrake, if 230 V~ or 400 V~ are available. Compact unitbetween mechanical brake and fitted electronics.

Further possibility to operate the brake on 230 V~.The advantage lies in the favourable temperature behaviour of the coil in comparison with the half-waverectifier. Compact unit between mechanical brake andfitted electronics.

The ROBA-switch has an internal switching betweenbridge connection and half wave rectification. Theoutput voltage halves itself after a period which canbe selected. The ROBA-switch is used for fast switchingor to reduce the power consumption of clutch and brakecoils.

The spark quenching consists of one terminal, one varistor and one protective recovery diode.The spark quenching limits spikes, which occur whenswitching off the brake on the DC voltage side andthereby protects the switching contact from consumption.

If low voltage protection is required, we recommend the power supply.This additional unit converts 230 V~ into 24 V~.The power supply is not fitted on the brake.

Same application as the terminal box with half-waverectifier. The half-wave rectifier can separately befitted, either in the switch cabinet or, for examplein the motor`s terminal box . The price for this version is lower since the terminal boxis excluded.

Same application as the terminal box with bridge connected rectifier.The bridge connected rectifier can separately befitted, either in the switch cabinet or, for example, in the motor`s terminal box. The price for this version is lower since the terminal box is excluded.

Switching behaviourBuild-up of the magnetic fieldWhen switching on the voltage a magnetic field in the brake coil isbuilt-up and the armature disc is attracted to the coil carrier by thesame; the brake releases.

Field build-up with standard excitation:When rated voltage is applied to a brake field coil, the coil currentdoes not achieve its nominal value immediately. The inductivity of thecoil effects that the current slowly rises in the form of an exponentialcurve. The build-up of the magnetic field and, therefore, the torquerise also ensures delay accordingly (Fig. 1, curve 1).

Field build-up with overexcitation:A fast drop fo the brake torque can be achieved, if a higher voltagethan the rated voltage is applied to the coil for a short time. Herewiththe current rises faster. When the brake has released you can switchover to the rated voltage (Fig. 1, curve 2). The interrelationship between overexcitation and switching time is approximately proportional up to 4 times the rated voltage, i.e. doubling the ratedvoltage, halves the switching time for releasing the brake.The ROBA®-switch fast acting rectifier uses this behaviour for 104 V-coils (see page 32) as well as the phase demodulator (see page 31).

Reducing the magnetic fieldAC voltage switching:The circuit of the magnetic coil is interrupted in front of the rectifier (Fig. 2), i.e. in the mains side.When switching off the coil voltage, the magnetic field effects thatthe coil current conducts further via the rectifier diodes and onlydrops very slowly. The magnetic field reduces itself slowly andeffects that the brake torque slowly rises (Fig. 4; curve 1).An AC voltage switching should be carried out, if switch-off timesare insignificant. An AC voltage switching does not require anyprotective arrangements for coil or switching contacts as the rectifier diodes act as recovery diodes when switching off.

Fig. 2

DC voltage switching:The coil current is interrupted between rectifier and coil (Fig. 3).The magnetic field reduces itself quickly — fast rise of the braketorque. In case of DC voltage spikes are generated in the coil, whichlead to a very quick wear of the switching semiconductors.The switching contact has to be protected against consumption.

Fig. 3

Protective wiringProtective arrangements are necessary to protect the coil againsthigh spikes and to protect the switching.

Protective wiring:1. Recovery diode parallel to the coil — yields the same switching

times as the AC voltage switching (Fig. 4, curve 1).2. Adapted varistor parallel to the coil — simple adaption, good

protection, fast reducing of the magnetic field with defined switching-off voltage (Fig. 4, curve 2).

To achieve both items it is the best to use Mayr Power Transmissionspark quenching units (see page 33).

Phase demodulator

®

powertransmission

Manufacturing declarationThe phase demodulator corresponds to theregulation of low voltage directives73/23/EWG. The safety regulations(page 5) are to be observed.

Application

• Fast switching of 104 VDC-coils, reducing to52 VDC-coils-holding voltage.Advantage: reducing of the coil temperature

• AC voltage ON and OFF switchings of the coil withshortest attraction and releasing times.

• Fitted spark quenchings for the switch contact.

Function

The phase demodulator is provided for an operation at UAC-230 VACor 400 VAC supply voltages. During “ON-switching” of thesupply voltage the coil is energised with overexcitation voltages of 190 VDC or 330 VDC.When the overexcitation time has passed the unit switches thecoil to a holding voltage of 52 VDC or 104 VDC. During “OFF-switching” the coil is de-energised.The ON and OFF switching is always alternating.Shortest switch-OFF times are achieved using a fitted electronic protective relay.
