█ Other Notes

Input Power This series of inverters shall not be used to operate beyond the voltage range

specified in this manual. If necessary, please use a voltage boost or voltage drop device to

raise or lower the voltage below or above the requirements of this manual to the specified

voltage range.

Surge Protection This series of inverters are equipped with surge suppressors internally, which have

certain protection ability against induced lightning. However, for frequent lightning areas,

users need to put external surge suppressors in front of the power input end of the

inverters.

Usage of Contactor In the configuration of peripheral devices recommended in this manual, a contactor

should be installed between the power supply and the inverter. It is forbidden to use this

contactor as the start-stop control device of the inverter, because frequent charging and

discharging may affect the service life of its internal electrolytic capacitor.

When a contactor needs to be installed between the output end of the inverter and the

motor, it is necessary to ensure that the inverter is in a no-output state before the

contactor is put in/cut out, otherwise it may cause damage to the inverter.

Output Filter When the output of inverter is PWM high-frequency chopper voltage, add filter

devices between motor and inverter, such as output filter or output AC reactor, which can

effectively reduce noise output and avoid interfering with the normal operation of other

equipment in the system.

When the cable length between the inverter and the motor exceeds 100 meters, it is

recommended to choose the output AC reactor to avoid the inverter fault caused by the

over current generated by excessive distributed capacitance.Output filters are selected

according to field requirements.

Do not install phase shifting capacitor or surge absorber on the output side of inverter,

otherwise the inverter may burn down due to overheating.

SET360 User Manual

- 7 -

Motor Insulation The output of the inverter is PWM high-frequency chopper voltage, which contains a

large proportion of high-order harmonics. The noise, temperature rise and vibration of the

motor will be increased relative to the power-frequency voltage, especially the insulation

of the motor will be affected.Therefore, when the motor is used for the first time or stored

for a long time, insulation inspection is required. Normal use of the motor also need to do

regular insulation inspection, in order to avoid inverter damage caused by the motor

insulation. It is recommended to use 500V voltage tramegger, disconnect the motor and

inverter when do the inspection. Insulation resistance value should be higher than 5M Ω.

Derating The air at high altitudes area is thin, so the cooling effect of forced air cooling

inverters will be reduced. Electrolytes of electrolytic capacitors are also easy to volatilize,

affecting its life span. Accordingly, in the area of altitude above 1000 meters, the inverters

should be derated to use. It is recommended that the rated output current should be

reduced by 1% for every 100 meters of altitude.

valid. See figure 6-2 for details.

When DC brake starts, it usually used for fan and other stops when the load can

move.Because the load before the inverter outputs voltage, the motor is in free running state,

and the direction of operation is uncertain.Therefore, DC brake can be implemented before

starting, and then start the motor to prevent inverter failure.

enters into the DC braking time of the motor. DC braking is usually used for high-level parking or

positioning control.This parameter is zero, DC brake is invalid. See figure 6-3 for details.

This parameter is valid when F026 is set to 0. Please refer to F026, F031 and F039 for

relevant instructions.


F031 DC braking time 0.00～1.00 0.20

This parameter sets the DC braking current to be fed into the motor when starting and

stopping. Different braking current can be obtained by adjusting this parameter. When adjusting

the parameter, it must be gradually increased from small to large until sufficient braking torque

is obtained; otherwise, there is loss to the motor.

1.00（100%）current refers to motor rated current.


F039 DC braking starting frequency 0Hz～50.00Hz *

When the inverter decelerates and stops, the frequency decreases to the starting

frequency of DC braking, and the inverter starts DC braking stops.

When F030=0, DC braking is invalid when stops. When F030 is set to be valid, the inverter

stops with DC braking after the value is reduced to F039.


F041 Carrier frequency 0kHz～15kHz *

Carrier frequency has a certain relationship with electromagnetic noise of motor, and the

The higher the carrier frequency, the lower the electromagnetic noise of the motor, but the

stronger the interference to other systems, the greater the heat output of the inverter.When the

environment temperature is high and the motor load is heavy, the carrier frequency should be

reduced to improve the thermal characteristics of the inverter. Carrier frequency factory value is

set according to the machine type.


F042 Inching frequency 0.00Hz～320.0Hz 5.00Hz

This parameter can realize the inching function in test machine. Inching operation can be

realized through the digital quantity input terminals, inching frequency is limited by the

maximum frequency and lower frequency. When realizing inching function, other operating

instructions not to accept, inching frequency acceleration time is determined by the acceleration

time 4. After loosing the inching button, inverter output stops immediately and realizes the

inching function.Please set any of the corresponding six-way digital input terminals to 07 or 08.

The inching function is only valid when the machine is stopped, and it is invalid when the

machine is in operation.

6. Motor overheating

（1） If the load is too large and the actual torque has exceeded the rated torque of

the motor, it is suggested to increase the motor capacity.

（2） The environment temperature is too high. In a high temperature environment,

the electric machine burn out, please reduce the temperature around the motor.

（3） The voltage withstand between phases of the motor is insufficient. The

switching action of the inverter will cause shock wave between the windings of the

motor coils. Usually, the maximum impulse voltage will reach 3 times of the input

power of the inverter.

7. The inverter starts and interferes with other control devices

（1） Reduce the carrier frequency and the number of internal switching actions.

（2） Noise filter is set on the power input side and the output side of the inverter.

（3） Inverter and motor shall be properly grounded.

（4） Cover the cable with metal tube for shielding.

（5） Main circuit wiring and control line wiring respectively.

8. When the fan starts up, the inverter detects the loss speed

（1） When starting, the fan is idling. Please set the DC brake when starting.

（2） DC braking has been set when starting, please increase the DC braking value.

9. Machinery has a vibration or roar

（1） The vibration frequency of the mechanical system covibrates with the carrier,

and the carrier is adjusted to avoid the common vibration point.

（2） The vibration frequency of the mechanical system resonates with the output

frequency of the inverter.

（3） The vibration frequency of the mechanical system resonates with the output

frequency of the frequency converter.

Appendix One Standard Modbus Communication Protocol

1. Overview The SET360 series inverters support RTU mode in standard Modbus protocol.

Each byte (8bit) of data consists of two 4bit hexadecimal characters, such as 64H (hex).

Typical frame formats are as follows:

Start bit Mute: 3.5 characters interval

Subordinate machine address 1 byte

Modbus function number 1 byte

Data N byte

Check bit CRC16（2 bytes）

Address of inverter parameters: the communication address of inverter parameters is the

hexadecimal representation of the parameter number. For example, the communication

address of F100 is 0064H.

Communication specific variable. Including communication specific instruction variable and

communication specific state variable. The address starts from 0200H.

Storage of communication variable. Overwriting the inverter parameters (such as F100) is

saved in EEPROM, but it can't be overwritten frequently, otherwise it may damage the

EEPROM memory. Overwriting communication special variables (variables after 0200H) only

modify the value in RAM, and do not save after power off. Allow frequent overwriting without

damaging the memory.

Data type in communication. Because in communication, the data transmitted is a

hexadecimal integer. For the parameter value of the inverter, the minimum unit can be seen

from the decimal point position of the parameters in the function list. For example, the minimum

unit of F003 is 0.01hz.Therefore, according to Modbus protocol, communication transmission

3000 represents 30.00Hz.
