● This product can only be applied to piezoelectric-type parts feeders.
● Do not use this product in a place exposed to explosive or flammable materials.
Otherwise, there is a risk of fire or explosion.
● Do not use this product in dusty or humid places.
This is neither a waterproof nor dust-proof product. Especially, an extra dust-protection
measure is required in a place exposed to large amounts of metallic dust.
● Do not turn on and off the input power switch frequently.
Otherwise, unexpected troubles may occur due to rapid heat deterioration of the internal
electronic components.
In particular, never use an electronic relay for switching the input power of this
product for the purpose of controlling on/off operations of the parts feeder (the EXTON
terminal must be used for controlling external signals).
● Do not perform on/off operations on the output side .
No electronic relay should be used to operate or shutdown the driving parts on the output
side in order to avoid any damage to the controller (the EXTON terminal must be used for
controlling external signals) .
● Do not apply welding processing work to the feeder when the driving parts are connected
with the controller.
The current leaking from welding work may damage the controller.
● Do not use the output of a PWM inverter as input power for this product.
This may damage the product.
● The input and output power must remain within the range of the rated current and voltage.
● Do not disassemble, repair, or alter the product in an inappropriate manner.
This may damage the product or cause malfunction.
● Wiring work should be performed after disconnecting the power supply.
Otherwise, the product may be damaged or the operator may be exposed to the risk of an
electric shock.
● The grounding terminal of the input and output power must be grounded.
This reduces electrical noise and the risk of an electric shock in the event of a short
circuit.

<Cautions>
1.Be sure to disconnect the input power prior to removing the cover.
2.The grounds (FG: frame ground) of the input and output power terminals must be grounded in
order to prevent electric shocks or to guarantee stable operation.
Stable operation of constant amplitude/auto tuning functions -- especially, triggered by the
feedback sensor (vibration sensor)--will not be guaranteed, if the grounds are not grounded.
3.Operation must be performed with the cover closed.
The connecting procedure for the connector is as follows:
① Input and output power, including other necessary accessory devices, should be connected
with the product in reference to the figure below.
② The setting of the overflow sensor (NPN/PNP) should be performed after opening the cover on
the right side.
This product can be used without any mechanical or electrical settings regarding the input
power as it supports a wide range of operating voltages (100V ~ 240V AC).

Pressing the FBK key for more than 3 seconds triggers a warning
beep and the FBK LED continues to remain turned on or off (disabled)
or flashes (enabled) repeatedly.
◆ When the constant amplitude operation function is disabled:
The 'FBK' LED will be turned off.
.Although the FB sensor is connected with the system, but the
constant amplitude operation function is disabled
◆ When the constant amplitude operation function is enabled:
The FBK LED will be turned on or blink.
.The constant amplitude operation function has been activated.
※ This function is only available when a FB sensor is connected with the system
(refer to page 17).
If the system is not connected with a FB sensor, the FBK LED remains turned on.
※ If the operation of the system is performed without mounting a vibration sensor on the
vibrator (albeit the sensor is connected with the controller), the constant amplitude
operation function must be "disabled."

1.Select an optimal voltage level for the vibrator to
generate vibration in consideration of its specifications
after entering Voltage Setting mode by pressing the SET/VF key.
2.'Enter Frequency Setting mode by pressing the SET/VF key
again, and then press the RUN key in order to enter RUN
mode at a frequency of 400 Hz.
3.Find a point of the strongest vibration at a constant voltage,
while lowering the frequencies.
.More than two vibration points can be found. If this is the
case, choose the strongest vibration point.
.If vibration is too strong, reduce the voltage and
then find the strongest vibration point.
※ The frequency at which maximum vibrationoccurs at a constant voltage is the resonancefrequency.
4.Manual Adjustment of Resonance Points
This section explains how to find resonance frequencies manually when the system is either
connected or disconnected with a FB sensor.

4. If the strongest vibration point is found by changing frequencies at a constant voltage,
calibrate the vibration to obtain an optimal amount of vibration.
※ As large fluctuations in vibration may occur at the resonance point, a frequency higher
than the resonance point should be selected if the constant amplitude function is not
working.

turned on (the factory default setting is '4ch-oFF')
.All parameters stored in the selected channel, such as voltages, frequencies, etc., are
replaced by the current operating values.
.Frequencies and all other parameters, except for voltages, should be identical prior to
saving them to each channel, if only changes in speed can be controlled.
.The channel number selected on the screen is briefly displayed as "CH-Ox" whenever there is
a change in operation modes.
In this mode, the use of an external VR is automatically disabled.

7.5 Operation Synchronization Output Signals (SYNC)
The contact point signals corresponding to the operation and shutdown status of the controller
is printed.
.Used for interlocking the hopper with the bowl feeder.
7.6 Constant Amplitude Sensor Connection (FBSN)
Connecting a vibration sensor with the FBSN connector automatically activates the constant
amplitude function.
To intentionally disable this function, refer to "Enabling and Disabling of Constant Amplitude
Operation Function (FBK)" on page 10 hereof.

Error code Cause Recommended solution
Err01 □ EEPROM write error
.EEPROM write error.Requires repairs
Err03
□ Overheating or overcurrent
.The internal heat sink is
overheated
.A current exceeding the rated
amperage capacity flows
.Turn off the power and remove the cause of
overheating, and then use the system after
sufficiently cooling the system by natural
cooling
.Turn off the power and remove the cause of
overcurrent before use
Err05□ A hugely erroneous feedback
sensor level
.The vibration of the FB sensor
is too strong
.The sensor output levels should be adjusted
by changing the position or direction of
the FB sensor
10.Protection functions and alarms
The protective functions of this product is activated in the event of an error due to a user's
