Cautions
● 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.

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).
<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.

7.3 Control of External Input and Output Voltages
(EXT VR: external; VR/DC 0 ~ 5V)
The adjustment of output voltage should be performed by making a connection with an external VR
or using a control voltage of 0 ~ 5V.
◆ External VR connection control: In the event of an external VR connection, voltage
adjustment on the OP panel is automatically disabled.
※As external control voltages higher than 5V may damage the controller, voltages lower than
5V must be applied.

7.4 4-channel Memory Selection Control (4_CH)
Operation modes can be changed by the data stored at the four memory channels (M1-CH ~ M4-CH)
according to external input control signals.
.Parameter setting ('PARA' Key):The "4ch-xx" should be set to "4ch-on." The 4CH LED should be
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.

The description of each error code and troubleshooting measures are as follows:
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
