High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• Mode 2: Forward/pulse train + Reverse pulse train
Note 1 To input a forward or reverse pulse train, the other pulse train input must be kept in a High state. When the
other pulse train input in a Low state, pulse train input will not be recognized because it is judged as
disconnected.
2 With the Position Control Unit (Model: CJ1W-NC3/CS1W-NC3), the inverter cannot establish
connection in Mode 2.
Use this function to set the gain for the position command or position feedback side. You can adjust the
main/sub motor rotation ratio, particularly for synchronous operation.

*2. It is recommended to start position control feedforward gain adjustment with P022 set to 2.00. To reduce the
position deviation between the main and sub motors, increase the feedforward gain. If motor hunting occurs,
reduce the feedforward gain.

Position Loop Gain
*3
*3. It is recommended to start position loop gain adjustment with P023 set to 2.00. To increase the positioning
accuracy and the holding power, increase the position loop gain. If the position loop gain is set too high and
causes hunting, decrease the position loop gain.
