Checking the encoder connection method and rotation direction
Before beginning master-follower operation, be sure to check the machine system travel direction and run command
direction for both the master side and follower side, the motor rotation direction, and the rotation direction with
encoder pulses.
If these are not set correctly, it will not be possible to perform operation correctly when performing master-follower
operation.

OPC-PGOPC-PG22
Fig. 5.3-45 Conveyor synchronization system configuration example
Refer to the instruction manual for PG interface card “OPC-PG”or “OPC-PG22” for details on how to install the PG
interface card in the inverter.
Connect the master side motor encoder output to terminal [XA], [XB], and [XZ], and connect the follower side motor
encoder output to terminal [YA], [YB], and [YZ].
The motor and encoder forward direction is rotation to the left (CCW) as viewed from the shaft. When rotating in
the forward direction (CCW), either connect so that encoder output pulses are forward rotation signals (B phase
leads A phase by 90°), or switch the A phase and B phase by switching the d14 and d59 setting values.
