Trigger Signal Assignments for External Latches
The input signals in the following table are assigned to external latch trigger signals by default for the
G5-series Servo Drive.
*1 The signal name for the Servo Drive is the external latch input 1.
*2 The signal name for the Servo Drive is the external latch input 2.
The MC Function Module does not perform backlash compensation.
If you require backlash compensation, use the compensation function of the Servo Drive.
The objects that must be set on the Servo Drive are listed in the following table.
Refer to the G5-series AC Servomotors/Servo Drives with Built-in EtherCAT Communications User’s
Manual (Cat. No. I576) for details on backlash compensation.
