 Trigger Signal Assignments for External Latches
The input signals in the following table are assigned to external latch trigger signals by default for
the OMRON 1S-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 on the Servo Drive.
The objects that must be set on the Servo Drive are listed in the following table.
