A-1 Connecting the 1S-series Servo
Drive
This appendix describes connections to an OMRON 1S-series Servo Drive with built-in EtherCAT com-
munications.
Servo Drives are connected using EtherCAT communications.
Refer to the NJ/NX-series CPU Unit Built-in EtherCAT Port Userās Manual (Cat. No. W505) for informa-
tion on the connection methods.
This section outlines the Servo Drive settings that are used when connected to OMRON 1S-series
Servo Drives with built-in EtherCAT communications (i.e., the applicable Servo Drives for the MC Func-
tion Module).
For details on the Servo Drives, refer to the AC Servomotors/Servo Drives 1S-series with Built-in Ether-
CAT Communications Userās Manual (Cat. No. I586).
The MC Function Module uses the general-purpose inputs of the Servo Drive for the following input sig-
nals.
ā¢ Immediate stop input
ā¢ Positive limit input
ā¢ Negative limit input
ā¢ Home proximity input
ā¢ External latch trigger signals (latch input 1 and latch input 2)
ļ¬ Assigning Positive Limit Inputs, Negative Limit Inputs, and Home Proximity
Input
The default settings of the input signals of an OMRON 1S-series Servo Drive are listed in the follow-
ing table.
*1 The signal name for the Servo Drive is the error stop input.
*2 The signal name for the Servo Drive is the positive drive prohibit input.
*3 The signal name for the Servo Drive is the negative drive prohibit input.
