A-1 Connecting the Servo Drive
This appendix describes connections to an OMRON G5-series Servo Drive with Built-in EtherCAT
Communications.
Servo Drives are connected using EtherCAT communications.
Refer to the
NJ-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No. W505) for information
on the connection methods.
This section outlines the Servo Drive settings that are used when connected to OMRON G5-series
Servo Drives with Built-in EtherCAT Communications (i.e., the applicable Servo Drives for the MC Func-
tion Module). Refer to the
G5-series AC Servomotors/Servo Drives with Built-in EtherCAT Communica-
tions User’s Manual (Cat. No. I576) for details on the Servo Drives.
All of the functions of the MC Function Module can be used for Servo Drives with the unit versions that
are given in the following table.
Additional Information
• You can also use unit versions of the OMRON G5-series Servo Drives with Built-in EtherCAT
Communications other than the recommended unit versions.
• The R88D-KN
@@@
-ECT-R (unit version 1.0) Servo Drives support only position control (Cyclic
Synchronous Position Control Mode). You can use them for applications that do not require
velocity control (Cyclic Synchronous Velocity Control Mode) or torque control (Cyclic Synchro-
nous Torque Control Mode).
Refer to the
G5-series AC Servomotors/Servo Drives with Built-in EtherCAT Communications
User’s Manual (Cat. No. I573) for details on functions.
• When you use an OMRON G5-series Servo Drive with unit version 2.0 or earlier, do not set the
node address switches to 00. If you set them to 00, a network configuration error occurs.
• Refer to the G5-series AC Servomotors/Servo Drives with Built-in EtherCAT Communications
User’s Manual (Cat. No. I576) for details on the differences between the unit versions of the
OMRON G5-series Servo Drives.
The MC Function Module uses the following input signals of the Servo Drives.
• Immediate stop input
• Positive limit input
• Negative limit input
• Home proximity input
• External latch trigger signals (latch input 1 and latch input 2)
