Wiring the Control Input Signals for the Servo Drives

Wire the control input signals for the Servo Drive using the R88A-CN101C Control I/O connector (CN1).
For details on wiring, refer to the AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT Com-
munications User's Manual (Cat. No. I586).

*1 Control I/O Connector (CN1):
Used for command input signals, I/O signals, and as the safety device connector. The short-circuit wire is
installed on the safety signals before shipment.
Additional Information
• If you use the default Servo parameters, you must wire the immediate stop input, negative
drive prohibit input, and the positive drive prohibit input.
If these inputs are not wired, the CPU Unit will remain in the drive prohibit signal and emer-
gency stop signal detected state, and a minor fault level Controller error will occur. The minor
fault level Controller errors that will occur are an Immediate Stop Input Error and a Drive Prohi-
bition Input Error. (The event codes are 68220000 and 64E30000.)
• If the above signals are temporarily not wired while commissioning the system, you can tem-
porarily change the Servo parameters to prevent these errors from occurring in the CPU Unit.
Refer to A-1 Settings When Control Input Signals Are Not Wired for details on the settings that
you must change in this case.
