Wiring the Control Input Signals for the Servo Drives

Wire the control input signals for the Servo Drives as shown in the following figure.

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 detect drive prohibit and immediate stop sig-
nals, and a minor fault level Controller error will occur. The minor fault level Controller errors
that occur are as follows: Immediate Stop Input Error, Positive Limit Input Detected, and Nega-
tive Limit Input Detected. (The event codes are 64E20000, 644A0000, and 644B0000, respec-
tively.)
• 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.
