3.7.7 Using Servo Ready Output Signal
This section describes how to wire and use photocoupler output signal /S-RDY (servo
ready).
“Servo ready” means that the SERVOPACK is not in servo alarm state when the main
circuit is turned ON. For absolute encoder specifications, “servo ready” means that, in
addition to the above, the SEN signal is at high level and the absolute encoder is also in
ready state.

This signal indicates that the SERVOPACK is ready to receive servo ON signals.
ON
status:
Circuit is closed or signal is at low level. Servo ready state
OFF
status:
Circuit is open or signal is at high level. Not in servo ready state
Use the following parameter to specify the pin to which the /S-RDY signal is to be output.

This parameter is used to specify a function signal as the 1CN output signal.
1s place Select the 1CN-25 and 1CN-26 (/COIN, /V-CMP) functions.
10s place Select the 1CN-27 and 1CN-28 (/TGON) functions.
100s place Select the 1CN-29 and 1CN-30 (/S-RDY) functions.
Example: /S-RDY is output to 1CN-29 and 1CN-30.
