5.5.6 Using the Servo Ready Output Signal (/S-RDY)
The basic use and wiring procedures for the Servo Ready (/S-RDY) output signal
(photocoupler output signal) are described below.
Servo Ready means there are no servo alarms and the main circuit power supply is
turned ON. An added condition with absolute encoder specifications is that the SEN
signal is at high level and absolute data was output to the host controller.
This signal indicates that the servo amplifier has completed all preparations and is
ready to receive the Servo ON signal.
The following parameter setting is used to change the CN1 connector terminal that
outputs the /S-RDY signal.
The parameter is factory set so the /V-CMP signal is output between CN1-29 and 30.
See 5.3.4 Output Circuit Signal Allocation for more details on parameter Pn50E.
