This user constant is used to set the speed level at which the Servopack determines that
the motor is running and then outputs a signal.
The following signals are output when motor speed exceeds the preset value. (The circuit
between 1CN-27 and 1CN-28 is closed when motor speed exceeds the preset value.)
Signals are output when motor speed exceeds the preset value.

3.7.6 Using Servo Ready Output
1) 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.
Also, alarm state is reset at control power ON/OFF.
