/S-RDY (Servo Ready) Signal

The /S-RDY (Servo Ready) signal turns ON when the SERVOPACK is ready to accept the /S-
ON (Servo ON) input signal.
The /S-RDY signal is turned ON under the following conditions.
• Main circuit power supply is ON.
• There is no hard wire base block state.
• There are no alarms.
• If an absolute encoder is used, the SEN (Absolute Data Request) signal is ON (high level).
• If a Servomotor without a polarity sensor is used, polarity detection has been completed.
• If an absolute encoder is used, the SERVOPACK must be ready to accept the /S-ON (Servo
ON) signal and, if the SEN signal is ON (high level), the output of the position data from the
absolute encoder to the host controller must have been completed.
*
Do not include this condition if the /S-ON (Servo ON) signal is input for the first time after the control power supply
was turned ON. In that case, when the first /S-ON signal is input, polarity detection is started immediately and the
/S-RDY signal turns ON at the completion of polarity detection.
The /S-RDY signal is allocated to CN1-29 and CN1-30 by default.
