/S-RDY (Servo Ready) Signal

The /S-RDY (Servo Ready) signal turns ON when the SERVOPACK is ready to accept the
SV_ON (Servo ON) command.
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 SENS_ON (Turn ON Sensor) command has been input.
• If a Servomotor without a polarity sensor is used, polarity detection has been completed.
• If an absolute encoder is used, the output of the position data from the absolute encoder to
the host controller must have been completed if the SENS_ON (Turn ON Sensor) command is
being input.
*
Do not include this condition if the SV_ON (Servo ON) command is input for the first time after the control power
supply was turned ON. In that case, when the first SV_ON command is input, polarity detection is started imme-
diately and the /S-RDY signal turns ON at the completion of polarity detection.
Type Signal
Output /S-RDY Must be allocated.
Note: 1. You must allocate the /S-RDY signal to use it. Use Pn50E = n.X (/S-RDY (Servo Ready) Signal Allo-
cation) to allocate the signal to a connector pin. Refer to the following section for details.
6.1.2 Output Signal Allocations on page 6-6
2. Refer to the following section for information on the hard wire base block and the /S-RDY signal.
