Setting the Rotation Detection Level
Use the following parameter to set the speed detection level at which to output the /TGON sig-
nal.
•
Rotary Servomotors
•
Linear Servomotors
6.1.7
/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.
Note: 1. Use Pn50E = n.X
(/S-RDY (Servo Ready) Signal Allocation) to allocate the /S-RDY signal to another
connector pin. Refer to the following section for details.
6.1.2 Output Signal Allocations
2. Refer to the following section for information on the hard wire base block and the /S-RDY signal.
