6.1.6
/TGON (Rotation Detection) Signal
The /TGON signal indicates that the Servomotor is operating.
This signal is output when the shaft of the Servomotor rotates at the setting of Pn502 (Rotation
Detection Level) or faster or the setting of Pn581 (Zero Speed Level) or faster.
The /TGON signal is allocated to CN1-27 and CN1-28 by default.
Note: Use Pn50E = n.X (/TGON (Rotation Detection Output) Signal Allocation) to allocate the /TGON signal to
another connector pin. Refer to the following section for details.
6.1.2 Output Signal Allocations on page 6-6
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.
