Operation after Zero Point Return Starts
Travel is started at the creep speed in the direction specified by the sign of the creep speed.
When the rising edge of the INPUT signal is detected, the positioning is performed at the positioning
speed.
When the positioning has been completed, a machine coordinate system is established with the final
position as the zero point.

The moving amount after the rising edge of the INPUT signal is detected is set in the Home Offset.
The positioning speed is set in the Speed Reference.

If an OT signal is detected during creep speed operation, an OT alarm will not occur, the direction
will be reversed, and a search will be made for the INPUT signal.

If an OT signal is detected during positioning speed operation, an OT alarm will occur.

The INPUT signal is allocated to the motion setting parameter OB

05B, allowing the zero point
return operation to be performed without actually wiring a signal. This method can thus be used to
temporarily set the zero point during trial operation.

Detecting the rising edge of the INPUT signal is performed using software processing. The posi-
tion where positioning is completed will depend on the high-speed scan setting, positioning speed,
etc. Do not use this method if repeat accuracy is required in the position where the zero point
return operation is completed.
* 1. The SERVOPACK P-OT signal.
* 2. The SERVOPACK N-OT signal.

The stopping method when the OT signal is detected depends on the setting of SERVO-
PACK parameters.
