1. The travel distance after the phase-C pulse is detected is the value of the Zero Point
Return Travel Distance parameter. The positioning speed is the value of the Speed
Reference Setting parameter.
2. If an overtravel signal is detected during motion at the approach speed, an overtravel
alarm will not occur. The direction will be reversed, and a search will be performed for
the HOME signal.
3. If an overtravel signal is detected when the axis is moving at the positioning speed, an
overtravel alarm will occur.
4. The stop method when an overtravel signal is detected depends on the SERVOPACK
parameter settings.

Set the positioning speed to use after the phase-C pulse is
detected. The sign is ignored.
The travel direction depends on the sign of the Zero Point
Return Travel Distance parameter.
Set the speed at which to begin the origin return operation.
The travel direction depends on the sign of the approach
speed.
Set the speed and direction (based on the sign) after the HOME
signal is detected.
