Zero Point Return Input
Signal

This signal must be turned ON by using the ladder program.

Speed Reference
Setting

Set the positioning speed to use after detecting a phase-C pulse. The sign is
ignored.
The travel direction will depend on the sign of the Zero Point Return Travel
Distance.
Setting to 0 or a negative value will result in an error.

Override

This parameter allows the travel speed to be changed without changing the
Speed Reference Setting (OL

10). The setting can be changed during

operation.
Setting range: 0 to 32767 (0 to 327.67%)
Setting unit: 1 = 0.01%

Zero Point Return
Method

18: INPUT & Phase-C Pulse Method

Approach Speed

Set the speed to be used at zero point return start.
The travel direction depends on the sign of the approach speed.
Setting to 0 will result in an error.

Creep Rate

Set the speed and travel direction (sign) after the INPUT signal is detected.
Setting to 0 will result in an error.

Zero Point Return Travel
Distance

Set the travel distance from the point where a phase-C pulse is detected.
The travel direction will depend on the sign.
