z The types of zero point return operations vary in accordance with the series of machine
controller.
For the MP900-series: Fixed parameter 31 (Zero Point Return Method)
For the MP2000-series: Setting parameter OWxx3C (Zero Point Return Method)
„ Types of Zero Point Return Operation
The details of zero point return method are as explained below.
DEC1 + Phase-C pulse: Parameter setting 0
The zero return operation is executed while switching the feed speed in three steps.
ZERO signal: Parameter setting 1
The zero point return operation is executed by sending the ZERO signal instead of the
phase-C pulse in the “Phase-C pulse” method of the zero point return.
DEC1 + ZERO signal: Parameter setting 2
The zero point return operation is executed by sending the ZERO signal instead of the
phase-C pulse in the “DEC1 + Phase-C pulse” method of the zero point return.
