[Encoder Z-phase mask amount]
When the stop position is near the encoder Z-phase by the dispersion, the Z-phase position to be the home
position can be fixed by setting encoder Z-phase mask amount.
1) When stop position is before the encoder Z-phase
Mask encoder Z-phase in this section.

2) When stop position is after the encoder Z-phase

Note1. When the stop position disperses largely, the home position may change by one revolution of the motor even when
encoder Z-phase mask amount is set. In this case, adjust command speed to reduce the dispersion.
2. When the following conditions are satisfied in the calculation of Z-phase mask amount, Z-phase mask amount
setting error (operation alarm 9C, detail 01) occurs when the operation starts and home position return cannot be
executed. Reexamine the setting value of the Z-phase mask amount.
(a) The value calculated by Z-phase mask amount
electronic gear numerator (CMX) electronic gear
denominator (CDV) exceeds 32 bits.
(b) The value calculated by the Z-phase mask amount
the travel distance to the Z-phase exceeds 32 bits.
