_ _ _ x Encoder pulse count polarity selection
0: Encoder pulse increasing direction in the servo motor CCW or
positive direction
1: Encoder pulse decreasing direction in the servo motor CCW or
positive direction
0h
_ _ x _ For manufacturer setting 0h
_ x _ _ Selection of A/B/Z-phase input interface encoder Z-phase
connection judgment function
This is used to select a non-signal detection of A/B/Z-phase input
interface encoder pulse train signal used as linear encoder or load-
side encoder.
This digit is enabled only when you use an A/B/Z-phase input
interface encoder. 0h

PC31 RSUP1 Vertical axis freefall prevention compensation amount
Set the compensation amount of the vertical axis freefall prevention function.
Set it per servo motor rotation amount or linear servo motor travel distance.
When a positive value is set, compensation is performed to the address increasing direction.
When a negative value is set, compensation is performed to the address decreasing direction.
The vertical axis freefall prevention function is performed when all of the following conditions
are met.
1) Position control mode
2) The value of the parameter is other than "0".
3) The forced stop deceleration function is enabled.
4) Alarm occurs or EM2 turns off when the (linear) servo motor speed is zero speed or less.
5) MBR (Electromagnetic brake interlock) was enabled in [Pr. PD07] to [Pr. PD09], and the
base circuit shut-off delay time was set in [Pr. PC02].
