Set the compensation amount of the vertical axis freefall prevention function.
Set the amount in a unit of the servo motor rotation.
The servo motor pulls up in a rotation direction of increasing address for the positive
value and in a direction of decreasing address for the negative value in a unit of the
servo motor rotation.
For example, when [Pr. PA14 Rotation direction selection/travel direction selection]
is set to "1" and a positive value is set for the compensation amount, the servo motor
pulls up in the CW direction.
The vertical axis freefall prevention function is performed when all of the following
conditions are met.
1) The setting value of this parameter is other than "0".
2) The forced stop deceleration function is enabled.
3) Alarm has occurred or EM2 has turned off when the servo motor rotates at the
zero speed or less.
4) MBR (Electromagnetic brake interlock) was enabled in [Pr. PD24], [Pr. PD25],
and [Pr. PD28], and the base circuit shut-off delay time was set in [Pr. PC16].
Setting range: -25000 to 25000
Set the motor-less operation.
0: Disabled
1: Enabled
0: [AL. 9B Error excessive warning] is disabled.
1: [AL. 9B Error excessive warning] is enabled.
Set the upper limit of the mark detection.
Upper and lower are a set.

The unit will be changed to 10
the setting of [Pr. PT01].
Set a same sign for [Pr. PC66] and [Pr. PC67]. A different sign will be recognized as
minus sign data.
When changing the direction to address decreasing, change it from the - side of the
mark detection ([Pr. PC68] and [Pr. PC69]). An incorrect order of the setting will
trigger [AL. 37]. Therefore, cycling power may be required after [Pr. PC66] to [Pr.
PC69] are all set.
