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 setting a positive value, the servo motor/linear servo motor will pull in the
direction of the servo motor rotation direction/linear servo motor travel direction at
positioning address increasing with the servo motor rotation amount/linear servo
motor travel distance unit. When setting a negative value, the servo motor/linear servo
motor will pull in the direction of the servo motor rotation direction/linear servo motor
travel direction at positioning address decreasing with the servo motor rotation
amount/linear servo motor travel distance unit.
For example, if a positive compensation amount is set when the [Pr. PA14 Rotation
direction selection/travel direction selection] setting is "1", the axis will be pulled to the
CW direction.
The vertical axis freefall prevention function is performed when all of the following
conditions are met.
1) The value of the parameter is other than "0".
2) The forced stop deceleration function is enabled.
3) Alarm occurs or EM2 turns off when the (linear) servo motor speed is zero speed or
less.
4) MBR (Electromagnetic brake interlock) was enabled in [Pr. PD23] to [Pr. PD26],
[Pr. PD28], and [Pr. PD47], and the base circuit shut-off delay time was set in
[Pr. PC16].

Function
selection C-D _ _ _ x Motor-less operation selection
Set the motor-less operation. This is not used in the linear servo motor control mode,
fully closed loop control, and DD motor control mode.
0: Disabled
1: Enabled
0h
_ _ x _ High-resolution analog input selection
Select the resolution of VC (Analog override).
When you change parameters, perform offset adjustment with [Pr. PC37 Analog
override offset]. The offset adjustment can be performed by executing VC automatic
offset. Setting "1" while using a servo amplifier other than MR-J4-_A_-RJ,
MR-J4-_A_-RU, and MR-J4-_A_-RZ will trigger [AL. 37].
0: Disabled
1: Enabled
This digit is available with servo amplifiers manufactured in November 2014 or later.
This digit is not available with MR-J4-03A6-RJ servo amplifiers.

0: [AL. 9B Error excessive warning] is disabled.
1: [AL. 9B Error excessive warning] is enabled.
This parameter is available with servo amplifiers with software version B4 or later.
