PC54 Set the compensation amount of the vertical axis freefall prevention function.
RSUP1 Set it per servo motor rotation amount or linear servo motor travel distance.
Vertical axis When setting a positive value, the servo motor or linear servo motor moves in the
freefall direction set with [Pr. PA14] for the forward rotation pulse input. When setting a
prevention negative value, the servo motor or linear servo motor moves in the direction set with
compensation [Pr. PA14] for the reverse rotation pulse input.
amount
For example, if a positive compensation amount is set when the [Pr. PA14 Rotation
direction selection/travel direction selection] setting is "1", compensation will be
performed to the CW 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
5) MBR (Electromagnetic brake interlock) is enabled with [Pr. PD23] to [Pr. PD28],
Setting range: -25000 to 25000
