Pr.54

OPR torque limit value

Set the value to limit the servomotor torque after reaching the creep speed during machine OPR.

Refer to Section 12.4.2 "Torque limit function" for details on the torque limits.

Pr.55

Deviation counter clear signal output time

Set the duration of the deviation counter clear signal output during a machine OPR operation using any of the following methods: the near-point dog method, stopper methods 1) to 3), and count method 1). (For details, refer to your drive unit manual.)

Pr.56

Speed designation during OP shift

Set the operation speed for when a value other than "0" is set for " Pr.53 OP shift

amount". Select the setting from " Pr.46 OPR speed" or "

0 : Designate " Pr.46 OPR speed" as the setting value.
