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
