[Torque Reduction]
Selection for torque reduction. When the torque reduction function is active
(1 “Active”), the current limit changes accordingly by the percentage defined
in Par 13 [Torq Red CurLim]. When this parameter is set to 0 “Not Active”,
torque reduction is not active.
For example:
Par 7 [Current Limit] (or Pars 8 [Current Lim Pos] and 9 [Current Lim Neg])
= 80%
Par 13 [Torq Red CurLim] = 70%
If Par 342 [Torque Reduction] = 0 “Not Active”, the current limit = 80%
If Par 342 [Torque Reduction] = 1 “Active”, the current limit = 70%
Note: This parameter can be assigned to a digital input.

[Zero Torque]
Sets the reference value for the armature current (Par 41 [Current Reg In]) to
zero so that the drive has no torque.
• “Not Active” = Par 41 [Current Reg In] is not set to zero.
• “Active” = Par 41 [Current Reg In] is set zero. The drive has no torque.

[TrqTpr Lim0]
The current limit of the current/speed curve that operates constantly up to
the speed set in Par 756 [TrqTpr Spd]. When the current/speed curve function
is enabled (set in Par 750 [TrqTpr Enable]), this parameter will override the
current limits set in Pars 10 [Cur Lim Pos Out] and 11 [Cur Lim Neg Out].
