Torque Description: This is an additional function for torque control in the drive. The additive torque command value is
added to the torque command value (parameter 80) in the drive.

Name: +Torque_Limit_0 Data Display: Decimal R/W
Parameter No.
82
File:
Servo Loop
Group:
0 Description: The positive torque limit value limits the maximum torque in the positive direction. If the torque
limit value is exceeded, the drive sets the status 'T
≥ T
limit
' in C3D (parameter 13). There are 8 sets of + Torque
Limit and - Torque limit parameters. +Torque_Limit_0 applies to group zero.
