Parameter No.
81
File:
Control
Group:
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.
