8.9 Limiting Torque
The SERVOPACK provides the following four methods for limiting output torque to protect the machine.
8.9.1 Internal Torque Limit (Limiting Maximum Output Torque)
Maximum torque is always limited to the values set in the following parameters.

Pn403 Reverse Torque Limit
Setting Range Setting Unit Factory Setting Setting Validation
0 to 800 % 800 Immediately
The settings in these parameters are constantly enabled. The setting unit is a percentage of rated torque.
If the torque limit is set higher than the maximum torque of the servomotor, the maximum torque of the servomotor is used
(as is the case with the 800% factory setting).

Internal Torque Limit
Too small a torque limit setting will result in insufficient torque during acceleration and deceleration.
