Operation
5.8 Limiting Force
The SERVOPACK provides the following four methods for limiting output force to protect the machine.
Note: The maximum force of the servomotor is used when the set value exceeds the maximum force.
5.8.1 Internal Force Limit
This function always limits maximum output force by setting values of following parameters.
The setting unit is a percentage of the rated force.
Note: If the settings of Pn483 and Pn484 are too low, the force may be insufficient for acceleration or deceleration of the
servomotor.
