Operation
4.4 Limiting Force
The SERVOPACK provides the following three methods for limiting output force to protect the machine.
4.4.1 Internal Force Limit
This function always limits maximum output force by setting values of following parameters.
The setting unit is a percentage of the motor rated force.
Note 1. Too small a force limit setting will result in insufficient force during acceleration and deceleration.
2. The maximum force of the linear servomotor is used whenever the value exceeds the maximum force is set.
