ProNet Plus Series AC Servo User's Manual
- 107 -
·The setting unit is a percentage of rated torque.
·The maximum torque of the servomotor is used, even though the torque limit is set higher than the maximum torque of
the servomotor. (as is the case with the 300% factory setting)

■Note:
Too small a torque limit setting will result in insufficient torque during acceleration and deceleration.
4.9.2 External Torque Limit
This function allows the torque to be limited at specific times during machine operation, for example, during press stops
and hold operations for robot workpieces.
An input signal is used to enable the torque limits previously set in parameters.
