Torque Limits: L7
User constants for torque limits are shown in the following table.
Note The forward torque limit is the limit value when the analog input signal generates forward torque. This torque limit setting is enabled even when the
analog input signal generates forward torque while the motor is operating (regeneration).
* The factory setting will change when the control method is changed.

detection selection 2 Multi-function output for over-
torque detection 1 is output to
multi-function contact output
when overtorque detection 1
NO or overtorque detection 1
NC is selected. Multi-function
output for overtorque detection
2 is output to multi-function
contact output when overtorque
detection 2 NO or overtorque
detection 2 NC is selected.
