10.4 Torque limit
The maximum output torque of the motor can be limited by turning the TL input ON. Use this input to
suppress motor torque, for your safety.
Follow the steps below to limit the maximum output torque of the motor during positioning operation:
Step 1 Setting the torque limit value
Step 2 Limiting the torque
Step 1 Setting the torque limit value
Set a torque limit value under each of eight operation data numbers from 0 to 7.
When the system parameter for analog input signals [SyS-1-05] is set to “Enable,” two analog points as well
as six digital points are available to assign settings. If the parameter is set to “Disable,” eight digital points are
available to assign settings.
Set the torque limit value as an integer percentage of the rated torque being 100%, in a range of 0 to 300%.
