Set the Torque Limit Value Using an Analog Input
You can change the analog input level torque limit value by setting the torque limit in multi-function analog
input terminals A2 and A3.
The analog input terminal signal level is factory-set as follows:
Multi-function analog input terminal A2: 4 to 20 mA
Multi-function analog input terminal A3: 0 to 10
The following diagram shows the relationship between the torque limits.
