- Explanation
This variable can be used to monitor output torque of the motor operated by the inverter. The data monitored with this variable
corresponds to the data monitored by the torque monitoring function (d012). This variable is read-only.
- Sample program :
Program to increase the inverter output frequency when motor output torque is low (to automatically
accelerate the motor)
