Simple torque control using stall prevention function
I am planning to implement a simple torque limiting application for a winding machine using the stall prevention operation level (analog variable signal) of the FR-A500. Is it functionally possible?
A motor with capacity of around 11 kW is used and the winding torque is adjusted in accordance with thickness of the copper wire being wound.
The winding speed is also adjusted using a separate potentiometer.

Answer
Basically, torque control cannot be performed.
Instead, control speed to adjust the winding torque.
It is possible to use the current limit function to prevent the overtorque (overcurrent), however, speed hunting may occur when the current limit function is triggered.
