The operation frequency keeps increasing, even if the torque limit function is activated.
In this control mode, the actual speed is kept in sync with the operation frequency, while torque is held at a limit
level in spite of torque decrease when releasing the mechanical brake. The use of this function prevents the load
from failing and improves the motor’s response during inching operation.
