The operation frequency keeps increasing, even if the torque limit function i s activated.
In this control mode, the actual speed is kept in sync with the operati on frequency, while torque is held at a limit
level when it decreases as a result of the release of the mechanical bra ke. The use of this function prevents the
load from failing and improves the motor’s response during inching ope ration.
