Brake monitoring function
The brake monitoring function is activated when the function Brake acknowledge is used. The brake
monitoring function compares the brake feedback to the control signal. In other words, a fault will be
issued if the feedback is missing when drive is in Run state and the output frequency is above the
opening limit and the fault delay has expired. A fault is also triggered if the brake feedback indicates
that the brake is open while the drive is in stop state.
In some cases it is possible that an encoder fault appears when the drive is run against closed
brake. The encoder fault can be disabled with Control Options B8 when the drive is controlling the
brake to be closed.
