Three different modes can be selected for enabling the brake, see also Torque Charac-

m
Without holding torque preset
The torque for holding the load is built up after the brake is enabled. As a result of the
error value required for this, there is negligible sagging of the load.

If the outer load torque for a suspended axis is known, a compensating holding torque
can be applied before the brake is enabled:
m
With holding torque preset; brake enabled when drive torque = holding torque
The torque for holding the load is built up before the brake is enabled. When the torque
is reached, the "Enable Brake" command is sent. If the holding torque corresponds ex-
actly to the load torque, the drive does not sag. Any difference between the load torque
and the holding torque set in the parameters results in a negligible movement and is cor-
rected. If the holding torque set in the parameters cannot be achieved, the brake will not
be enabled and the drive will go into the "Error" state.
m
With holding torque preset: brake enabled when waiting time elapsed
The torque for holding the load is built up before the brake is enabled. Regardless of
whether the torque has been reached, the "Enable Brake" command is executed after a
preset time

. If the holding torque corresponds exactly to the load torque, the
drive does not sag. Any difference between the load torque and the holding torque set in
the parameters results in a negligible sag and is corrected.
