In the case of main drives, the internal drive enable is
switched off immediately. The drive coasts to stop. After
the velocity has fallen below the minimum value, the
holding brake is applied.
In the case of error situation 2, the drive becomes torque- or force-free
after the error event. The braking effect, in addition to the axis friction, can
only be achieved by means of the holding brake. To limit the damage the
holding brake is controlled depending on the application (servo or main
drive).
