After a time delay (normally 0.3s), the delayed contact of the brake contactor opens, which disconnects the<br />
supply from terminal 3 and the rectifier changes to a half wave type. Half wave operation prevents heating of<br />
the brake coil and is enough to keep the brake open.<br />
To close the brake, the brake contactor disconnects the supply to terminals 1 and 2. The released brake<br />
contactor also opens the brake coil DC-circuit, which speeds closing of the brake. The purpose of the varistor<br />
there is overvoltage protection for K7 contacts and the brake coil.<br />
