Mains connection and maneuver diagram
The delayed disconnection of KA3 contacts is useful so:
 The Drive_Enable stays active while the motor brakes at maximum torque.
 The brake holds the motor after it has stopped.
NOTE. When installing a transformer, the secondary must have a star connection
and its middle point must be connected to ground.
NOTE. The use of fuses is a must.
