Three-wire control, enable/clockwise/counterclockwise rotation
The "Enable" command is a precondition for switching on the motor. Commands "ON clockwise
rotation" and "ON counter-clockwise rotation" switch on the motor - and simultaneously select
a direction of rotation. Removing the enable switches the motor off (OFF1).
