Three-wire control, enable/clockwise/counterclockwise rotation

Function description
Figure 8-9
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).
