Two-wire control, method 3

You switch the motor on and off using a control command (ON/OFF1) and at the same time
select clockwise motor rotation. You also use the other control command to switch the motor
on and off, but in this case you select counter-clockwise rotation for the motor.
Unlike method 2, the inverter will accept the control commands at any time, regardless of the
motor speed.
