Two-wire control, method 2
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.
The inverter only accepts a new control command when the motor is at a standstill.
