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.

Description
Macro drive unit
Controlling the motor using the
digital inputs of the inverter:
BI: 2/3 wire control command 1 (ON/OFF1 clockwise rotation)
BI: 2/3 wire control command 2 (ON/OFF1 counter-clockwise rotation)
Example: p3331[0] = 722.0 ⇒ if CDS 0 (index[0]) is selected, the inverter
receives its ON/OFF1 counter-clockwise command via DI 0.
Function
OFF1: The motor stops.
ON: Clockwise motor rotation.
ON: Counter-clockwise motor rotation.
ON: The motor direction of rotation is based on the signal that
assumes status "1" first.
