Three-wire control, method 1
With one control command, you enable the two other control commands. You switch the
motor off by withdrawing the enable (OFF1).
You switch the motor's direction of rotation to clockwise rotation with the positive edge of the
second control command. If the motor is still switched off, switch it on (ON).
You switch the motor's direction of rotation to counter-clockwise rotation with the positive
edge of the third control command. If the motor is still switched off, switch it on (ON).

Description
Macro drive unit
Controlling the motor using
the digital inputs of the in-
verter:
BI: 2/3 wire control command 1 (enable/OFF1)
BI: 2/3 wire control command 2 (ON clockwise rotation)
BI: 2/3 wire control command 3 (ON counter-clockwise rotation)
Example: p3332[0] = 722.0 ⇒ if CDS 0 (index[0]) is selected, the inverter
receives its ON counter-clockwise command via DI 0.
