I remember that the RP06 or its brothers uses 3 phase

warnings that the phases have to be hooked up right or the pack
will
unscrew at powerup (due to spinning in the wrong direction).
There might be other drives that do that, but not the RP06 (or RP05). The
US model is wired for 120/208V three phase Y power. They run a single phase
motor between two phases (208V), and the power supply for the logic between
a phase and neutral (120V). Nothing in it depends on the phase ordering.
They have an outlet for chaining power to a second drive (but not more than
one), and they do rotate the phases between the inlet and outlet.
The motor is rated to run on up to 240V nominal, so it can easily be wired
to run on 120/240V split phase if three phase is not available.
