Note: The maximum applicable motor output is given for a standard 4-pole motor. When selecting the actual motor and Drive, be sure that the Bypass
and Drive's rated output current is equal to, or greater than, the motor's rated current.
A 3-wire phase-shifting transformer is required on the power supply for 12-pulse rectification.
