When using a single-phase power supply, the VFD68 drive requires more single-phase power to createthree-phase power for the motor. Therefore, you must select a VFD68 drive with a higher maximum output current rating as follows:

  • R = Current (Ampere) rating of the controlled single-phase motor (or sum of ratings, if using multiple motors)
  • 2*R = minimum required output current for VFD68 drive

Select a VFD68 drive such that Maximum Output Current (Ampere) > 2*R (see Table 1).
