Selection Criteria

• • Heavy starting behavior of the drive or short ramp-up times, or driving multiple motors with one inverter => Select inverter 1-2 power classes higher
  • Lead length > 25m => Select inverter 1 power class higher, use choke
  • 1-phase frequency inverter with 3-phase 230V output => Check if the connected motor is suitable for 230V (Delta) operation, otherwise use 3-phase inverter.
  • Match the inverter's performance data with the motor data => The rated current of the motor must be below the maximum output current of the inverter.
