Two pole mains supply of a drive controller with 3 phase mains input

Question:
In what way does the output power drive controller of 3-phase-power supply change, if power supply is 2 poles (1 pole)?

Answer:
  •    The connectable motor power (motor current) is reduced to ca. 55 % of the drive controller's rated power
  •    You always have to use the assigned mains choke (1 phase mains choke is sufficient).
  •    The mains current is ca. 110 % of the original output rated current

The 2 phase power supply is not authorized in case of increased rated power (Imax = 120 % IN).
