Input power connection
Voltage ( U

) 208/220/230/240 VAC 3-phase ± 10 % for 230 VAC units
380/400/415 VAC 3-phase ± 10 % for 400 VAC units
380/400/415/440/460/480/500 VAC 3-phase ± 10 % for 500 VAC units
The output voltage can be raised with setting of parameter 23.01 DC VOLT REF. Example:
With 400 V supply voltage and 700 VDC intermediate DC circuit voltage, it is possible to
run a 500 V motor at the motor nominal voltage.
Prospective short-circuit
current (IEC 60439-1,
UL 508C) Maximum allowed prospective short-circuit current in the supply is 65 kA in a second
providing that the mains cable of the drive is protected with appropriate fuses.
US and Canada: The drive is suitable for use on a circuit capable of delivering not more
than 65 kA rms symmetrical amperes at the drive nominal voltage when protected by T
class fuses.
Frequency 48 to 63 Hz, maximum rate of change 17 %/s
Imbalance Max. ± 3 % of nominal phase to phase input voltage
Voltage dips Max. 25 %
