4.2 “High” voltage power supply
In “high ” voltage operating mode (b40.0=0), the converter can supplied as follows:
-
AC 3-phase network (200…480 ±10%)
Set b39.0=0 (default).
The converter can automatically detect the power supply voltage rating and adapts
internal operating parameters accordingly. When one of the power supply phases is
missing, b39.4=1.
-
AC 1-phase network (200…277 ±10%)
Set b39.0=1 and set the peak nominal value of 1-phase supply (v2*V
phase-neutral
) in
Pr206 . Save, switch off and on again the converter.
With both modes of AC power supply, when parameter b39.3=0 the input power supply is on. In case
of power loss the bit is set to one, anticipating the converter’s “under voltage” alarm that is based on
continuous voltage.
-
Continuous (288…678 ±10%)
Set b39.0=1 and set the nominal value of continuous voltage in Pr206. Save, switch
off and on again the converter.
In AC 1-phase or Continuous supply, it’s possible to limit the maximum output voltage of the drive
with the bit b39.1=1 and setting the threshold of the “over voltage” alarm in Pr207.
The automatic reset of “under voltage” undervoltage alarm can be forced by b99.8=1 with any kind
of power supply.
