Technical data, 400 V inverters

Motors for 400 V Power Modules
For the 400 V Power Modules, induction motors are permissible in the range from
25 % ... 150 % of the inverter power without any restrictions.
Use motors for inverter operation or with higher insulation levels.

< LO base load input current
The inverter insulation is designed for surge voltages according to overvoltage Category III.
Factory setting
4 kHz for devices with an LO base load power < 75 kW
•
2 kHz for devices with an LO base load power ≥ 75 kW
•
Can be adjusted in 2 kHz steps as follows:
2 kHz ... 16 kHz for devices with an LO base load power < 55 kW
•
2 kHz ... 8 kHz for devices with an LO base load power ≥ 55 kW
•
If you increase the pulse frequency, the inverter reduces the maximum output current.
FSA ... FSC ≤ 100 kA rms
FSD ... FSF ≤ 65 kA rms
