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.
General data, 400 V inverters
Line voltage
380 V … 480 V 3-ph. AC ± 10 %
3 AC 380 V … 480 V -20 %, +10 %
3 AC 0 V … 0.95 x input voltage (max.)
0 … 550 Hz, depending on the control mode
Line impedance FSA … FSC
Uk ≥ 1 %, for lower values, we recommend a line reactor, or a Power Module
with the next higher power rating.
Line reactor not required
Power factor λ FSA … FSC
0.7 without line reactor for Uk ≥ 1 %
0.85 with line reactor for Uk < 1 %
0.95 line reactor not required
< LO base load input current
Overvoltage category acc.
The inverter insulation is designed for surge voltages according to overvoltage Category III.
Pulse frequency 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.
Short-circuit current rating
(SCCR)
FSA … FSC ≤ 100 kA rms
FSD … FSF ≤ 65 kA rms
