56 Hardware Installation Manual, 01/2016, A5E36265179B-AA
3-phase 380 … 480 VAC ± 10%
3-phase 0 VAC … input voltage x 0.87 (max.)
0 … 550 Hz, depending on the control mode
< LO base load input current
Pulse frequency (factory
setting)
4 kHz
The pulse frequency can be adjusted up to 16 kHz in 2 kHz steps. The higher the pulse
frequency, the lower the available output current.
Current derating depending on the pulse frequency (Page 60)
