Pulse frequency Factory setting: 4kHz Factory setting:
4kHz for converters with an LO base load power
<75kW
2kHz for converters with an LO base load power
≥75kW
Change in 2‑kHz steps:
2kHz…16kHz
Change in 2‑kHz steps:
2 kHz … 16 kHz for converters with an LO base load
power <55kW
2 kHz … 8 kHz for converters with an LO base load
power =55kW…90kW
2 kHz … 4 kHz for converters with an LO base load
power ≥110kW
If you increase the pulse frequency above the factory setting then the converter reduces the maximum
output current.
Permissible ambient
temperature
The permissible ambient temperature depends on the following conditions:
• Frame size (FS) of the converter
• Converter eldbus interface
• Operator panel
