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