Pulse frequency Factory setting: 4 kHz
Change in 2‑kHz steps:
2 kHz ... 16 kHz
If you increase the pulse frequency above the factory setting then the inverter reduces the maximum
output current.
Permissible ambi‐ The permissible ambient temperature depends on the following conditions:
ent temperature
● Frame size (FS) of the inverter
● Inverter fieldbus interface
● Operator panel
