￭ Switching frequency derating
Switching frequencies other than default can require output current derating. Contact ABB
for more information.
￭ Deratings for special settings in the drive control program
Enabling special settings in the drive control program can require output current derating.
Ex motor, sine filter, low noise
The table below gives the deratings for these cases:
• drive is used with an ABB motor for explosive atmospheres (Ex) and EX motor in
Parameter 95.15 Special HW settings is enabled
•
sine filter option +E206 is selected and ABB sine filter in Parameter 95.15 Special HW
settings is enabled
•
Low noise optimization is selected in Parameter 97.09 Switching freq mode.
