■ 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
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 given in the selection table (see section Sine filters) is used 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.
With other than recommended sine filters (see section Sine filters) and non-ABB Ex motors,
contact ABB.
