Table 6.13 Derating at 480 V
6.7.2 Automatic Derating
The frequency converter constantly checks for critical
levels:
•
Critical high temperature on the control card or
heatsink
•
High motor load
•
Low motor speed
As a response to a critical level, the frequency converter
adjusts the switching frequency. For low motor speed, the
frequency converter can also force the PWM pattern to
SFAVM.
