60º AVM - Pulse Width Modulation
Illustration 4.12: Derating of I
frame size C, using 60º AVM in High torque mode (160%
over torque)
Illustration 4.14: Derating of I
frame size C, using 60º AVM in Normal torque mode (110%
over torque)
Frame size C2, 525-690 V
Illustration 4.16: Output current derating with switching fre-
quency and ambient temperature for frame size C2, 60º
AVM. Note: The graph is drawn with the current as absolute
value and is valid for both high and normal overload.
