60º AVM - Pulse Width Modulation
Illustration 4.12: Derating of I
out
Size 3x, using 60º AVM in High torque mode (160% over torque)
Illustration 4.14: Derating of I
out
Size 3x, using 60º AVM in Normal torque mode (110% over tor-
que)
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.
