b) Maximum speed: if the speed
signal requires operation
above the speed limit than the

SHORT CIRCUIT PROTECTON
–
In case short circuits, a
current detection circuit will
open the power switches
(cutting the current) and avoiding
further damage to power devices
or compressor winding.
In case of a major failure in the
hardware (short circuit of two or
more power switches, a fuse will
brake the current supplied to the
inverter).
