The output current from the
converter has reached such

Check the connection cables particularly on the motor
side of the terminal block to remove any dispersion or
short-circuiting; check the insulation of the motor
itself, doing a dielectric rigidity test, and if necessary
replace.
Check that the converter’s power circuit is integral by
setting it running after switching on the connections; if
the safety device intervenes replace the power circuit.
If the safety device only intervenes during working it
could be a matter of regulation (replace it along with
the current transducers) or vibrations causing DC
