i have the following problem on a crane:
the fast action fuses wich are installed on output of the dc drive (simoreg) burn sometimes during the driving of dc motor for rotating arm .
conection is mains > fuses > inverter > fast action fuses > motor
some hints about what could happen? . motor is about 200 kw
or less . note that the first fuses dont burn out only the fast acting ones on output of the drive.
