Monitoring and driving the wire feed motor
The wire feed motor is driven and monitored by the pc-board DMR-RT3. If the current consumption of the motor is
too high, the machine stops with the error code E08 “Motor overcurrent”.
Motor identication
The pc-board DMR-RT3 is also used in other machines with other motors, not only at the MicorMIG. Because
of this, a identication (cable-bridge at connector X13, pins 5 and 11) is needed to indicate that the DMR-RT3 is
used in a MicorMIG machine. This cable must always be present at every MicorMIG machine.
