6.4. THE LCD SHOWS “BELT MOTOR HALTED”
WARNING: Old SW version shows “DAMAGE ON THE BELT MOTOR SYSTEM”
instead of this message.
The machine displays this message if:
• it has detected a failure to actuate movement of the belt motor at the start of the training session;
• the movement of the belt motor is interrupted during the training session.
The most common causes are principally:
• One of the motor thermal cutouts has been tripped;
• The inverter has shut down for protection from a mains voltage fluctuation (spike or glitch).
In both cases it is recommended to turn off the machine — for at least one hour in the first case, and
for a few minutes in the second case — before resuming normal operation.
If the machine still does not operate correctly, follow the procedures (which differ depending on the
inverter model used) set out in the following paragraphs.
LENZE INVERTER
In our experience, when machines with the Lenze inverter display this error message, it is necessary
to replace the inverter. In any case, before doing this ensure that the motor is in good condition by
checking that:
• The thermal cutouts are not open;
• The motor phases are not short-circuited.
