Troubleshooting
Fault Possible cause Remedy
Rotor drive worn
or teeth broken
off
Excessive or frequent
stops/starts, very high
starting torque
Check whether the load of the application meets the specifications
of the Pallet Drive.
Check oil, maximum number of stops/starts and permissible
starting torque.
Use frequency inverter with start-and-stop ramps (0.5 s or more).
Toothed sprocket
worn or teeth/
bolts broken off
Start-up under overload
and/or impact load or
while blocked
Check whether the application and load meet the specifications of
the Pallet Drive.
Check whether start-up is blocked.
Use frequency inverter with start-and-stop ramps (0.5 s or more).
Complete or
temporary failure
of brake and
rectifier
Wrong operating voltage
applied
Ensure that the correct rectifier was installed and that the correct
input voltage (V/ph/Hz) is present.
Wrong connection Never connect the rectifier to the frequency inverter.
Ensure that the brake was connected according to connection
diagram.
Insufficient shielding
against external voltage
spikes from cables and
external devices
Ensure that all cables between brake, rectifier and voltage supply
are shielded and grounded according to IEC recommendations.
Complete or
temporary failure
of brake and
rectifier
Voltage drop due to
cable with excessive
length
Check whether a voltage drop occurs in long cables and ensure
that the cable cross section meets the IEC specifications.
Excessive stops/starts Ensure that the specifications for brake and rectifier meet the
requirements of the application.
Wrong rectifier connected Contact Interroll. We will give you the name of the correct
rectifier for the corresponding brake and application.
Short circuit of brake
winding
Check continuity of winding and rectifier.
Slow switching
of brake and
rectifier
Wrong brake/wrong
rectifier selected or
specified
Ensure that the specifications for brake and rectifier meet the
requirements of the application.
