TROUBLESHOOTING GUIDE
8 - TROUBLESHOOTING GUIDE
Incident Possible cause Remedy
Abnormal
noise
Originating in motor or machine being
driven?
Uncouple the motor from the equipment being driven and
test the motor on its own
Noisy motor The cause is mechanical
if the noise
persists after switching off the power
supply with the drive set to “freewheel”
mode (open enable or STO terminal(s))
• vibrations
• Check that the key conforms to the type of balancing
(see section 2.5)
• damaged bearings • change the bearings
• mechanical friction: ventilation,
coupling
• check installation
The cause is electrical
if the noise
stops after switching off the power supply
• check the power supply at the motor terminals
• check the drive settings
• normal voltage and 3 phases balanced • check the connection of the AC terminal block and the
tightening of the terminals
• abnormal voltage • check the power supply line
• phase imbalance • check the winding resistance
Other possible causes:
• incorrect settings
• drive malfunction
• refer to the Commander ID300/302 user and technical
guide ref.5512
Motor heats
abnormally
• faulty ventilation • check the environment
• clean the fan cover and the cooling fins
• check that the fan is correctly mounted
• unsuitable switching frequency • comply with the minimum switching frequency indicated
on the motor nameplate
• faulty supply voltage • check the voltage
• overload • check the current consumption in relation to that
indicated on the motor nameplate
• partial short circuit • check the electrical continuity of the windings and/or the
installation
• phase imbalance • check the winding resistance
Other possible causes:
• incorrect settings
• drive malfunction
• refer to the Commander ID300/302 user and technical
guide ref.5512
Motor does
not start
at no load
• Mechanical seizing
When switched off:
• check that rotation of the shaft is not locked
• broken power supply line • check the fuses, electrical protection
• thermal protection • check
on load
• phase imbalance
When switched off:
• check the resistance and continuity of the windings
• check the electrical protection
• drive • check the settings and sizing (max. current that can be
delivered by the drive)
• thermal protection • check
