Chapter 5 – Troubleshooting & maintenance
2 - ERROR RESET
A stored error can be cancelled as follows:
• by means of the parameter setting software Visual Amplifier Setup, via the serial link RS232,
• by means of the RESET function issued from the CANopen bus,
• by switching off the amplifier supply.
3 - OPERATION PROBLEMS
3.1 - MOTOR DOES NOT MOVE
• Check that the amplifier is on.
• Check for no error on the amplifier.
• Check the wiring of the logic command inputs.
• Check that the amplifier is enabled.
3.2 - MOTOR ENABLED BUT LITTLE TORQUE
• Check the Max. current and Rated current parameters.
3.3 - SHAFT LOCKED – ERRATIC OSCILLATIONS - ROTATION AT MAXIMUM SPEED
• Check the resolver or encoder wiring on the amplifier connector as well as the mechanical fastening of the
position feedback sensor on the motor.
• Check for the correct motor selection in the MOTOR LIST module.
• Check the value of the Motor parameters in the Advanced Functions menu and renew the AUTO-PHASING
command, with unloaded motor, if required.
3.4 - DISCONTINUOUS MOTOR ROTATIONS WITH ZERO TORQUE POSITIONS
• Check the wiring of the three phases between motor and amplifier.
3.5 - LOUD CRACKLING NOISE IN THE MOTOR AT STANDSTILL
• Check that the Motor - Amplifier - Host system ground connections comply with the wiring recommendations.
• Check the rigidity of the mechanical transmission chain between motor and load (backlashes and elasticity in
the gears and couplings).
• Start a new Autotuning procedure by selecting a lower bandwidth than the initial one.
4 - SERVICE AND MAINTENANCE
When exchanging a amplifier on a machine, proceed as follows:
• Check that the new amplifier has got the same voltage and current ratings as well as the same hardware
configuration as the one to be replaced.
• Reload and save the parameters of the old amplifier via the serial link or the CANopen interface.
The new amplifier is now ready for operation.
