Chapter 5 – Troubleshooting & maintenance
• If the BUSY error is displayed after execution of the Autotuning, this procedure has failed because of an
external cause and the calculated parameters are wrong.
Check at first the status of the INHIBIT input and of the limit switches. Then check that the motor shaft is free
during the execution of the procedure.
• If the BUSY fault is continuously displayed after the execution of the COGGING TORQUE ACQUISITION
procedure, the procedure has failed because of an external cause and the cogging torque acquisition is not
valid.
Check that the INHIBIT input is disabled.
Check that the limit switch inputs are not activated.
Check that the encoder is providing one marker pulse per motor revolution.
Check that the motor is unloaded and the shaft movement is free during the procedure.
Check that the motor current value corresponding to the cogging torque effect is lower than 5 % of the
amplifier current rating.
• This error may also occur during a homing procedure which time-out is to low.
1.3.2 - "EEPROM" ERROR
• Check for the presence of the EEPROM and check its correct orientation.
• If the error remains, the EEPROM may not be correctly initialized (CHECKSUM) or is not compatible with the
amplifier software.
• To cancel this error, make a new parameter setting of the amplifier and save the new parameters.
1.3.3 - "°C MOTOR" ERROR
If the error occurs when commissioning the amplifier:
• Check the CTN/CTP parameter setting, the Triggering threshold and the Warning threshold.
• Check the wiring of the thermal sensor on the amplifier.
If the error occurs during the operation:
• Check that the triggering threshold is compliant with the manufacturer's specifications of the sensor.
• Check the motor temperature and look for the reason of this overheating (mechanical shaft overload, duty
cycle too high, ...).
1.3.4 - "POWER STAGE" ERROR
The POWER STAGE fault groups all faults issued from the power board:
o Power supply overvoltage.
o Phase/ground short-circuit.
o Phase/phase short-circuit.
o Fan.
o Power stage short-circuit.
o Power stage overtemperature (on CD1-k-400/I only).
o PWM control error.
o Power stage supply.
o Braking system error: transistor short-circuit or cycle too high.
The VISUAL DRIVE SETUP software allows to identify the “Power stage” fault.
If the fault occurs when starting the amplifier:
 Check the AC voltage on the L1 - L2 - L3 inputs of the X9 connector.
CD1-k-230/I amplifier : 196 VAC < VAC < 253 VAC
CD1-k-400/I amplifier : 340 VAC < VAC < 528 VAC
