ACSM1 Fault codes

Alarm and Fault Indications

+ Alarm/Fault Codes: The drive displays a four-digit code on its 7-segment display, indicating a specific alarm or fault. This code is crucial for identifying the cause of the problem.

+ Field Communication: The code number given in parentheses after the message is used for field communication.

How to Reset

+ Reset Methods: The drive can be reset by pressing the reset button on the PC tool or the RESET button on the control panel, or by temporarily turning off the supply voltage. The motor can be restarted after the fault is cleared.

+ External Reset: A fault can also be reset from an external source using the 10.08 FAULT RESET SEL parameter.

Fault History

+ Fault Recording: When a fault is detected, it is stored in the fault recorder with a timestamp. The fault history stores information on the last 16 faults of the drive. The last three faults are preserved at the top when the power is turned off.

+ Signals: The 8.01 ACTIVE FAULT and 8.02 LAST FAULT signals store the codes of the latest faults.

+ Alarm Monitoring: Alarm information can be monitored through the 8.05 ALARM WORD 1 to 8.08 ALARM WORD 4 alarm words. Alarm information is lost when the power is turned off or the fault is reset.

These details are important for understanding and troubleshooting alarms and faults encountered during the management and maintenance of the ABB ACSM1 drive.

0001 OVERCURRENT (0x2310)

+ Issue: Output current exceeds the internal fault limit.

  • Check motor load.
  • Check acceleration time. Refer to parameter group 25 SPEED REF RAMP on page 114.
  • Check the motor and motor cable (including phasing and star/delta connection).
  • Ensure the starting data in parameter group 99 matches the motor's rating plate.
  • Check that there are no power factor correction capacitors or surge suppressors in the motor cable.
  • Check the encoder cable (including phasing).

0002 DC OVERVOLTAGE (0x3210)

+ Issue: Intermediate circuit DC voltage is excessively high.

  • Check if the overvoltage controller is active, parameter 47.01 OVERVOLTAGE CTRL.
  • Check for static or transient overvoltage in the main supply.
  • Check the brake chopper and resistor (if used).
  • Check the deceleration time.
  • Use the stop-start function (if applicable).
  • Add a brake chopper and brake resistor to the frequency converter.

0003 DEVICE OVERTEMPERATURE (0x4210)

+ Issue: Measured drive temperature exceeds the internal fault limit.

  • Check environmental conditions.
  • Check air flow and fan operation.
  • Check for dust accumulation on cooling fins.
  • Compare motor power with unit power.

0004 SHORT CIRCUIT (0x2340)

+ Issue: There is a short circuit in the motor cable or motor.

  • Check the motor and motor cable.
  • Check that there are no power factor correction capacitors or surge suppressors in the motor cable.

0005 DC UNDERVOLTAGE (0x3220)

+ Issue: Intermediate circuit DC voltage is insufficient due to missing main phase, blown fuse, or internal fault in the rectifier bridge.

  • Check the main supply and fuses.

0006 GROUND FAULT (0x2330)

+ Issue: The drive detects an imbalance due to a ground fault, usually in the motor or motor cable.

  • Check that there are no power factor correction capacitors or surge suppressors in the motor cable.
  • Check for ground faults in the motor or motor cables:
    • Measure the insulation resistances of the motor and motor cable.
  • If a ground fault cannot be detected, contact your local ABB representative.

0007 FAN FAILURE (0xFF83)

+ Issue: The fan is not spinning freely or the fan connection is disconnected. Fan operation is monitored by measuring fan current.

  • Check the fan operation and connection. Ensure the fan is working properly and there are no connection issues. Check that the fan can spin freely without encountering any mechanical obstacles.

0008 IGBT OVERTEMPERATURE (0x7184)

+ Issue: Drive temperature exceeds the internal fault limit based on the thermal model.

  • Check environmental conditions.
  • Check air flow and fan operation.
  • Check for dust accumulation on cooling fins.
  • Compare motor power with unit power.

0009 BC WIRING (0x7111)

+ Issue: Short circuit in the brake resistor or brake chopper control failure.

  • Check the brake chopper and brake resistor connection.
  • Ensure the brake resistor is not damaged.

0010 BC SHORT CIRCUIT (0x7113)

+ Issue: Short circuit in the brake chopper IGBT.

  • Ensure the brake resistor is connected and not damaged.

0011 BC OVERHEATING (0x7181)

+ Issue: Brake chopper IGBT temperature exceeds the internal fault limit.

  • Wait for the chopper to cool down.
  • Check for excessive environmental temperature.
  • Check for cooling fan failure.
  • Check for obstructions in air flow.
  • Check the sizing and cooling of the cabinet.
  • Check the brake resistor overheat protection function settings, parameters 48.03…48.05.
  • Check that the braking cycle is within allowed limits.
  • Check that the drive supply AC voltage is not excessive.

0012 BR OVERHEATING (0x7112)

+ Issue: Brake resistor temperature exceeds the fault limit defined by parameter 48.06 BR TEMP FAULTLIM.

  • Stop the drive. Wait for the resistor to cool down.
  • Check the brake resistor overheat protection function settings, parameters 48.01…48.05.
