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.

0013 CURRENT MEASUREMENT GAIN (0x3183)

+ Issue: The current measurement gain difference between U2 and W2 output phases is too large.
    Checks:
- Contact your local ABB representative.

0014 CABLE CROSS-CONNECTION (0x3181)

+ Issue: The input power and motor cable connection is incorrect (i.e., the input power cable is connected to the drive motor connection).
    Checks:
- Check the input power connections.

0015 SUPPLY PHASE (0x3130)

+ Issue: Intermediate circuit DC voltage fluctuates due to missing input power line phase or blown fuse.
    Checks:
- Check the input power line fuses.
- Check the input power supply imbalance.

0016 MOTOR PHASE (0x3182)

+ Issue: Motor circuit fault due to missing motor connection (not all three phases are connected).
    Checks:
- Connect the motor cable.

0017 ID-RUN FAILURE (0xFF84)

+ Issue: Motor ID Run not completed successfully.
    Checks:
- Check for a fault code extension in the fault recorder. See below for appropriate actions for each extension.
   Fault Code Extension: 1
- ID run cannot be completed because the maximum current setting and/or the drive's internal current limit is too low.
- Check the settings of parameters 99.06 MOT NOM CURRENT and 20.05 MAXIMUM CURRENT. Ensure that 20.05 MAXIMUM CURRENT > 99.06 MOT NOM CURRENT.
- Ensure that the drive is correctly sized for the motor.

   Fault Code Extension: 2
- ID run cannot be completed because the maximum speed setting and/or the calculated field weakening point is too low.
- Check the settings of parameters 99.07 MOT NOM VOLTAGE, 99.08 MOT NOM FREQ, 99.09 MOT NOM SPEED, 20.01 MAXIMUM SPEED, and 20.02 MINIMUM SPEED. Ensure that:
- 20.01 MAXIMUM SPEED > (0.55 × 99.09 MOT NOM SPEED) > (0.50 of synchronous speed),
- 20.02 MINIMUM SPEED < 0,
- Supply voltage > (0.66 × 99.07 MOT NOM VOLTAGE).

   Fault Code Extension: 3
- ID run cannot be completed because the maximum torque setting is too low.
- Check the settings of parameters 99.12 MOT NOM TORQUE and 20.06 MAXIMUM TORQUE. Ensure that 20.06 MAXIMUM TORQUE > 100%.

   Fault Code Extension: 4…16
- Internal fault. Contact your local ABB representative.

0018 CURR U2 MEASUREMENT (0x3184)

+ Issue: The measured offset error in U2 output phase current measurement is too large.
- Action: Contact your local ABB representative.

0019 CURR V2 MEASUREMENT (0x3185)

+ Issue: The measured offset error in V2 output phase current measurement is too large.
- Action: Contact your local ABB representative.

0020 CURR W2 MEASUREMENT (0x3186)

+ Issue: The measured offset error in W2 output phase current measurement is too large.
- Action: Contact your local ABB representative.

0021 STO1 LOSS (0x8182)

+ Issue: Safe Torque Off (STO) function is active, i.e., the safety circuit signal 1 connected between X6:1 and X6:3 is lost while the drive is stopped, and 46.07 STO DIAGNOSTIC setting is (2) Alarm or (3) No.
    Checks:
- Check the safety circuit connections. Refer to the appropriate drive hardware manual for more information.

0022 STO2 LOSS (0x8183)

+ Issue: Safe Torque Off (STO) function is active, i.e., the safety circuit signal 2 connected between X6:2 and X6:4 is lost while the drive is stopped, and 46.07 STO DIAGNOSTIC setting is (2) Alarm or (3) No.
    Checks:
- Check the safety circuit connections. Refer to the appropriate drive hardware manual for more information.

0024 INTERNAL CARD OVERTEMPERATURE (0x7182)

+ Issue: The temperature of the interface card between the power unit and control unit exceeds the internal fault limit.
    Checks:
- Wait for the drive 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.

0025 BC MODULE OVERTEMPERATURE (0x7183)

+ Issue: The temperature of the input bridge or brake chopper exceeds the internal fault limit.
    Checks:
- Wait for the drive 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.

0026 AUTOMATIC PHASING (0x3187)

+ Issue: The automatic phasing routine has failed.
    Checks:
- Try other automatic phasing modes if possible (see parameter 11.07 AUTOPHASING MODE).

0027 PU LOSS (0x5400)

+ Issue: The connection between the JCU Control Unit and the drive's power unit is lost.
    Checks:
- Check the connections between the JCU Control Unit and the power unit.

0028 PS COMMUNICATION (0x5480)

+ Issue: Communication errors have been detected between the JCU Control Unit and the drive's power unit.
    Checks:
- Check the connections between the JCU Control Unit and the power unit.
