ABB ACS 310 Alarm and Fault Indicators

A fault is indicated by a red LED. See the LEDs section on page 315.
An alarm or fault message on the panel display indicates an abnormal condition of the drive.
Most alarm and fault causes can be identified and corrected using the information provided in this section. If not corrected, contact an ABB representative.
The four-digit code number in parentheses after a fault is used for field communication. See the Field Communication Control with Embedded Field Communication section on page 271.

How to Reset

The drive can be reset by pressing a key on the keypad (Basic Control Panel) or (Assistant Control Panel), via a digital input or field communication, or by turning off the supply voltage for a while. The source of the fault reset signal is selected with the 1604 FAULT RESET SEL parameter. After the fault is cleared, the motor can be restarted.

Fault History

When a fault is detected, it is recorded in the fault history. The latest faults are stored with a timestamp.
Parameters 0401 LAST FAULT, 0412 PREVIOUS FAULT 1, and 0413 PREVIOUS FAULT 2 store the latest faults. Parameters 0404…0409 show the operating data of the drive when the latest fault occurred. The Assistant Control Panel provides additional information about the fault history. See the Fault Logger Mode section on page 94 for more information.

0001 OVERCURRENT
Output current has exceeded the trigger level. Check the motor load.
Check the acceleration time (2202 and 2205).
Check the motor and motor cable (including phasing).
Check the environmental conditions. If the ambient temperature of the installation site exceeds 40 °C, the load capacity decreases.
See the Rating section on page 319.

0002 DC OVERVOLTAGE 
Excessive intermediate circuit DC voltage. The DC overvoltage trigger limit is 420 V for 200 V drives and 840 V for 400 V drives.
Check that the overvoltage controller is on (parameter 2005 OVERVOLTAGE CONT).
Check the input power line for static or transient overvoltage.
Check the deceleration time (2203, 2206).

0003 DEVICE OVERTEMPERATURE
Drive IGBT temperature is excessive. The fault trigger limit is 135 °C.
Check the environmental conditions. Also, see the Rating section on page 319.
Check the airflow and fan operation.
Compare the motor power with the drive power.

0004 SHORT CIRCUIT 
Short circuit in the motor cable(s) or motor.
Check the motor and motor cable.

0006 DC UNDERVOLTAGE
Intermediate circuit DC voltage is insufficient due to a missing input power line phase, fuse failure, rectifier bridge internal fault, or very low input power.
Check that the undervoltage controller is on (parameter 2006 UNDERVOLTAGE CONT).
Check the input power source and fuses.

0007 AI1 LOSS
(programmable fault function 3001, 3021)
The analog input AI1 signal has fallen below the limit defined by parameter 3021 AI1 FAULT LIMIT.
Check the fault function parameter settings.
Check the appropriate analog control signal levels.
Check the connections.

0008 AI2 LOSS
(programmable fault function 3001, 3022)
The analog input AI2 signal has fallen below the limit defined by parameter 3022 AI2 FAULT LIMIT.
Check the fault function parameter settings.
Check the appropriate analog control signal levels.
Check the connections.

0009 MOTOR OVERTEMPERATURE
(programmable fault function 3005…3009 / 3504)
The motor temperature is too high (or appears too high) due to overload, insufficient motor power, insufficient cooling, or incorrect start-up data.
Check the motor values, load, and cooling.
Check the start-up data.
Check the fault function parameters.
The measured motor temperature has exceeded the fault limit defined by parameter 3504 FAULT LIMIT.
Check the fault limit value.
Ensure that the actual number of sensors matches the value defined by the parameter (3501 SENSOR TYPE).
Allow the motor to cool down. Ensure proper motor cooling: Check the cooling fan, clean the cooling surfaces, etc.

0010 PANEL LOSS 
(programmable fault function 3002)
The control panel selected as the active control location for the drive has lost communication.
Check the panel connection.
Check the fault function parameters.
Check the control panel connector.

    Reattach the control panel in the mounting platform.
    If the drive is in external control mode (REM) and start/stop, direction commands, or references are set to be accepted through the control panel:

0012 MOTOR STALL
(programmable fault function 3010…3012)

    The motor is operating in the stall region due to overload or insufficient motor power.
    Check the motor load and drive ratings.
    Check the fault function parameters.
