ACS 850 Fault codes 3
ABB ACS 850 Fault Detection
What's in This Section?
This section lists alarm (warning) and fault messages with possible causes and corrective actions.
The code of the alarm/fault is displayed on the control panel of the drive and in the DriveStudio PC tool. An alarm or fault message indicates an abnormal condition of the drive.
Most alarm and fault causes can be identified and corrected using the information in this section. If not possible, contact an ABB representative.
In this section, alarms and faults are listed according to four-digit codes. The hexadecimal code in parentheses following the alarm/fault message is for fieldbus communication.
Safety
WARNING! Only authorized electricians can perform maintenance on the drive. Before starting to work with the drive, read the Safety Instructions on the first pages of the relevant Hardware Manual.
How to Reset
When the fault is cleared, it can be reset by pressing the RESET button on the drive control panel or by turning the supply voltage off and on for a while. The motor can be restarted after the fault is cleared.
A fault can also be reset from an external source selected with the 10.10 Fault reset option.
Fault History
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.
08.01 Active fault and 08.02 Last fault store the codes of the latest faults.
Alarms can be monitored through 08.05 Alarm word1 … 08.08 Alarm word4.
Alarm information is lost when the power is turned off or the fault is reset.
0039 ENCODER 1 (0x7301)
Encoder 1 feedback fault. If the fault occurs before the first startup without using encoder feedback:
- Check the cable and the order of the connector signal wires between the encoder and the encoder interface module (FEN-xx).
- If the fault occurs after encoder feedback has already been used or while the drive is running:
- Ensure that the encoder connection cables or the encoder are not damaged.
- Ensure that the connection of the encoder interface module (FEN-xx) or the module itself is not damaged.
- Check the grounding when communication disruptions are detected between the encoder interface module and the encoder.
- For more information about encoders, refer to parameter groups 90 Enc module selection, 92 Resolver conf, and 93 Pulse enc conf.
0040 ENCODER 2 (0x7381)
Encoder 2 feedback fault. Refer to fault 0039.
0045 FIELDBUS COMMUNICATION (0x7510)
Programmable fault:
50.02 Communication loss function
The cyclic communication between the drive and the fieldbus adapter module or the PLC and the fieldbus adapter module is lost.
- Check the status of the fieldbus communication.
- Refer to the relevant User Manual of the fieldbus adapter module.
- Check the settings of the 50 Fieldbus parameter group.
- Check the cable connections.
- Check if the communication master can communicate.
0046 FB MAPPING FILE (0x6306)
Drive internal fault. Contact your local ABB representative.
0047 MOTOR OVERHEATING (0x4310)
Programmable fault:
31.01 Motor temperature1 protection
The estimated motor temperature (based on the motor thermal model) exceeded the fault limit defined by the 31.04 Motor temperature1 fault limit parameter.
- Check the motor ratings and load.
- Ensure proper motor cooling: Check the cooling fan, clean cooling surfaces, etc.
- Check the fault limit value.
- Check the motor thermal model settings (parameters 31.09…31.14).
- Ensure the measured motor temperature exceeded the fault limit defined by the 31.04 Motor temperature1 fault limit parameter.
- Ensure the actual number of sensors matches the value set by the 31.02 Motor temperature1 source parameter.
- Check the motor ratings and load.
- Ensure proper motor cooling: Check the cooling fan, clean cooling surfaces, etc.
- Check the fault limit value.
0049 AI CONTROL (0x8110)
Programmable fault:
13.32 AI supervision function
An analog input exceeded the limit defined by the 13.33 AI supervision cw parameter.
- Check the source and connections of the analog input.
- Check the minimum and maximum limit settings of the analog input.
In this case, the source and connections of the analog input should be carefully examined. Ensure that the analog input is properly configured and fluctuates between expected values. Also, ensure that the limit settings of the analog input are set according to the requirements of your application. If these settings are set in a very narrow range, it can easily exceed the limits even under normal operating conditions. Therefore, it is important to set the analog input limits to reflect your actual operating conditions.
If the problem persists, additional tests can be performed to verify the accuracy of the signal source and the proper operation of the analog input module. These tests can help you better understand the source of the problem and find an appropriate solution. Issues with analog input are often caused by incorrect configuration, damaged cable connections, or faulty hardware. Therefore, it is beneficial to carefully check each of these components and, if necessary, contact your local ABB representative.
0050 and 0051 Encoder Cable Faults:
Check the connection of the encoder cables between the FEN-xx interface and the encoder. After any changes in cable connections, reconfigure the interface by turning the drive power off and on or by activating the 90.10 Enc par refresh parameter.
