ABB ACS355 Common Fault Codes – Summary

ABB’s ACS355 machinery drive is designed to pack all of your machine building needs into one drive. This cost effective, versatile drive offers the best connectivity in its class, simple installation and commissioning, and advanced vector control flexible enough to run both asynchronous and permanent magnet motors. Pre-defined application macros are purposely engineered to make the ACS355 ideal for materials handling, food and beverage applications, rubber, plastic and wood processing, and much more.
Because the ACS355 is such a valuable tool, it can be a headache when something goes wrong. With over 50 fault codes to parse and diagnose, it may be difficult to identify where your drive is encountering issues. To help you diagnose issues you’re having with the ACS355, we ran a five-part series covering the most common fault codes encountered on the drive.
Below you will find a list of each fault covered in the series, a brief description of each fault and a hyperlink to each part in the series. We encourage you to read each part in full, as they include important information on possible causes, troubleshooting techniques and suggested resolutions for each fault.
 

 
Part 1 – Short Circuit and Supply Phase

• Short Circuit – “0004 SHORT CIRC” will display on the drive’s keypad. This fault means the drive detects a short circuit somewhere along the motor cables or in the motor itself. The fault can also be caused by a defective output transistor or a defective current sensor.
• Supply Phase – “0022 SUPPLY PHASE” will display on the drive’s keypad. This fault triggers because the intermediate circuit DC voltage is oscillating due to a missing input power line phase or a blown fuse. The DC voltage ripple must exceed 14 percent of the drive’s nominal DC voltage for the fault to trip.

 
Part 2 – Motor Overtemp and Overcurrent

• Motor Overtemp – “0009 MOTOR OVERTEMP” will display on the drive’s keypad. This fault indicates that the motor temperature is too high due to excessive load, insufficient motor power, inadequate cooling or incorrect startup data.
• Overcurrent – “0001 OVERCURRENT” will display on the drive’s keypad. This fault is triggered when the output current has exceeded the drive’s trip level, typically 325 percent of the drive’s nominal current rating.

 
Part 3 – ID Run Fail and Earth Fault

• ID Run Fail – “0011 ID RUN FAIL” will display on the drive’s keypad. This fault occurs when the drive cannot successfully complete the Motor ID Run process.
• Earth Fault – “0016 EARTH FAULT” will display on the drive’s keypad. This fault trips when the drive detects a ground fault at the motor cable or in the motor.

 
Part 4 – Heatsink Overtemp and Undervoltage

• Heatsink Overtemp – “0003 DEV OVERTEMP” will display on the drive’s keypad. This fault means the drive’s IGBT heatsink temperature has exceeded the trip limit. The trip limit for the drive is 135°C.
• Undervoltage – “0006 DC UNDERVOLT” will display on the drive’s keypad. When this fault trips, it is indicating that the drive detects insufficient intermediate DC voltage, likely due to a missing input power line phase, a blown fuse, a rectifier bridge internal fault or insufficient input power

 
Part 5 – Overvoltage and Analog Input Loss

• Overvoltage – “0002 DC OVERVOLT” will display on the drive’s keypad. This fault means the drive detects excessive intermediate circuit DC voltage. The DC overvoltage trip limit is 210 percent of the drive’s max rated voltage.
• Analog Input Loss – “0007 AI1 LOSS” will display the drive’s keypad. This fault trips when the analog input AI1 signal has fallen below the limit defined by the drive. This limit is set at parameter 3021.
