ABB DCS800 DC Drive Fault Codes List
Troubleshooting guide for ABB DCS800 DC drives. Find a complete list of DCS800 fault codes, armature and field errors, and learn how to reset your DC drive safely. The ABB DCS800 is one of the most reliable industrial DC drives on the market, commonly used in high-torque applications like extruders, winches, and heavy machinery. Since DC motor control involves managing both the armature and field circuits, the drive uses a sophisticated diagnostic system to monitor thyristor performance and motor feedback. When an issue occurs, the drive stops and displays a fault code on its control panel. Understanding these ABB DCS800 fault codes is vital for technicians to identify whether the problem lies within the drive, the thyristor bridge, or the DC motor itself. Alarms vs. Faults on the DCS800 The DCS800 uses the following status indicators to alert you to problems: Alarms (Axxx): These are warnings. The drive continues to run, but the control panel blinks a message. This us...
