A guide to resolving the A783 alarm in ABB ACS880 and ACS580 drives. Learn why the drive blocks motor optimization and how to complete the ID run successfully. ABB Drive Guide: Alarm A783 Alarm A783 Meaning: Motor control optimization blocked The A783 alarm is a warning message typically found in ABB's all-compatible drive family (ACS880, ACS580, etc.). It indicates that the drive's internal motor control algorithm is attempting to optimize or identify motor parameters, but a specific condition is preventing it from completing the process. Important: A783 is an alarm, not a fault. The drive will likely still run, but motor performance (torque accuracy and efficiency) may not be optimal until the optimization is completed. Common Causes Pending ID Run: A motor Identification Run (ID Run) has been requested but not yet performed. Autophasing Required: For Permanent Magnet (PM) motors, the drive needs t...

A technical deep-dive into the 7310 Overcurrent fault on ABB ACS380 drives. Learn about mechanical jams, electrical shorts, and parameter tuning to resolve this trip.   ABB ACS380 Troubleshooting: Fault 7310 Fault 7310 Description: Overcurrent (Instantaneous Peak) The 7310 Overcurrent fault on an ACS380 indicates that the drive's output current has reached the hardware trip level. This is a protective measure to prevent the internal IGBTs (power transistors) from burning out due to excessive load or a short circuit. Primary Causes Sudden Load Increase: The machinery driven by the motor (pump, conveyor, mixer) has jammed or become overloaded. Short Deceleration/Acceleration: The ramp times are too aggressive for the inertia of the load. Electrical Short: A short circuit in the motor cables or the motor windings themselves. Incorrect Motor Data: The parameters in Group 99 do not match the motor nameplate. Drive Undersized: The...

A guide to understanding the Emergency Stop OFF2 condition on ABB ACS880 drives. Learn the difference between OFF1, OFF2, and OFF3, and how to troubleshoot Fault 71B1.   ABB ACS880: Emergency Stop OFF2 In the ABB ACS880 ecosystem, an "Emergency Stop OFF2" command is a safety or operational state that triggers an immediate Coast-to-Stop . When this command is received, the drive instantly stops firing the IGBTs (power transistors), disconnecting power from the motor and allowing it to spin down freely under its own inertia. Fault Code: 71B1 Display Message: Emergency stop (OFF2) Action: The drive trips and the motor coasts to a stop. The drive cannot be restarted until the signal is reset. OFF2 vs. Other Stop Modes Mode Type Action OFF1 Normal Stop S...

Understanding Alarm AFF6: Identification Run On the ABB ACS560 general-purpose drive, seeing the code AFF6 on the display is not a sign of a hardware failure. Instead, it is a notification that the drive is prepared and waiting to perform a motor tuning procedure.   Alarm AFF6 Meaning: Identification Run (ID Run) is selected and the drive is waiting for a Start command, OR the ID Run is currently in progress. Why is this Alarm appearing? Initial Commissioning: You (or another technician) have selected an ID Run mode in Parameter 99.13 . Parameter Reset: Sometimes, after a factory reset or changing critical motor data in Group 99, the drive requests an ID Run to ensure motor control accuracy. Wait State: The drive shows AFF6 to tell you: "I am ready to calibrate, please give me a Start signal." How to Resolve AFF6 Option A: Perform the ID Run (Recommended) For the best motor perfo...

A2025 alarm in ABB drive indicates FIRST START (Motor Identification Magnetization. This means the drive is performing its First Start evaluation .   Understanding the A2025 Alarm in ABB Drives If you are working with ABB drives like the ACS355, ACS550, or ACS510 , you might encounter the A2025 code on your control panel. While seeing an alarm code can be concerning, the A2025 is unique because it is often part of a standard operational process. Alarm Code: A2025 Meaning: FIRST START (Motor Identification Magnetization) What Causes the A2025 Alarm? The A2025 alarm is triggered when the drive is performing its First Start evaluation . This typically happens in the following scenarios: Initial Commissioning: The first time the motor is run after entering motor parameters (Group 99). Parameter Changes: After significant changes to motor data or switching control modes. ID Run: When the drive is performing a Motor Identificat...

If you are seeing the A2010 alarm on your ABB drive (common in ACS150, ACS310, ACS355, ACS510, and ACS550 series), it indicates a Motor Overtemperature condition. Unlike a "Fault" (which stops the drive immediately), an Alarm is a warning that the motor is running hotter than its calculated or measured limit.  If the temperature continues to rise, it will eventually trigger a Fault 0009 , which will trip the drive to protect the motor.     Common Causes Excessive Load: The motor is being asked to do more work than it is rated for, drawing high current and generating heat. Inadequate Cooling: The motor fan might be broken, the cooling fins might be clogged with dust, or the ambient temperature in the room is too high. Low Speed Operation: If a standard motor runs at very low speeds for a long time, its internal fan doesn’t spin fast enough to cool it down. Incorrect Parameter Settings: The drive "estimates" motor temperature using a thermal model.   If y...

Fault 7510 in ABB ACS800 drive indicates a COMM MODULE fault. This means loss of cyclic communication between the drive and the fieldbus master (PLC). Why is this happening? Before you start swapping out expensive parts, let’s look at the usual suspects: Cable Issues: A loose connector, a crimped fiber optic cable, or electromagnetic interference (EMI) disrupting the signal. Module Seat: The fieldbus adapter might not be seated properly in its slot on the RMIO board. Timeouts: The "Comm Loss Timeout" setting in the drive is too aggressive for the network traffic. PLC State: The Master PLC might be in 'Stop' mode or the network itself has crashed.  Troubleshooting Checklist Step Action What to look for 1 Check the LEDs Look at the Fieldbus module. If the "Link" light is off or "Host" is red, the module isn't talking to the drive. 2 Verify Parameter 30.18 Check the COMM FAULT FUNC . If it’s set to "FAULT," the drive trips. You can ...

A5001 code on an ABB ACS550 drive indicates "drive not responding". This means communication failure between the control panel and the main control board. Common Causes and Troubleshooting: Communication Loss: The control panel cannot communicate with the main processor, often due to a damaged CPU. Power Issue: Lack of 3.3V DC power at connector X3 on the WINT1011C power board. Loose Connections: Check that the control panel is properly seated on the drive. Power Cycle: Attempt to power cycle the drive to clear the fault. Hardware Failure: If the error persists, it usually requires replacing the control board or the entire drive unit.

A6A4 Motor Nominal Value fault on an ABB ACS880 drive means the drive has detected an inconsistency in the motor data you’ve entered. This fault is essentially a "logic check" failure. The drive’s internal firmware compares the values in Parameter Group 99 and determines that the physics of the motor you described don't make sense. A6A4: Causes and Remedies Table Probable Cause Detailed Explanation Corrective Remedy Incorrect Speed (RPM) Entering the "Synchronous" speed (e.g., 1500 or 1800) instead of the "Rated" speed (e.g., 1475 or 1760). Check the motor nameplate. Enter the exact Nominal Speed (including slip) into Par. 99.09 . Power/Current Mismatch The entered Power (kW/hp) is mathematically impossible given the Voltage and Current. Verify 99.06 (Current) and 99.10 (Power) . Ensure 96.16 is set to the correct unit (kW vs hp). Voltage/Wiring Conflict The motor is wired for Delta ( Δ ) but the drive is programmed for Star ( Y ) voltage (or vice...

F0001 fault in an ABB drive indicates an overcurrent trip , meaning the motor current has exceeded the drive's internal threshold, usually due to excessive load, short circuits in the motor/cables, or damaged internal hardware .   Causes for f0001 fault in abb drive: Excessive Load : The motor is overloaded or jammed mechanically. Short Circuit : Short circuit in the motor cable(s) or the motor itself. Acceleration Time : Acceleration time is too short. Internal Damage : Damaged IGBT modules or internal hardware Solution: Disconnect the motor cable from the VFD and attempt to run the drive. If the F0001 fault persists, the drive's internal hardware is damaged and likely requires professional repair. If the fault disappears with the motor disconnected, inspect the motor and cable for short circuits or insulation issues. Check for acceleration time (\(t_{acc}\)) settings—too short can cause overcurrent. Verify if the motor is stalled or experiencing a mechanical blockage
