Is your machine stopped because of an ABB Drive Fault?

Nothing is worse than a production halt due to a VFD error. If your ABB ACS880, ACS550, or ACS355 drive is flashing Fault Code F0001 or F0002, don’t panic. These are the most common issues we fix at JRM Solutions.

Here is a quick guide to understanding what these faults mean and when you need professional repair.

1. What is Fault F0001 (Overcurrent)?

The F0001 error indicates that the drive has detected an output current higher than the limit. In simple terms, the VFD is “pushing” too much power, or there is a short circuit.

Common Causes:

• Short circuit in the motor cable.

• The motor is jammed or carrying a heavy load.

• Damaged IGBT (Internal power component) inside the VFD.

Quick Troubleshooting (DIY):

1. Disconnect the motor cable from the VFD and try to run the drive. If the fault still appears, the internal VFD hardware is damaged. You need a repair service immediately.

2. If the fault goes away, check your motor and cables for moisture or cuts.

2. What is Fault F0002 (DC Overvoltage)?

This usually happens when the motor decelerates (stops) too fast. The energy flows back into the drive, causing high voltage on the DC bus.

Solution:

• Increase the “Deceleration Time” in the parameters.

• Check if the braking resistor is working correctly.

When to Call JRM Solutions?

If you have checked the motor and cables but the Red Light (Fault) is still blinking, the problem is inside the VFD (Logic Board or IGBT Card).

Do not try to open the drive yourself, as high voltage capacitors can be dangerous.

At JRM Solutions (Noida), we offer:

• Component Level Repair: We replace specific burnt parts (IGBTs, Capacitors) instead of changing the whole board, saving you 60% cost.

• Test Bench Facility: We test every drive on load before delivery.

• Quick Turnaround: We understand production loss; we aim for same-day or next-day repair.
