ABB ACS100 Fault Codes and Alarm HelpFrom the ABB service manual I compiled a list of the ACS100 Fault codes or ACS100 Alarm codes, ACS100 Error codes, or whatever you like to call them. There's a lot of good information here regarding problem solving and clearing alarms on the ACS100. This list or errors will help you solve problems fast.
Alarm and Fault displays: The seven-segment display unit of control panel indicates alarms and faults using codes "ALxx" or "FLxx", where xx is the corresponding alarm or fault code. Alarms 1-6 arise from button operation.
Green LED blinks for AL10-16, meaning that the ACS 100 cannot fully follow the control commands. The faults are indicated by red LED.
The alarm and fault messages disappear by pressing MENU, ENTER or the arrow buttons of the control panel. The message will reappear after a few seconds if the keypad is not touched and the alarm or fault is still active. Last fault code is stored into parameter 102. This fault memory can be cleared from the control panel by pressing UP and DOWN buttons simultaneously in parameter set mode.
Resetting Faults (or alarms):Faults that are indicated by a red blinking LED are reset by turning the power off for a while. Other faults (indicated by red static LED) can be reset either from the control panel, by digital input, or switching the supply voltage off for a while. When the fault has been removed, the motor can be started. The ACS100 can be configured to automatically reset certain faults. (This would be done with parameter 505 AUTO RESET which I don't cover here)
OK with that being said, here are the ACS100 faults/alarms to hopefully give you ACS100 troubleshooting help:

ACS100 FAULT CODE LISTPlease Note that Faults (*) with red blinking LED are reset by turning the power off and on. The other faults are reset by pressing the START/STOP button. And here's the fault codes:
- FL 1 Overcurrent: Possible mechanical problem or Acc and/or Dec times may be too small.
- FL 2 DC overvoltage: Input voltage too high or Dec time may be too small.
- FL 3 ACS 100 overtemperature: Ambient temperature too high or Severe overload.
- FL 4 * Fault current: output earth fault or short circuit.
- FL 5 Output overload.
- FL 6 DC undervoltage.
- FL 7 Analogue input fault. (See parameter 501.)
- FL 8 Motor overtemperature. (See parameter 502.)
- FL 9 Panel disconnected from drive in local control. Note! If FL 9 is active when the power is turned off, the ACS100 will start in remote control (REM) when the power is turned back on.
- FL10 Parameters inconsistent. Check that AI min (fmin) is not greater than AI max (fmax).
- FL11 * DC bus ripple too large. Check supply.
- FL12 Reserved. Contact ABB motor/drive supplier.
- FL13 * Hardware error. Contact ABB motor/drive supplier.
- FL14 * Hardware error. Contact ABB motor/drive supplier.
- FL15 * Analogue input out of range. Check AI level.
- FL16 * Hardware error. Contact ABB motor/drive supplier.
- FL17 * Hardware error. Contact ABB motor/drive supplier.
- FL18 * Hardware error. Contact ABB motor/drive supplier.
- FL19 * Hardware error. Contact ABB motor/drive supplier.
- Full display blinking - Serial link failure or Bad connection between the control panel and the ACS100.
