ACS 550 Fault codes 3
Hi everyone,
ABB ACS 500 drives detect fault conditions and report them through various means: green and red LEDs on the drive, the status LED on the control panel, the control panel display if available, as well as through Fault Word and Alarm Word parameter bits (from 0305 to 0309). Different displays are used depending on the severity of the fault, and the drive can be directed to ignore faults, report them as alarms, or report them as faults.
Red LED – Faults: When a serious fault is detected, the drive activates the red LED, a steady red status LED is shown on the control panel, an appropriate Fault Word parameter is set, the control panel display is updated with the fault code, and the motor is stopped. The fault code can be cleared from the control panel by pressing specific buttons.
Flashing Green LED – Alarms: For less severe faults, the indicator is only advisory, and the drive reports that it has detected an unusual condition. For these situations, the green LED on the drive and on the control panel if present flashes, an appropriate Alarm Word parameter is set, and the control panel display is updated with the alarm code and/or name. Alarm messages disappear after a few seconds but periodically return as long as the alarm condition persists.
Fault Reset: The ACS550 can be configured to automatically reset certain faults. Faults with a flashing red LED can be reset by turning off the power for 5 minutes; faults with a steady red LED can be reset by fixing the issue and pressing the reset button or by turning off the power for 5 minutes.
History: The last three fault codes are recorded in specific parameters along with additional data to assist in troubleshooting. Specific steps using the control panel are followed to clear the fault history.
This summary provides basic information on the fault diagnosis and notification mechanisms of ABB ACS 500 drives, how fault and alarm conditions are displayed, and how faults can be reset.
Error Code 101…199; System Error: There is an error within the drive. Contact your local ABB representative and report the error number.
Error Code 201…299; System Error: There is an error in the system. Contact your local ABB representative and report the error number.
Error Code - UNKNOWN DRIVE TYPE; ACS550: Incorrect panel type, i.e., a panel that supports the X drive but does not support the ACS550, is connected to the ACS550. Be aware of control panel errors and compatibility issues for supported drives.
Error Code 1000; PAR HZRPM: Parameter values are inconsistent. Check for any of the following:
2001 MINIMUM SPEED > 2002 MAXIMUM SPEED.
2007 MINIMUM FREQ > 2008 MAXIMUM FREQ.
2001 MINIMUM SPEED / 9908 MOTOR NOM SPEED not in the proper range (> 50).
2002 MAXIMUM SPEED / 9908 MOTOR NOM SPEED not in the proper range (> 50).
2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ not in the proper range (> 50).
2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ not in the proper range (> 50).
Error Code 1001; PAR PFC REF NEG: Parameter values are inconsistent. Check if 2007 MINIMUM FREQ is negative when 8123 PFC ENABLE is active.
Error Code 1003; PAR AI SCALE: Parameter values are inconsistent. Check for any of the following:
1301 MINIMUM AI1 > 1302 MAXIMUM AI1.
1304 MINIMUM AI2 > 1305 MAXIMUM AI2.
Error Code 1004; PAR AO SCALE: Parameter values are inconsistent. Check for any of the following:
1504 MINIMUM AO1 > 1505 MAXIMUM AO1.
1510 MINIMUM AO2 > 1511 MAXIMUM AO2.
Error Code 1005; PAR PCU 2: Parameter values are inconsistent for power control: Motor nominal kVA or motor nominal power is not appropriate. Perform the following check:
1.1 < (9906 MOTOR NOM CURR · 9905 MOTOR NOM VOLT · 1.73 / PN ) < 3.0, where PN = 1000 · 9909 MOTOR NOM POWER (if units are kW) or PN = 746 · 9909 MOTOR NOM POWER (if units are hp, e.g., in the USA).
Error Code 1006; PAR EXT RO: Parameter values are inconsistent. Check if the expansion relay module is not connected and if 1410…1412 RELAY OUTPUTS 4…6 have non-zero values.
Error Code 1007; PAR FIELDBUS MISSING: Parameter values are inconsistent. A parameter is set for fieldbus control (e.g., 1001 EXT1 COMMANDS = 10 (COMM)), but 9802 COMM PROT SEL = 0 is set. Check and correct the fieldbus settings and connection.
Error Code 1008; PAR PFC MODE: Parameter values are inconsistent – 9904 MOTOR CTRL MODE must be 3 (SCALAR: FREQ) when 8123 PFC ENABLE is activated. Review the motor control mode and PFC settings.
Error Code 1009; PAR PCU 1: Power control parameter values are inconsistent: Motor nominal frequency or speed is not suitable. Check the following:
1 < (60 · 9907 MOTOR NOM FREQ / 9908 MOTOR NOM SPEED) < 16.
0.8 < 9908 MOTOR NOM SPEED / (120 · 9907 MOTOR NOM FREQ / Motor Poles) < 0.992.
Error Code 1012; PAR PFC IO 1: IO configuration is incomplete – Not enough relays parameterized for PFC. Or, a conflict exists between Group 14: RELAY OUTPUTS, parameter 8117 NR OF AUX MOT, and parameter 8118 AUTOCHNG INTERV.
Error Code 1013; PAR PFC IO 2: IO configuration is incomplete – The actual number of PFC motors (parameter 8127, MOTORS) does not match with PFC motors in Group 14: RELAY OUTPUTS and parameter 8118 AUTOCHNG INTERV.
Error Code 1014; PAR PFC IO 3: IO configuration is incomplete – The drive cannot allocate a digital input (interlock) for each PFC motor (parameters 8120 INTERLOCKS and 8127 MOTORS).
Error Code 1016; PAR USER LOAD C: Parameter values are inconsistent for the user load curve. Ensure the following conditions are met:
3704 LOAD FREQ 1 < 3707 LOAD FREQ 2 < 3710 LOAD FREQ 3 < 3713 LOAD FREQ 4 < 3716 LOAD FREQ 5.
3705 LOAD TORQ LOW 1 < 3706 LOAD TORQ HIGH 1.
3708 LOAD TORQ LOW 2 < 3709 LOAD TORQ HIGH 2.
3711 LOAD TORQ LOW 3 < 3712 LOAD TORQ HIGH 3.
3714 LOAD TORQ LOW 4 < 3715 LOAD TORQ HIGH 4.
3717 LOAD TORQ LOW 5 < 3718 LOAD TORQ HIGH 5.
These error codes and suggested solutions continue the list of potential issues and fixes for the ACS 550 drive. By applying the recommended actions for each situation, you can accurately identify and resolve problems.
