ACS 355 Fault Codes 3
Hi everyone,
Fault and alarm indicators in ABB ACS355 drives are designed to indicate abnormal conditions of the drive. A red LED indicates a fault, and an alarm or fault message on the control panel signifies that the drive is in an abnormal condition. Using the information provided in this section, most alarm and fault causes can be identified and corrected. If the issue is not resolved, contact an ABB representative.
Fault Codes
Fault codes are indicated in parentheses with a four-digit code number for field communication. For more information on field communication, refer to the "Field Communication Control with Embedded Field Communication" (page 301) and "Field Communication Control with Field Communication Adapter" (page 325) sections.
Fault Reset Methods
The drive can be reset by pressing a button on the basic control panel or via the (assistant control panel), through a digital input or field communication, or by turning off the supply voltage for a while. The source of the fault reset signal is selected with the 1604 FAULT RESET SEL parameter. After the fault is cleared, the motor can be restarted.
Fault History
When a fault is detected, it is stored in the fault history. The latest faults are stored with a timestamp. Parameters 0401 LAST FAULT, 0412 PREVIOUS FAULT 1, and 0413 PREVIOUS FAULT 2 store the latest faults. Parameters 0404…0409 show the operating data of the drive when the latest fault occurred. The assistant control panel provides additional information about the fault history. For more information, see the "Fault Logger Mode" section (page 101).
These features and functions are critical for the effective monitoring and management of ABB drives. If you encounter an issue with your drive, you can use this information to identify the problem and evaluate potential solutions. When technical support or more detailed assistance is needed, it is important to contact ABB's technical support.
Fault Codes, Causes, and Actions
Fault Code 0030: Forced Stop (FF90)
A stop command has been received from field communication. Refer to the relevant communication module manual.
Fault Code 0034: Motor Phase (FF56)
A motor circuit fault due to a missing motor phase or a fault in the motor thermistor relay (used for motor temperature measurement). Check the motor and motor cable. Check the motor thermistor relay (if used).
Fault Code 0035: Output Wiring (FF95)
Incorrect input power and motor cable connection (i.e., the input power cable is connected to the drive motor connection). The fault may be falsely declared if the drive is faulty or if the input power is in a delta grounded system and the motor cable capacitance is large. Check the input power connections.
Fault Code 0036: Incompatible Software (630F)
The loaded software is not compatible. Contact your local ABB representative.
Fault Code 0037: Control Board Overtemperature (4110)
The drive control board has overheated. The fault trigger limit is 95 °C. Check for excessive ambient temperature. Check for fan failure. Check for obstructions in airflow. Check the cabinet sizing and cooling.
Fault Code 0044: Safe Torque Off (FFA0)
STO (Safe Torque Off) has been requested and is functioning correctly. The 3025 STO OPERATION parameter is set to respond with a fault. If this response to the disconnection of the safety circuit is not expected, check the wiring of the safety circuit connected to terminals X1C. If a different response is required, change the value of the 3025 STO OPERATION parameter. Reset the fault before starting.
Fault Code 0045: STO1 Loss (FFA1)
STO (Safe Torque Off) input channel 1 is not de-energized, but channel 2 is de-energized. The opening contacts in channel 1 may be damaged or short-circuited. Check the wiring of the STO circuit and the opening of contacts in the STO circuit.
Fault Code 0046: STO2 Loss (FFA2)
STO (Safe Torque Off) input channel 2 is not de-energized, but channel 1 is de-energized. The opening contacts in channel 2 may be damaged or short-circuited. Check the wiring of the STO circuit and the opening of contacts in the STO circuit.
Internal Faults and Configuration Issues
Fault Code 0101: SERF Corrupted (FF55)
Internal drive fault. Write down the fault code and contact your local ABB representative.
Fault Code 0103: SERF Macro (FF55)
Internal drive fault. Write down the fault code and contact your local ABB representative.
Fault Code 0201: DSP T1 Overload (6100)
DSP T1 is overloaded. Contact your local ABB representative.
Fault Code 0202: DSP T2 Overload (6100)
DSP T2 is overloaded. Contact your local ABB representative.
Fault Code 0203: DSP T3 Overload (6100)
DSP T3 is overloaded. Contact your local ABB representative.
Fault Code 0204: DSP Stack Error (6100)
DSP stack error. Contact your local ABB representative.
Fault Code 0206: CB ID Error (5000)
Control board identity error. Contact your local ABB representative.
Parameter Setting Errors
Fault Code 1000: PAR HZRPM (6320)
Incorrect speed/frequency limit parameter setting. Check the parameter settings and ensure the following are applied:
2001 MINIMUM SPEED < 2002 MAXIMUM SPEED
2007 MINIMUM FREQ < 2008 MAXIMUM FREQ
Ensure the values of 2001 MINIMUM SPEED / 9908 MOTOR NOM SPEED, 2002 MAXIMUM SPEED / 9908 MOTOR NOM SPEED, 2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ, and 2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ are within range.
Fault Code 1003: PAR AI Scaling (6320)
Incorrect analog input AI signal scaling. Check the settings of the 13 ANALOG INPUTS parameter group and ensure the following are applied:
1301 MINIMUM AI1 < 1302 MAXIMUM AI1
1304 MINIMUM AI2 < 1305 MAXIMUM AI2
Fault Code 1004: PAR AO Scaling (6320)

Fault Code 1017: PAR SETUP 1 (6320)
Only two of the following can be used simultaneously: MTAC-01 encoder module, frequency input signal, or frequency output signal. Disable either the frequency output, frequency input, or encoder:
Change the transistor output to digital mode (1804 TO MODE parameter value = 0 [DIGITAL]),
Change the frequency input selection to another value in the 11 REFERENCE SELECT, 40 PROCESS PID SET 1, 41 PROCESS PID SET 2, and 42 EXT / TRIM PID parameter groups,
Disable (5002 ENCODER ENABLE parameter) and remove the MTAC-01 encoder module.
