ACS150 Drive fault code & solution

Alarm and fault indications
An alarm or fault message on the panel display indicates abnormal drive status.
Using the information given in this chapter most alarm and fault causes can be dentified and corrected. If not, contact an ABB representative.
How to reset
The drive can be reset either by pressing the keypad key on the control panel, through digital input, or by switching the supply voltage off for a while. When the fault
has been removed, the motor can be restarted.
Fault history
When a fault is detected, it is stored in the fault history. The latest faults are stored together with a time stamp.
Parameters 0401 LAST FAULT, 0412 PREVIOUS FAULT 1 and 0413 PREVIOUS FAULT 2 store the most recent faults. Parameters 0404...0409 show drive operation data at the time the latest fault occurred.

Check brake chopper and resistor (if used). DC overvoltage control must be deactivated when brake chopper and resistor are used.
Check deceleration time (2203 and 2206).
Check input power line for static or transient overvoltage.
Retrofit frequency converter with brake chopper and brake resistor.

--------------
F0004 SHORT CIRC
Short circuit in motor cable(s) or motor
Check motor and motor cable.
--------------
F0006 DC UNDERVOLT
Intermediate circuit DC voltage is not sufficient due to missing input power line phase, blown fuse, rectifier bridge internal fault or too low input power.
Check that undervoltage controller is on (parameter 2006 UNDERVOLT CTRL).
Check input power supply and fuses.
--------------
F0007 AI1 LOSS
(programmable fault function 3001, 3021)
Analog input AI1 signal has fallen below limit defined by parameter 3021 AI1 FAULT LIMIT.

Check for proper analog control signal levels.
Check connections.
--------------
F0009 MOT OVERTEMP
(programmable fault function 3005...3009)
Motor temperature is too high (or appears to be too high) due to excessive load, insufficient motor power, inadequate cooling or incorrect start-up data.
Check motor ratings, load and cooling.
Check start-up data.
Check fault function parameter settings.
Let motor cool down. Ensure proper motor cooling:
Check cooling fan, clean cooling surfaces, etc.
--------------
F0012 MOTOR STALL
(programmable fault function 3010 …3012)
Motor is operating in stall region due to e.g. excessive load or insufficient motor power.
Check motor load and drive ratings.
Check fault function parameter settings.
--------------
F0014 EXT FAULT 1
(programmable fault function 3003)
External fault 1 Check external devices for faults.
Check fault function parameter setting.
--------------
F0015 EXT FAULT 2
(programmable fault function 3004)
External fault 2 Check external devices for faults.
Check fault function parameter setting.
--------------
F0016 EARTH FAULT
(programmable fault function 3017)
Drive has detected earth (ground) fault in motor or motor cable.
Check motor.
Check fault function parameter setting.
Check motor cable. Motor cable length must not exceed maximum specifications.
See section Motor connection on page 119.
--------------
F0017 UNDERLOAD
(programmable fault function 3013...3015)
Motor load is too low due to e.g. release mechanism in driven equipment.
Check for problem in driven equipment.
Check fault function parameter settings.
Check motor power against unit power.
--------------
F0018 THERM FAIL
Drive internal fault. Thermistor used for drive internal temperature measurement is open or short-circuited.
Contact our Abb product representative (contact information available on the Abb homepage). .
--------------
F0021 CURR MEAS
Drive internal fault. Current measurement is out of range.
Contact our Abb product representative (contact information available on the Abb homepage). .
--------------
F0022 INPUT PHASE LOSS
(programmable fault function 3016)
Intermediate circuit DC voltage is oscillating due to missing input power line phase or blown fuse.
Fault trip occurs when DC voltage ripple exceeds 14% of nominal DC voltage.
Check input power line fuses.
Check for input power supply imbalance.
Check fault function parameter setting.
--------------
F0026 DRIVE ID Internal drive ID fault Contact our Abb product representative (contact information available on the Abb homepage). .
--------------
F0027 CONFIG FILE Internal configuration file error Contact our Abb product representative (contact information available on the Abb homepage). .
--------------
F0035 OUTP WIRING
(programmable fault function 3023)
Incorrect input power and motor cable connection (i.e. input power cable is connected to drive motor connection).
Check input power connections.
Check fault function parameter setting.
--------------
F0036 INCOMPATIBLE SW
Loaded software is not compatible.
Contact our Abb product representative (contact information available on the Abb homepage). .
--------------
F0101 SERF CORRUPT Corrupted Serial Flash chip file system
F0103 SERF MACRO Active macro file missing from Serial Flash chip

--------------
F1000 PAR HZRPM
Incorrect speed/frequency limit parameter setting
Check parameter settings. Following must apply: 2007 < 2008,
2007/9907 and 2008/9907 are within range.
--------------
F1003 PAR AI SCALE
Incorrect analog input AI signal scaling
Check parameter group 13 ANALOG INPUTS settings. Following must apply: 1301 < 1302.
--------------
Fan repair
The drive’s cooling fan has a life span of minimum 25 000 operating hours. The actual life span depends on the drive usage and ambient temperature.
Fan failure can be predicted by the increasing noise from the fan bearings. If the drive is operated in a critical part of a process, fan replacement is recommended once these symptoms start appearing. Replacement fans are available from ABB.
Do not use other than ABB specified spare parts. Contact our Abb product representative (contact information available on the Abb homepage).
