Troubleshooting and Maintenance
Fault/Alarm Description Possible Causes
A050:
IGBT High Temperature U A high temperature alarm was detected by the NTC
temperature sensors located on the IGBTs.
Note:
It may be disabled by setting P0353 = 2 or 3.
;
Surrounding air temperature is too high (> 40 °C
or 45 °C (104 °F or 113 °F) depending on the
converter model - refer to item 3.1) and output
current is too high.
; Blocked or defective fan.
;
Very dirty heatsink.
F051:
IGBT Overtemperature U Overtemperature fault on the IGBTs of phase U.
A053:
High Temperature on IGBTs V Alarm of high temperature measured at the temperature
sensors (NTC) of the IGBTs.
Note:
It can be disabled by setting P0353 = 2 or 3.
F054:
Overtemperature on IGBTs V Overtemperature fault on the IGBTs of phase V.
A056:
High Temperature on
IGBTs W Alarm of high temperature measured at the temperature
sensors (NTC) of the IGBTs.
Note:
It can be disabled by setting P0353 = 2 or 3.
F057:
Overtemperature on IGBTs W Overtemperature fault on the IGBTs of phase W.
F070:
Overcurrent /Short-circuit Overcurrent or short-circuit detected at the input,
DC link. ; IGBT modules are shorted.
F071:
Input Overcurrent The converter input current was too high for too long.
;
Input reactance too low.
;
P0169 and P0170 settings are too high.
F074:
Ground Fault A ground fault occured.
Note:
It may be disabled by setting P0343 = 0.
;
+UD or -UD short-circuit to ground.
F080:
CPU Watchdog Microcontroller watchdog fault.
;
Electrical noise.
F082:
Copy Function Fault Fault while copying parameters.
;
An attempt to copy the keypad parameters to
an converter with a different firmware version.
F084:
Auto-diagnosis Fault Auto-diagnosis Fault.
;
Defect in the converter internal circuitry.
A088:
HMI Communication Lost Indicates a problem with the keypad and control board
communication.
;
Loose keypad cable connection.
;
Electrical noise in the installation.
A090:
External Alarm External alarm via digital input.
Note:
It is required to set a digital input to “No external alarm”.
; Wiring was not connected to the digital input
(DI1 to DI8) set to “No external alarm”.
F091:
External Fault External fault via digital input.
Note:
It is required to set a digital input to “No external fault”.
;
Wiring was not connected to the digital input
(DI1 to DI8) set to “No external fault”.
F099:
Invalid Current Offset Current measurement circuit is measuring a wrong
value for null current.
;
Defect in the converter internal circuitry.
F101:
Invalid Voltage Offset Offset calculation error when reading the input voltage
(synchronism).
;
Main contactor closed before the pre-charge
is complete.
;
CPU has reset and the main contactor did not open.
A105:
Reactive Injection in the Power
Supply Alarm for the reactive current injection in the power
supply.
;
Voltage power supply much higher than the
rated voltage.
; P0180 too low.
F151:
FLASH Memory Module Fault FLASH Memory Module fault (MMF-01). ; Defective FLASH memory module.
;
Check the connection of the FLASH memory
module.
A152:
Internal Air High Temperature Alarm indicating that the internal air temperature is too
high.
Note:
It may be disabled by setting P0353 = 1 or 3.
;
Surrounding air temperature too high (>40 °C or
50 °C (104 °F or 122°F) according to the model
- refer to item 3.1) and excessive output current.
;
Blocked or defective fan.
;
Fins of the book heatsink too dirty, impairing
the air flow.
F153:
Internal Air Overtemperature Internal air overtemperature fault.
F156:
Undertemperature Undertemperature fault below -30 °C (-22 °F) in the
IGBTs or rectifier measured by the temperature sensors. ; Surrounding air temperature ≤ -30 °C (-22 °F).
;
Defective internal circuitry of the power modules
(supply, cables).
A177:
Fan Replacement Fan replacement alarm (P0045 > 50000 hours).
Note:
This function may be disabled by setting P0354 = 0.
;
Maximum number of operating hours for the
heatsink fan has been reached.
F179:
Heatsink Fan Speed Fault Fan speed is under the minimum limit. ; The fan is dirt or blocked.
A181:
Invalid Clock Value Invalid clock value alarm. ; It is necessary to set date and time at parameters
P0194 to P0199.
;
Keypad battery is discharged, defective, or not
installed.
