Fault
code Fault Name Fault Type Default Possible Cause Remedy Realization
12
Brake Chopper Superv Fault
•
No brake resistor installed
•
Brake resistor is broken
•
Brake chopper failure
Check brake resistor and cabling. If these
are OK, the chopper is faulty. Contact the
distributor near you
DSP
13
Drive UnderTemp Configurable Warning
•
Too low temperature measured
in power
•
Unit’s heat sink or board. Heat
sink temperature is under –10°C
DSP
14
Drive OverTemp Fault
•
Too high temperature measured
in power
•
Unit’s heat sink or board. Heat
sink temperature is over 90°C
•
Check the correct amount and flow of
cooling air
•
Check the heat sink for dust
•
Check the ambient temperature
•
Make sure that the switching frequency
is not too high in
relation to ambient temperature and
motor load
DSP
15
Motor Stalled Configurable No Action Motor is stalled Check motor and load DSP
16
Motor Over Temp Configurable No Action Motor is too hot, based on
either the drive’s estimate or on
temperature feedback
Decrease motor load. If no motor
overload exists, check the temperature
model parameters
DSP
17
Motor Under Load Configurable No Action Condition defined by parameter
P6.1.11-P6.1.13 have been
valid longer than the time
defined by P6.1.14
Check load DSP
18
IP Address Conflict Configurable Warning IP setting issue. Check settings for IP address, verify no
duplicates are on the network.
MCU
19
Power Board
EEPROM Fault
Fault Power board eeprom fault, memory
lost in eeprom.
Cycle power to drive. Try updating
software, if issue continues contact
Distributor near you.
MCU
20
FRAM Fault Fault FRAM data error in FRAM memory. Cycle power to drive. Try updating
software, if issue continues contact a
Distributor near you.
MCU
21
S-Flash Fault Warning Serial flash error, serial flash
memory failed.
Cycle power to drive. Try updating
software, if issue continues contact a
Distributor near you.
MCU
25
MCU Watchdog Fault Fault Watchdog register overflows
in MCU
Cycle power to drive. Try updating
software, if issue continues contact a
Distributor near you.
MCU
26
Start-up Prevent Fault The time when Interlock signal
activates is over setting time.
Stop drive and resend start command. MCU
29
Thermistor Fault Configurable Fault Option board or control board
thermistor resistor lager than 4.7K
Thermistor open or short, over
temperature
MCU
32
Fan Cooling Fault Fan is damaged or stalled. Check fan and fan connected wires, verify
24Vdc is supplied to fan.
DSP
36
Compatibility Fault Fault The control board isn’t match with
the power board.
Cycle power to drive. Try updating
software, if issue continues contact a
Distributor near you.
MCU
37
Device Change Warning Power board or option card change. Alarm will reset MCU
38
Device Added Warning Power board or option board added.
•
Device is ready for use
•
Old parameter settings will be used
MCU
39
Device Removed Fault Optional board removed from slot,
or power board removed from
control board.
Device no longer available in drive. MCU
40
Device Unknown Fault Unknown device connected (power
board/option board)
•
Check eeprom connection.
•
Check board connection on slot A/B
•
Power cycle to drive.
MCU
41
IGBT Over Temp Fault IGBT temperature is too high.
•
Check output loading
•
Check motor size
•
Decrease switching frequency
DSP
50
AI < 4mA (4to20mA) Configurable No Action Loss in analog input signal, dropped
below 4mA.
Verify analog input current
reference value on either AI1 or AI2,
check cabling.
MCU
51
External Fault Configurable Fault Digital input is activated for
external fault input.
Check digital input settings and verify
input level, could be an external device
causing fault.
