8 UnderVoltage Configurable
1
Fault DC link voltage is under the voltage limits
defined:
• Most probable cause: Too low a supply
voltage
• AC drive internal fault
• Defect input fuse
• External charge switch not closed
Note: This fault is activated only if the drive is
in Run state.
In case of temporary supply voltage break
reset the fault and restart the AC drive
Check the supply voltage. If it is adequate,
an internal failure has occurred. Contact
the distributor near you
9 Input Phase Spv Configurable
1
No Action Input line phase is missing Check supply voltage, fuses and cable
10 Output Phase Spv Configurable
1
Fault Current measurement has detected that there
is no current in one motor phase
Check motor cable and motor
11 BrakeChopperSpv 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
12 Drive UnderTemp Configurable
1
Warning Too low temperature measured in power
Unit’s heat sink or board. Heat sink
temperature is under –10°C
13 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
14 Motor Stalled Configurable
1
No Action Motor is stalled Check motor and load
15 Motor OverTemp Configurable
1
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
16 Motor UnderLoad Configurable
1
No Action Condition defined by parameter
P1.9.15~P1.9.17 have been valid longer than
the time defined by P1.9.18
Check load
17 IP Address Conflict Configurable Warning Reversed
18 Power board
EEPROM Fault
Fault Power board eeprom fault Check eeprom
19 FRAM Fault Fault Fram data error Check fram
20 Serial Flash Fault Fault Serial flash error Check serial flash
21 MCU Watchdog Fault Fault Watchdog register overflows Power cycle unit
22 Start-up Prevent Fault The time when Interlock signal activates is
over setting time
Stop drive
23 Thermistor Fault Configurable
1
Fault Option board or control board thermistor
resistor lager than 4.7K
Thermistor open or short, over
temperature
24 Fan Cooling Fault Fan is damaged or stalled Check fan and fan connected wires
25 Compatibility Fault Fault The control board isn’t match with the power
board
Contact the distributor near you
26 Device Change Warning Power board or option card change
27 Device Added Warning Power board or option board added
The option board was previously inserted
in the same slot. The board’s parameter
settings are saved
Device is ready for use
Old parameter settings will be used
