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
