F8 System fault
A system fault indicates several different fault situations in
drive operation.
S1 = Reserved
•
Disturbance. Reset the unit and try again
•
If there is star coupler in the unit, check the fibre
connections and phase order
•
Driver board or IGBT broken
•
FR9 and the bigger size drives, which includes not star
coupler, ASIC board (VB00451) is broken
•
FR8 and smaller size drives: control board broken
•
FR8 and smaller size drives: if there is boardsVB00449/
VB00450 in use, failure might be in there
S2 = Reserved
S3 = Reserved
S4 = Reserved
S5 = Reserved
S6 = Reserved
S7 = Charge switch
S8 = No power to driver card
S9 = Power unit communication (TX)
S10 = Power unit communication (Trip)
S11 = Power unit comm. (Measurement)
S12 = SystemBus synchronization has failed in
DriveSynch operation
S30 = Safe disable inputs are in different state (OPT-AF)
S31 = Thermistor short circuit detected (OPT-AF)
S32 = OPT-AF board has been removed
S33 = OPT-AF board EEPROM eror
S34-36 = OPT-AF supply voltage hardware problem detected.
S37-40 = Single hardware problem detected in STO inputs.
S41-43 = Single hardware problem detected in the
thermistor input.
S44-46 = Single hardware problem detected in STO inputs
or in the thermistor input.
S47 = OPT-AF board mounted in old SPX control board.
S48 = Parameter Expander boards/SlotB/Therm Trip(HW) is
set to OFF even if the jumper wire X12 is not cut.
S49 = OPT-AF board mounted in SVX control board.
F9 Under voltage fault
DC-link voltage is below the fault voltage limit of the drive.
S1 = DC-link too low during run
S2 = No data from power unit
S3 = Under voltage controller has been active and speed is
ramped to zero with ramp time 2.
Possible cause
1.
Too low a supply voltage
2.
Frequency converter internal fault
3.
One of the input fuses is broken
4.
External charge switch has not been closed
Correcting measures
•
In case of temporary supply voltage break, reset the fault
and restart the frequency converter
•
Check supply voltage
•
Check function of DC charge
•
Contact your local distributor
F10 Input line supervision
S1 = Phase supervision diode supply
S2 = Phase supervision active front end
Possible cause:
1.
Input line phase is missing
Correcting measures
•
Check supply voltage, fuses and cable
F11 Output phase supervision
Current measurement has detected that there is no current
in one phase or one phase current is considerably different
from other phases.
Correcting measures
•
Check motor cable and motor
F12 Brake chopper supervision
Brake chopper supervision generates pulses to the brake
resistor for response. If no response is received within set
limits a fault is generated.
Possible cause:
1.
No brake resistor installed
2.
Brake resistor is broken
3.
Brake chopper failure
4.
Correcting measures:
•
Check brake resistor and cabling
•
If these are ok the chopper is faulty. Contact your
local distributor
