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 NXP 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 NXS control board.
F9 Undervoltage 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 = Undervoltage control supervision
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.
