Possible cause
Parameter save fault
− faulty operation
− component failure
Values displayed on counters are
incorrect
−
faulty operation
− component failure
Start-up of the drive has been prevented.
Run request in ON when new application
is loaded to the drive
The thermistor input of option board has
detected increase of the motor
temperature
The input on OPTAF board has opened
IGBT Inverter Bridge overtemperature
protection has detected too high a short
term overload current
Cooling fan of the frequency converter
does not start, when ON command is
given
Sent message not acknowledged.
Problem in application software
NXS Control Unit can not control NXP
Power Unit and vice versa
Option board or control unit changed.
Same type of board or same power rating
of drive.
Option board or drive added.
Option board removed.
Unknown option board or drive.
Subcode in T.14:
S1 = Unknown device
S2 = Power1not same type as Power2
IGBT Inverter Bridge overtemperature
protection has detected too high a short
term overload current
Problems with brake resistor.
Problem detected in encoder signals.
Subcode in T.14:
1 = Encoder 1 channel A is missing
2 = Encoder 1 channel B is missing
3 = Both encoder 1 channels are missing
4 = Encoder reversed
5 = Encoder board missing
Correcting measures
Should the fault re-occur, contact the
distributor near to you.
Reset the fault and restart.
Should the fault re-occur, contact the
distributor near to you.
Cancel prevention of start-up if this can
be done safely.
Remove Run request
Check motor cooling and loading
Check thermistor connection
(If thermistor input of the option board is
not in use it has to be short circuited)
Cancel Safe Disable if this can be done
safely.
Check loading.
Check motor size.
Make identification run.
Contact the distributor near to you.
Ensure that there is another device on
the bus with the same configuration.
Contact your distributor. If you are
application programmer check the
application program.
Change control unit
Reset. Device is ready for use.
Old parameter settings will be used.
Reset. Device is ready for use.
Old board settings will be used.
Reset. Device no longer available.
Contact the distributor near to you.
Check loading.
Check motor size.
Make identification run.
Set the deceleration time longer.
Use external brake resistor.
Check encoder channel connections.
Check the encoder board.
Check encoder frequency in open loop.
