Fault

code

Fault

Possible cause

Correcting measures

Brake chopper
supervision

no brake resistor installed
brake resistor is broken

brake chopper failure

Check brake resistor.
If the resistor is ok, the chopper is

faulty. Contact the nearest Vacon

distributor.

Inverter

undertemperature

Heatsink temperature is under –10 C

Inverter
overtemperature

Heatsink temperature is over 90 C or

77ºC (NX_6, FR6).

Overtemperature warning is issued
when the heatsink temperature exceeds
85 C (72ºC).

Check the correct amount and flow of
cooling air.

Check the heatsink for dust.

Check the ambient temperature.
Make sure that the switching frequency

is not too high in relation to ambient
temperature and motor load.

Motor stalled

Motor stall protection has tripped.

Check motor.

Motor over-

temperature

Motor overheating has been detected by

inverter motor temperature model.
Motor is overloaded.

Decrease the motor load.

If no motor overload exists, check the
temperature model parameters.

Motor underload

Motor underload protection has tripped.

Unbalance

Unbalance between power modules in

parallelled units.
Subcode in T.14:

S1 = Current unbalance

S2 = DC voltage unbalance

Should the fault re-occur, contact the

distributor near to you.

EEPROM
checksum fault

Parameter save fault
faulty operation

component failure

Counter fault

Values displayed on counters are

incorrect

Microprocessor

watchdog fault

faulty operation

component failure

Reset the fault and restart.

Should the fault re-occur, contact the
distributor near to you.

Start-up
prevented

Start-up of the drive has been
prevented.

Cancel prevention of start-up.

Thermistor fault

The thermistor input of option board has
detected increase of the motor

temperature

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)

Safe disable

The input on OPTAF board has opened

Cancel Safe Disable if this can be done
safely.

IGBT temperature
(hardware)

IGBT Inverter Bridge overtemperature
protection has detected too high a short

term overload current

Check loading.
Check motor size.

Fan cooling

Cooling fan of the inverter does not

start, when ON command is given

Contact the nearest Vacon distributor.

CAN bus

communication

Sent message not acknowledged.

Ensure that there is another device on

the bus with the same configuration.

Application

Problem in application software.

Contact your distributor. If you are

application programmer check the
application program.

Control unit

NXS Control Unit can not control NXP
