System fault

-

component failure

- faulty operation

Note exceptional fault data record

Subcode in T.14:

S1 = Feedback of motor voltage

S2 = Reserved

S3 = Reserved

S4 = ASIC trip

S5 = Disturbance in VaconBus

S6 = Feedback of charging switch

S7 = Charging switch

S8 = No power to driver card

S9 = Power unit communication (TX)

S10 = Power unit communication (Trip)

S11 = Power unit comm. (Measurement)

Reset the fault and restart.

Should the fault re-occur, contact your

local distributor.

9

Undervoltage

DC

-

link voltage is under the voltage

limits defined in Table 4-5.

 most probable cause: too low a

supply voltage

 frequency converter internal fault

Subcode in T.14:

S1 = DC-link too low during run

S2 = No data from power unit

S3 = Undervoltage control supervision

In case of temporary supply voltage

break, reset the fault and restart the

frequency converter. Check the supply

voltage. If it is adequate, an internal

failure has occurred.

Contact your local distributor.

10

Input line

supervision

Input line phase is missing.

Subcode in T.14:

S1 = Phase supervision diode supply

S2 = Phase supervision active front end

Check supply voltage, fuses and cable.

11

Output phase

supervision

Current measurement has detected that

there is no current in one motor phase.

Check motor cable and motor.

12

Brake chopper

supervision

 no brake resistor installed

 brake resistor is broken

 brake chopper failure

Check brake resistor and cabling.

If ok, the chopper is faulty. Contact your

local distributor.

13

Frequency con

-

verter under-

temperature

Heatsink temperature is under –10C

14

Frequency con

-

verter over-

temperature

Heatsink temperature is over 90C

Overtemperature warning is issued

when the heatsink temperature exceeds

85C.

S1 = Measurement

S2 = Internal thermistor

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.

15

Motor stalled

Motor stall protection has tripped.

Check motor and load.

16

Motor over

-

temperature

Motor overheating has been detected by

frequency converter motor temperature

model. Motor is overloaded.

Decrease the motor load.

If no motor overload exists, check the

temperature model parameters.

17

Motor

underload

Motor underload protection has tripped.

Check load.
