WARNING 1

Under 10 Volts (10 VOLT LOW):

The 10 Volts voltage from terminal 50 on the control card is below 10 Volts.

Remove some of the load from terminal 50, as the 10

Volts supply is overloaded. Max. 17 mA/min. 590 .

WARNING/ALARM 2

Live zero fault (LIVE ZERO ERROR):

The current signal on terminal 60 is less than 50% of the value set in parameter 315

Terminal 60,min. scaling.

WARNING/ALARM 3

No motor (NO MOTOR):

The motor check function (see parameter 122) indicates that no motor has been connected to the output of the frequency converter.

WARNING/ALARM 4

Phase fault (MAINS PHASE LOSS):

A phase is missing on the supply side or the mains voltage imbalance is too high.

This mesage can also appear if there is a fault in the input rectifier on the frequency converter.

Check the supply voltage and supply currents to the frequency converter.

WARNING 5

Voltage warning high

(DC LINK VOLTAGE HIGH):

The intermediate circuit voltage (DC) is higher than the overvoltage limit of the control system. The frequency converter is still active.

WARNING 6

Voltage warning low (DC LINK VOLTAGE LOW):

The intermediate circuit voltage (DC) is below the undervoltage limit of the control system. The frequency converter is still active.

WARNING/ALARM 7

Overvoltage (DC LINK OVERVOLT):

If the intermediate circuit voltage (DC) exceeds the inverter overvoltage limit (see table), the frequency converter will trip.

Furthermore, the voltage will be stated in the display. The fault can be eliminated by connecting a brake resistor (if the frequency converter has an integral brake chopper, EB or SB). In addition,

Brake function/overvoltage control

can be activated in parameter 400.

Undervoltage (DC LINK UNDERVOLT):

If the intermediate circuit voltage (DC) drops below the inverter lower voltage limit (see table on previous page), it will be checked whether

24 V power supply is connected.

If no 24 V power supply is connected, the frequency converter will trip after a given time that depends on the unit.

Furthermore, the voltage will be stated in the display.

Check whether the supply voltage matches the frequency converter, see technical data.

WARNING/ALARM 9

Inverter overload (INVERTER TIME):

The electronic, thermal inverter protection reports that the frequency converter is about to cut out because of an overload (too high current for too long). The counter for electronic, thermal inverter protection gives a warning at 98% and trips at 100%, while giving an alarm. The frequency converter cannot be reset until the counter is below 90%.

The fault is that the frequency converter is overloaded by more than 100% for too long.

WARNING/ALARM 10

Motor overtemperature (MOTOR TIME):

According to the electronic thermal protection (ETR), the motor is too hot. Parameter 128 allows a choice of whether the frequency converter is to give a warning or an alarm when the counter reaches 100%. The fault is that the motor is overloaded by more than

100% for too long. Check that motor parameters

102-106 have been set correctly.

WARNING/ALARM 11

Motor thermistor (MOTOR THERMISTOR):

The thermistor or the thermistor connection has been disconnected. Parameter 128 allows a choice of whether the frequency converter is to give a warning or an alarm. Check that the thermistor has been correctly connected between terminal 53 or 54 (analog voltage input) and terminal 50 (+ 10 Volts supply).

WARNING/ALARM 12

Torque limit (TORQUE LIMIT):

The torque is higher than the value in parameter 221

(in motor operation) or the torque is higher than the value in parameter 222 (in regenerative operation).

WARNING/ALARM 13

Overcurrent (OVERCURRENT):

The inverter peak current limit (approx. 200% of the rated current) has been exceeded. The warning will last approx. 1-2 seconds, following which the frequency converter will trip, while giving an alarm.

WARNING 23

VLT

®

5000 FLUX

Fault during brake test (BRAKE TEST FAILED):

The brake test is only run after power-up. If

Warning

has been selected in parameter 404, the warning will come when the brake test finds a fault.

The brake test may fail for the following reasons:

No brake resistor connected or fault in the connections; defective brake resistor or defective brake transistor. A warning or alarm will mean that the brake function is still active.

WARNING 25

Brake resistor fault

(BRAKE RESISTOR FAULT):

The brake resistor is monitored during operation and if it short-circuits, the brake function is disconnected and the warning comes up. The frequency converter will still be able to work, although without the brake function. Turn off the frequency converter and replace the brake resistor.

ALARM/WARNING 26

Brake resistor power 100%

(BRAKE PWR WARN 100%):

The power transmitted to the brake resistor is calculated as a percentage, as a mean value over the last 120 sec., on the basis of the resistance value of the brake resistor (parameter 401) and the intermediate circuit voltage. The warning is active when the dissipated braking power is higher than 100%. If

Trip

[2] has been selected in parameter 403, the frequency converter will cut out while giving this alarm.

WARNING 27

Brake transistor fault

(BRAKE IGBT FAULT):

The brake transistor is monitored during operation and if it short-circuits, the brake function is disconnected and the warning comes up. The frequency converter will still be able to run, but since the brake transistor has short-circuited, substantial power will be transmitted to the brake resistor, even if it is inactive.

Turn off the frequency converter and remove the brake resistor.

Warning: There is a risk of substantial power being transmitted to the brake resis- tor if the brake transistor has short-circuited.

ALARM: 29

Heat sink temperature too high

(HEAT SINK OVER TEMP.):

If the enclosure is IP 00 or IP 20, the cut-out temperature of the heat-sink is 90°C. If IP 54 is used, the cut-out temperature is 80°C.

MG.55.A6.02 — VLT is a registered Danfoss trademark

127

The tolerance is ± 5°C. The temperature fault cannot be reset, until the temperature of the heat-sink is below 60°C.

The fault could be the following:

— Ambient temperature too high

— Too long motor cable

ALARM: 30

Motor phase U missing

(MISSING MOT.PHASE U):

Motor phase U between frequency converter and motor is missing.

Turn off the frequency converter and check motor phase U.

ALARM: 31

Motor phase V missing

(MISSING MOT.PHASE V):

Motor phase V between frequency converter and motor is missing.

Turn off the frequency converter and check motor phase V.

ALARM: 32

Motor phase W missing

(MISSING MOT.PHASE W):

Motor phase W between frequency converter and motor is missing.

Turn off the frequency converter and check motor phase W.

WARNING/ALARM: 34

Profibus communication fault

(PROFIBUS COMMUNICATION FAULT):

The profibus on the communication option card is not working.

WARNING: 35

Out of speed range

(OUT OF SPEED RANGE):

This warning is active if the output frequency has reached its

Output speed low limit

(parameter 201) or

Output speed high limit

(parameter 202).

WARNING/ALARM: 36

Mains failure (MAINS FAILURE):

This warning/alarm is only active if the supply voltage to the frequency converter is lost and if parameter 407

Mains fault

has been set to another value than

OFF

.

If parameter 407 has been set to

Contr. ramp-down trip

[2], the frequency converter will first give a warning and then ramp down and trip, while giving an alarm.

Check the fuses to the frequency converter.

ALARM: 37

Inverter fault (Inverter fault):

VLT

®

5000 FLUX

IGBT or the power card is defective. Contact your Danfoss supplier.

Auto-optimisation warnings

A choice must thus be made by pressing [CHANGE

DATA] and choosing ‘Continue ’ + [OK] or ‘Stop ’ + [OK].

If parameters need to be changed, select

‘Stop ’ ; start up AMA all over.

WARNING: 39

CHECK P.104,106

The setting of parameter 102, 104 or 106 is probably wrong. Check the setting and choose ‘Continue ’ or ‘Stop ’ .

WARNING: 40

CHECK P.103,105

The setting of parameter 102, 103 or 105 is probably wrong. Check the setting and choose ‘Continue ’ or ‘Stop ’ .

WARNING: 41

MOTOR TOO BIG

The motor used is probably too big for AMA to be carried out. The setting in parameter 102 may not match the motor. Check the motor and choose ‘Continue

’ or ‘Stop

’

.

WARNING: 42

MOTOR TOO SMALL

The motor used is probably too small for AMA to be carried out. The setting in parameter 102 may not match the motor. Check the motor and choose ‘Continue ’ or ‘Stop ’ .

ALARM: 43

Brake fault (BRAKE FAULT)

A fault has arisen on the brake. The text shown in the display indicates a fault message. The figure after the text is the fault code that can be seen in the fault log, parameter 615.

Brake check failed (BRAKE CHECK FAILED) [0]

The brake check carried out during power-up indicates that the brake has been disconnected. Check whether the brake has been connected correctly and that it has not been disconnected.

Brake resistor short-circuited

(BRAKE RESISTOR FAULT) [1]

The brake output has short-circuited. Replace the brake resistor.

Brake IGBT short-circuited

128

MG.55.A6.02 — VLT is a registered Danfoss trademark

(BRAKE IGBT FAULT) [2]

The brake IGBT has short-circuited. This fault means that the unit is not able to stop the brake and that, consequently, the resistor is constant being energized.

WARNING/ALARM: 44

Encoder loss (ENCODER FAULT)

The encoder signal is interrupted from terminal

32 or 33. Check the connections.

LEDs on encoder board:

When all LEDs are ON the connection to encoder and encoder condition are OK.

LED 403 OFF: 5 V supply missing

LED 400 OFF: Channel A or inv. A missing or shortcircuited

LED 401 OFF: Channel B or inv. B missing or shortcircuited

LED 402 OFF: Channel Z or inv. Z missing or shortcircuited.

ALARM 48:

Tracking fault

The following events can generate Alarm 48:

•

Parameter 361 set too low: Extend the range

•

Wrong encoder direction: Motor goes one way, the encoder goes the other way

•

Running in torque limit: Insufficient torque to follow the ramp, hitting an obstruction, etc.

•

Bad PID settings: Oscillations can produce large errors. Readjust the PID control

(Parameters 417 and 418)
