NOTE 1

Overcurrent

The inverter peak current limit

(approximately 200% of the rated current)

is exceeded. The warning lasts

approximately 1.5 s, then the frequency

converter trips and issues an alarm. Shock

loading or quick acceleration with high-

inertia loads can cause this fault. If the

acceleration during rampup is quick, the

fault can also appear after kinetic back-up.

If extended mechanical brake control is

selected, a trip can be reset externally.

• Remove the power and check if the motor

shaft can be turned.

• Check that the motor size matches the fre

quency converter.

• Check that the motor data is correct in param

eters 1–20 to 1–25.

014

NOTE 1

Ground Fault

There is current from the output phase to

ground, either in the cable between the

frequency converter and the motor or in the

motor itself. This fault is detected during

motor operation.

• Remove power to the frequency converter and

repair the ground fault.

• Check for ground faults in the motor by mea

suring the resistance to ground of the motor

cables and the motor with a megohmmeter.

015

Alarm

Hardware

Mismatch

A fitted option is not operational with the

present control board hardware or software

Record the value of the following parameters and

contact Danfoss:

• 15-40 FC Type

• 15-41 Power Section

• 15-42 Voltage

• 15-43 Software Version

• 15-45 Actual Typecode String

• 15-49 SW ID Control Card

• 15-50 SW ID Power Card

• 15-60 Option Mounted

• 15-61 Option SW Version (for each option

slot)

016

Alarm

Short Circuit

There is short-circuiting in the motor or

motor wiring

• Remove the power to the frequency converter

and repair the short circuit

017

NOTE 1

Control Word

Timeout (Serial

Communication

Failure)

There is no communication to the

frequency converter. The warning is only

active when 8-04 Control Word Timeout

Function is NOT set to [0] Off. If 8-04

Control Word Timeout Function is set to [5]

Stop and Trip, a warning appears and the

frequency converter ramps down until it

stops, and then it displays an alarm

Check the connections on the serial

communications cables including the shields and

termination resistors.

Warning

Internal Fan

Fault

Monitors operation of the internal cooling

fan

Check for proper fan operation, cycle power to

VFD and confirm that fan operates at startup

029

NOTE 1

Heat Sink

Overtemperature

The maximum temperature of the heat sink

has been exceeded. The temperature fault

does not reset until the temperature drops

below a defined heat sink temperature. The

trip and reset points are different based on

the frequency converter power size

• Ambient temperature too high.

• Motor cables too long.

• Incorrect airflow clearance above and below

the frequency converter.

• Blocked airflow around the frequency

converter.

• Damaged heat sink fan.

• Dirty heat sink.

converter and the motor is missing

Remove the power from the frequency converter

NOTE 1

Fieldbus

Communication

Fault

The fieldbus on the communication option

card is not working

Check the communication wiring connections,

including the shield. Check the termination

resistors.

036

NOTE 1

Mains Failure

This warning/alarm is only active if the

supply voltage to the frequency converter

is lost and parameter 14-10 Mains Failure

is not set to option [0] No Function

Check the fuses to the frequency converter, mains

supply to the unit and the phase imbalance (±3%)

039

Alarm

Heat Sink Sensor No feedback from the heat sink

temperature sensor

The signal from the IGBT thermal sensor is not

available on the power card. The problem could

be on the power card, on the gatedrive card, or the

ribbon cable between the power card and gate

drive card

045

Alarm

Ground Fault

Ground fault detected on motor start

• Remove power to the frequency converter and

repair the ground fault.

• Check for ground faults in the motor by mea

suring the resistance to ground of the motor

cables and the motor with a megohmmeter.

NOTE 1

Speed Limit

When the speed is outside of the specified

range in parameter 4-12 Motor Speed Low

Limit [Hz] and parameter 4-14 Motor Speed

High Limit [Hz], the frequency converter

shows a warning. When the speed is below

the specified limit in parameter 1-87 Trip

Speed Low [Hz](except when starting or

stopping), the frequency converter trips

The current is higher than the value in

parameter 4-18 Current Limit.

Ensure that motor data in parameters 1–20 to 1–
