5. FAULT CODES

Fault codes are only available when an OPm2 is connected to the CombiDrive

In the event of a failure, the CombiDrive

switches off and a fault code appears on the LCD screen. The last

fault that occurred is stored in parameter P930. e.g. ‘0003' indicates that the last error was F003.

Fault Code Cause Corrective Action

F001

Overvoltage Check whether supply voltage is within the limits indicated on the rating plate.

Increase the ramp down time (P003).

Check whether the required braking power is within the specified limits.

F002

Overcurrent Check motor lead and motor for short-circuits and earth faults.

Increase the ramp-up time (P002).

Reduce the boost set in P078 and P079.

Check whether the motor is obstructed or overloaded.

F003

Overload Check whether the motor is overloaded.

F004

Overheating of motor

(monitoring with PTC)

Check if motor is overloaded.

Check the connections to the PTC.

Has P087 been set to 1 without a PTC being connected?

F005

Inverter overtemperature

(internal PTC)

Check that the ambient temperature is not too high.

The motor speed may be too low for a given load.

F006

Power module overtemperature Check that the ambient temperature is not too high.

F008

USS protocol timeout Check the serial interface.

Check the settings of the bus master and P091 - P093.

Check whether the timeout interval is too short (P093).

F009

Undervoltage Check that the power supply is supplying enough voltage to the inverter.

F010

Initialisation fault / Parameter loss * Check the entire parameter set. Set P009 to `0000' before power down.

F011

Internal interface fault * Switch off power and switch on again.

F012

External trip Source of trip is digital input (configured as an external trip input) going low -

check the external source.

F013

Programme fault * Switch off power and switch on again.

F018

Auto restart after fault Automatic restart after fault (P018) is pending.

WARNING: The motor shaft may start to rotate at any time.

F030

PROFIBUS link failure Check the integrity of the link.

F031

Option module link failure Check the integrity of the link.

F033

PROFIBUS configuration error Check the PROFIBUS configuration.

F036

PROFIBUS module watchdog trip Replace PROFIBUS module

F074

Motor overtemperature by I

calculation

Check that the motor current does not exceed the value set in P083.

F106

Parameter fault P006 Parameterise fixed frequency(ies) and/or motor potentiometer on the digital

inputs.

F112

Parameter fault P012/P013 Set parameter P012 < P013.

F151 - F153

Digital input parameter fault Check the settings of digital inputs P051 to P053.

F201

P006 = 1 while P201 = 2 Change parameter P006 and/or P201.

F212

Parameter fault P211/P212 Set parameter P211 < P212.

* Ensure that the wiring guidelines described in section 2.1 have been complied with.

When the fault has been corrected, restart the inverter and the motor will run if the fault has been cleared.
