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 2 t
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.
