Fault Codes - Siemens COMBIMASTER Reference Manual

COMBIMASTER & MICROMASTER Integrated
REFERENCE MANUAL

6.2 Fault Codes

Fault codes are only available when an OPm2 is connected to the COMBIMASTER.
In the event of a failure, the COMBIMASTER 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 Cause
Code
F001 Overvoltage
F002 Overcurrent
F003
Overload
F004
Overheating of motor
(monitoring with PTC)
F005 Inverter overtemperature
(Heatsink PTC)
F008
USS protocol timeout
F009
Undervoltage
F010
Initialisation fault / Parameter loss *
F011 Internal interface fault *
F012 External trip
F013
Programme fault *
F030 PROFIBUS link failure
F031 Option module link failure
F033 PROFIBUS configuration error
F036
PROFIBUS module watchdog trip
F074
Motor overtemperature by I
calculation
F105 COMBIMASTER internal
overtemperature (electronics PTC)
F106
Parameter fault P006
F112 Parameter fault P012/P013
F212 Parameter fault P211/P212
* Ensure that the wiring guidelines described in Electrical Installation have been complied with.
When the fault has been corrected, restart the inverter and the motor will run if the fault has been cleared.

Corrective Action
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.
Check motor lead and motor for short-circuits and earth
faults.
Increase the ramp-up time (P002).
Increase the ramp down time (P003)
Reduce the boost set in P078 and P079.
Check whether the motor is obstructed or overloaded.
Check whether the motor is overloaded.
Check if motor is overloaded.
Check the connections to the PTC.
Has P087 been set to 1 without a PTC being
connected?
Check that the ambient temperature is not too high.
The motor speed may be too low for a given load.
Check the serial interface.
Check the settings of the bus master and P091 - P093.
Check whether the timeout interval is too short (P093).
Check that the power supply is supplying enough
voltage to the inverter.
Check the entire parameter set. Set P009 to `0000'
before power down.
Switch off power and switch on again.
Source of trip is digital input (configured as an external
trip input) going low - check the external source.
Switch off power and switch on again.
Check the integrity of the link.
Check the integrity of the link.
Check the PROFIBUS configuration.
Replace PROFIBUS module
2
t Check that the motor current does not exceed the value
set in P083.
Check that the ambient temperature is not too high.
The motor speed may be too low for a given load.
Programme one or more Digital Inputs to be fixed
frequencies.
Change P006 to 0 or 1.
Set parameter P012 < P013.
Set parameter P211 < P212.
