GB - 65Error Diagnosis5. Error DiagnosisAt KEB COMBIVERT error messages are always represented with an "E." and the appropriate error code in thedisplay. Error messages cause the immediate deactivation of the modulation. Restart possible only after reset orautoreset.Malfunctions are represented with an "A." and the appropriate message. Reactions to malfunctions can vary.Operating messages during the start-up phase start with an "S".In the following the display indications and their cause are described.Display COMBIVIS Va-lue MeaningStatus MessagesbbL base block 76 Power modules for motor de-excitation lockedbon close brake 85 Brake control, brake engagedboFF open brake 86 Brake control, brake releasedCdd Calculate drive 82 Measurement of the motor stator resistance.dcb DC brake 75 Motor is decelerated by a DC voltage at the output.dLS Low speed / DC brake 77 Modulation is switched off after DC-braking .FAcc Forward acceleration 64 Acceleration with the adjusted ramps in clockwise direction of rotation.Fcon Forward constant 66 Acceleration / deceleration phase is completed and it is driven with con-stant speed / frequency in clockwise direction of rotation.FdEc Forward deceleration 65 It is stopped with the adjusted ramp times in clockwise direction of ro-tation.HCL Hardware current limit 80 The message is output if the output current reaches the hardware cur-rent limit.LAS LA stop 72 This message is displayed if during acceleration the load is limited to theadjusted load level.LdS Ld stop 73 This message is displayed if during deceleration the load is limited to theadjusted load level or the DC-link current to the adjusted voltage level.LS Low speed 70 No direction of rotation pre-set, modulation is off.nO_PU Power unit not ready 13 This message is displayed if during deceleration the load is limited to theadjusted load level or the DC-link current to the adjusted voltage level.noP No operation 0 Control release (terminal ST) is not switched.PA Positioning active 122 This message is displayed during a positioning process.PLS Low speed / power off 84 No modulation after Power-Off.PnA Position not reachable 123 The specified position cannot be reached within the pre-set ramps. Theabort of the positioning can be programmed.POFF Power off function 78 Depending on the programming of the function the inverter restarts au-tomatically upon system recovery or after a reset.POSI Positioning 83 Positioning function active (F5-G).rAcc Reverse acceleration 67 Acceleration with the adjusted ramp times in anti-clockwise direction ofrotation.rcon Reverse constant 69 Acceleration / deceleration phase is completed and it is driven with con-stant speed / frequency in clockwise direction of rotation.rdEc Reverse deceleration 68 It is stopped with the adjusted ramp times in anti-clockwise direction ofrotation.rFP Ready for positioning 121 The drive signals that it is ready to start the positioning process.SLL Stall 71 This message is displayed if during constant operation the load is limitedto the adjusted current limit.SrA Search for ref. active 81 Search for reference point approach active.SSF Speed search 74 Speed search function active, that means that the inverter attempts tosynchronize onto a running down motor.continued on next page
