Error Diagnosis - KEB Combivert F5 Instruction Manual

Error Diagnosis

5. Error Diagnosis
At KEB COMBIVERT error messages are always represented with an "E." and the appropriate error code in the
display. Error messages cause the immediate deactivation of the modulation. Restart possible only after reset or
autoreset.
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.

76 Power modules for motor de-excitation locked
85 Brake control, brake engaged
86 Brake control, brake released
82 Measurement of the motor stator resistance.
75 Motor is decelerated by a DC voltage at the output.
77 Modulation is switched off after DC-braking .
64 Acceleration with the adjusted ramps in clockwise direction of rotation.
Acceleration / deceleration phase is completed and it is driven with con-
66
stant speed / frequency in clockwise direction of rotation.
It is stopped with the adjusted ramp times in clockwise direction of ro-
65
tation.
The message is output if the output current reaches the hardware cur-
80
rent limit.
This message is displayed if during acceleration the load is limited to the
72
adjusted load level.
This message is displayed if during deceleration the load is limited to the
73
adjusted load level or the DC-link current to the adjusted voltage level.
70 No direction of rotation pre-set, modulation is off.
This message is displayed if during deceleration the load is limited to the
13
adjusted load level or the DC-link current to the adjusted voltage level.
0 Control release (terminal ST) is not switched.
122 This message is displayed during a positioning process.
84 No modulation after Power-Off.
The specified position cannot be reached within the pre-set ramps. The
123
abort of the positioning can be programmed.
Depending on the programming of the function the inverter restarts au-
78
tomatically upon system recovery or after a reset.
83 Positioning function active (F5-G).
Acceleration with the adjusted ramp times in anti-clockwise direction of
67
rotation.
Acceleration / deceleration phase is completed and it is driven with con-
69
stant speed / frequency in clockwise direction of rotation.
It is stopped with the adjusted ramp times in anti-clockwise direction of
68
rotation.
121 The drive signals that it is ready to start the positioning process.
This message is displayed if during constant operation the load is limited
71
to the adjusted current limit.
81 Search for reference point approach active.
Speed search function active, that means that the inverter attempts to
74
synchronize onto a running down motor.
