The following chapter shall help you to avoid errors as well as help you to determine
and remove the cause of errors on your own.
If error messages or malfunctions occur repeatedly during operation, the first thing to
do is to pinpoint the exact error. To do that go through the following checklist:
- Is the error reproducable ?
For that reset the error and try to repeat it under the same conditions. If the error can
be reproduced, the next step is to find out during which operating phase the error
occurs.
- Does the error occur during a certain operating phase (e.g. always during
acceleration)?
If so, consult the error messages and remove the causes listed there.
- Does the error occur or disappear after a certain time?
That may be an indication for thermal causes. Check, whether the inverter is used in
accordance to the ambient conditions and that no moisture condensation takes place.
At KEB COMBIVERT error messages are always represented with an „E." and the
appropriate error in the display. Error messages cause the immediate deactivation of
the modulation. Restart possible only after reset.
Malfunction are represented with an „A." and the appropriate message. Reactions to
malfunctions can vary.
Status messages have no addition. The status message shows the current operating
status of the inverter (e.g. forward constant run, standstill etc.).
In the following the display and their cause are described.
Value Meaning
76 Power modules for motor de-excitation locked
85 Brake control, brake engaged (see chapter 6.9)
86 Brake control, brake released (see chapter 6.9)
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 (see chapter 6.9
„DC-Braking").
64 Acceleration with the adjusted ramps in clockwise direction
of rotation.
66 Acceleration / deceleration phase is completed and it is
driven with constant speed / frequency in clockwise direction
of rotation.
65 It is stopped with the adjusted ramp times in clockwise
direction of rotation.
80 The message is output if the output current reaches the
hardware current limit.
