Fuel/air ratio internal checking error: cyclical data
check
1
Check synchronisation data, different current load
2
Check synchronisation data, different target load
4
Check synchronisation data, different target positions
16
Check synchronisation data, different positions reached
May be caused by different standardisation speeds (for example
following the resetting of the data set) when the VSD is active ->
perform the standardisation again and check the regulation of
the fuel/air ratio.

VSD control range limit
The standard unit could not correct the speed difference and
has reached a limit in the control range.
1. The base unit is not standardised for this motor
----> repeat the standardisation.
WARNING!
check the settings of the air/fuel ratio control!
2. The VSD train times are not shorter than those of the
standard unit (parameters 522, 523).
3. The VSD characteristic is not linear. The VSD voltage input
configuration must correspond with that of the standard unit
(parameter 645).
4. The VSD does not follow the changes of the standard unit
quickly enough. Check the VSD settings (input filter, slide
compensation, different latent speeds).
1
Lower control range limit
The VSD speed was too high.
2
Upper control range limit
The VSD speed was too low.
81
1
Interruption in speed limit input
Excessive electromagnetic interference on the sensor line ->
improve the EMC.

Error during VSD speed standardisation
1
Standardisation time-out (the descent time of the VSD train
is too long)
Time-out at the end of the standardisation, during deceleration
of VSD.
1. The VSD train times are not shorter than those of the
standard unit (parameter: 523).
2
Logging of the standardised speed not successful
Error during the logging of the standardised speed ---> block the
standard unit, reset it and repeat the standardisation.
