Disable adaptation
PNU PNU: 1175 Index: 1 Max index: 1 Class: Var Data type: int32
Values Without unit
Default: 0 Minimum: 0 Maximum: 1
This parameter is used to deactivate adaptation. This is practically not required in any configuration,
only in extremely rare cases does adaptation worsen the positioning behaviour. In most case adaptaĆ
tion is useful. It improves the absolute reachable precision of the drive.
Important:
Worsening of the positioning behaviour is not in all cases caused by a faulty adaptaĆ
tion. Wear or an invalid design can cause e. g. the positioning times to incr ease or even the number
of E30 fault messages to grow. Therefore adaptation should only be deactivated in justified cases.
Load changes are usually no reason to deactivate adaptation.
A faulty adaptation could be the reason for the following behaviour:
Ĉ After commissioning, the positioning behaviour deteriorates with time. Positioning times become
longer, the machine cycle becomes longer. Fault E30 occurs frequently.
Ĉ After identification the behaviour is significantly better without any other changes having been
made. But then is slowly starts be worsen again until you perform the next identification.
In these cases, adaptation could be the reason. If you think this is the case, you should deactivate
adaptation and then re−run the identification. If the positioning behaviour does not change afterĆ
wards, adaptation was probably the reason and it should remain deactivated.
Values:
0 = Adaptation is performed
1 = Adaptation is disabled
o The parameter value cannot be changed.
ý Writing permissible only in commissioning/parametrising mode with disabled controller.
o This parameter can be written by FCT without higher−order controller.
ý After writing, controller recalculation is carried out.
