Commissioning function data reset
PNU PNU: 1192 Index: 3 Max index: 8 Class: Struct Data type: int32
Values Without unit
Default: 0 Minimum: 0 Maximum: 3
This parameter serves to delete axis and identification data.
The axis data must be deleted if a new drive was connected to the CMAX or if the system of measure
ment is to be changed.
Deleting identification data can make sense if modifications were made in the system that lead to a
significantly different positioning behaviour. They need to be deleted if one of the following para
meters is to be deleted:
Cylinder type or cylinder length by more than 5.00 mm
Cylinder diameter or piston rod diameter
Dual axis" setting
Measuring system type or measuring system length of more than 5.00 mm
Valve type
Supply pressure with a change of more than 1 bar
Mounting position with a change of more than 3°
The parameter can only be written (reading always delivers 0):
= 0: No effect
= 1: reserved
= 2: Delete identification data
= 3: Delete axis data and identification data
When deleting the axis data, the CMAX carries out the following steps:
1. Deactivate controller.
2. Reset axis data to delivery status, delete identification data and adaptation data.
3. Transition to status C00: Waiting for system of measurement
The diagnostic memory is not deleted during axis data reset.
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.
