Offset axis zero point
PNU PNU: 1130
Values Unit: Position (index = 1)
Linear drive
Dimension
SI 0.01 mm
Imperial 0.001 in
Difference between the axis zero point (AZ) and the reference position (REF) or difference between
the axis zero point (AZ) and the sensor zero point (SZ).
The axis zero point (AZ) is calculated as:
AZ = REF + offset axis zero point (DNCI)
or AZ = SZ + offset axis zero point (external measuring system: potentiometer)
The axis zero point must be placed on the cylinder zero point for servo−pneumatic drives. With the
DGCI the measuring system is calibrated, specification of an offset is not permitted.
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.
