Configuration using FCT
As a specification, the software end positions in FCT are
deactivated.
The specification of PNU 501:01 = PNU 501:02 = 0 will
deactivate the software end positions. However, the CMAX
limits setpoint specifications to the maximum or minimum
permissible end positions.
With the DGCI, the axis zero point cannot be edited.
Numerical example
Layout PNU Description Value
PNU 1101 1130 Offset axis zero point 25.5 mm
Cylinder
Measuring system
1111 Length of the measuring
system 280 mm
Measuring system
PNU PNU 30
1101 Length of drive 350 mm
PNU 1111 PNU 1130
The CMAX calculates the following limit values for the two
end positions:
PNU Description Minimum Maximum
501:01 Lower hardware end position,
minimum lower software end
position 25.5 mm < upper software end posiĆ
tion
501:02 Upper hardware end position,
maximum upper software end
position > lower software end posiĆ
tion 280 − 25.5 = 254.5 mm
