Cylinder length
PNU PNU: 1101 Index: 1 Max index: 1 Class: Var Data type: int32
Values Unit: Length (index = 2)
Linear drive Semi−rotary drive
Dimension Default Minimum Maximum Dimension Default Minimum Maximum
SI 0.01 mm 0 5.000 1.000.000 0,1 ° 0 500 100.000
Imperial 0.01 mm 0 5.000 1.000.000 0,1 ° 0 500 100.000
The cylinder length is stored in the sensor interface. Standard cylinders are not longer than
2,000 mm, the value range includes reserves for special applications.
When exchanging the drive, no projecting needs to be carried out as long as the specified cylinder
length deviates from the recognized cylinder length by no more than 5.00 mm. This also allows op
timization of the effective stroke.
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.
Cylinder diameter
PNU PNU: 1102 Index: 1 Max index: 1 Class: Var Data type: int32
Values Unit: Diameter (index = 11)
Linear drive Semi−rotary drive
Dimension Default Minimum Maximum Dimension Default Minimum Maximum
SI 0.01 mm 0 1.200 20.000 0.01 mm 0 1.200 20.000
Imperial 0.01 mm 0 1.200 20.000 0.01 mm 0 1.200 20.000
The cylinder diameter is stored in the sensor interface.
If the cylinder diameter was recognized by CMAX (e.g. during DGCI), the value cannot be overwritten.
Parallel axes can be parametrised in the FCT by specifying double axis", the CMAX then automatically
calculates the resulting piston surface.
Other diameters can only be projected via user−specific cylinder types.
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.
