Piston rod diameter
PNU PNU: 1103 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 0 20.000 0.01 mm 0 0 20.000
Imperial 0.01 mm 0 0 20.000 0.01 mm 0 0 20.000
The piston rod diameter cannot be recognized automatically. However, the Festo standard drives
have a fixed allocation of cylinder diameters to piston rod diameters. This allocation is stored in the
FCT.
With other drives and special applications, the piston rod diameter can be parametrised as required
by using the user−defined type.
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.
Measuring system type (sensor type)
PNU PNU: 1110 Index: 1 Max index: 1 Class: Var Data type: int32
Values Without unit
Default: 0 Minimum: 1 Maximum: 4
The sensor type is read from the sensor interface.
If the sensor interface delivers no known type, a fault (E04) is generated. The sensor interface is not
commissioned in this case.
