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 recognised cylinder length by no more than 5.00 mm. This also allows
optimisation of the effective stroke.

ý

The parameter value cannot be changed.

o

Writing permissible only in commissioning/parametrising mode with disabled controller.

o

This parameter can be written by FCT without higher−order controller.

o

After writing, controller recalculation is carried out.

Parameter values:

ć For integer parameters (int32) with a physical unit, the unit and the values

(default, minimum, maximum) are specified for each system of measurement
(example).

ć For integer parameters (int32) without a physical unit, only default, minimum and

maximum values are specified.

ć With bitfields (bitarray), the default value is specified. It is also specified which

bit can assume which value 0, 1 or x (any) during writing. With bitfields the CMAX
checks the status of the individual bits, not a value range.

ć Strings (char) are specified with their default values and the permissible characĆ

ters during writing.
