Response of the CMAX to exchanging for the same type
ć The identification data is not discarded.
ć Operation is permissible without new parametrisation/
identification.
ć A warning is generated. It remains active as long as no
formal parametrisation/identification is performed.
Response of the CMAX to exchanging for another type or
size
ć The identification data is not discarded.
ć Operation is not permissible without new parametrisation,
the controller cannot be activated.
ć An error is generated.
Cylinder length The cylinder length and the sensor length may be modified
by up to 5.00 mm without requiring a new identification.
When modifying by < 5.00 mm, the CMAX assumes that it is
expected to optimize the effective length of the cylinder.
When commissioning the CMAX offline, the nominal length of
the cylinder must be specified. It is accepted even if it deviĆ
ates by more than 5.00 mm from the effective length.
If the cylinder was exchanged, it must in any case be re−
identified, even if the CMAX does not report an error!
Adjust setpoint parameters
The parameters of the mechanical system can only be modiĆ
fied once the identification data have been deleted.
