A.3.2 Exchanging components
Nominal/actual comparison of the hardware configuration
With each new calculation of the controller, a nominal/actual
comparison between the current hardware configuration
(actual configuration) and the setpoint configuration is per
formed.
Setpoint configuration The setpoint configuration consists of the values for the
drive configuration parametrised by the user.
Actual configuration The actual configuration consists of values for
the hardware
components ascertained during the automatic hardware
recognition.
Exchange of a component
The CMAX identifies an exchange as specified in Tab.A/4.

DGCI: Recognition based on serial
number of the measuring system
DGCI: Recognition based on length and
diameter information in the measuring
system
Other drives: recognition not possible Other drives: recognition not possible
