Lust CDA3000 - Initial Commissioning

4-6
Engineering Guide CDA3000
4 Software functions
4.1.2 Initial
commissioning
Selecting the “Initial commissioning” subject area calls up the parameter
group for initial commissioning of the inverter module. The parameters of
the subject area must be adapted successively to the specific application.
The automatic motor identification function ascertains the key parameters
of the motor and sets the appropriate control circuits.
This identification function is necessary for the SFC
1
and FOR
2
control
modes. Where the VFC
3
open-loop control mode is used it is only
required if the particularly high demands are placed on the current control
loop (e.g. very heavy load surges in operation).
Sequence of initial commissioning
