By selecting a profile type, the commissioning of field bus drives becomes
very easy for the user. The advantage of the profile selection is that all
important basic settings for the desired drive function are thereby made
automatically in the drive. As the profile types are defined independent of
the bus, the transfer of applications from one field bus to the other is also
facilitated.
A status (e.g. Drive Halt, drive error, ...) represents a specific internal and
external behavior. The status can be exited by defined events (e.g. drive
commands, switching of operating modes, ...). Corresponding status
transitions are assigned to the events. The interaction of control and
status bits or the status transitions are called status machine.

Assignment to the Drive-Internal Operating Modes
Note:
By selecting the I/O mode (P-0-4084 = 0xFF82) the primary
mode of operation active in the drive is defined. "Jogging" or
"drive-controlled positioning - jog mode" is automatically set as
the 1
st
secondary operating mode.
There are the following relationships between the parameters
P-0-4084,
Profile type
and
S-0-0032,
Primary mode of operation
:
•
I/O mode
with 16-bit status word and 16-bit control word
(P-0-4084 = 0xFF82
→
functionally compatible with DKC3.1)
This means that the drive is operated in the mode "positioning block
mode, encoder 1, lagless"!
•
Freely configurable mode
•
no profile-dependent settings and checks
•
free configuration of real-time channel by configuration lists
P-0-4080 and P-0-4081
•
allows analog operation for initial commissioning
