Program features 27
Adaptive programming
Conventionally, the user can control the operation of the drive by parameters.
However, the standard parameters have a fixed set of choices or a setting range. To
further customize the operation of the drive, an adaptive program can be constructed
out of a set of function blocks.
The Drive composer PC tool has an Adaptive programming feature with a graphical
user interface for building the custom program. The function blocks include the usual
arithmetic and logical functions, as well as eg. selection, comparison and timer
blocks. The program can contain a maximum of 20 blocks. The adaptive program is
executed on a 10 ms time level.
For selecting input to the program, the user interface has pre-selections for the
physical inputs, common actual values, and other status information of the drive.
Parameter values as well as constants can also be defined as inputs. The output of
the program can be used eg. as a start signal, external event or reference, or
connected to the drive outputs. Note that connecting the output of the adaptive
program to a selection parameter will write-protect the parameter.
The status of the adaptive program is shown by parameter 07.30 Adaptive program
status. The adaptive program can be disabled by 96.70 Disable adaptive program.
Please note that sequential programming is not supported.
For more information, see the Adaptive programming application guide
(3AXD50000028574 [English]).
Application programming
The functions of the firmware program can be extended with application
programming. Application programmability is available as option +N8010.
Application programs can be built out of function blocks based on the IEC 61131-3
standard using a PC tool available separately.
For more information, see Programming manual: Drive application programming
(IEC 61131-3) (3AUA0000127808 [English]).
