Handling, Diagnostic and Service Functions
Brief Description
The controller firmware via data maps the drive to an internal
mathematical model. All operating data relevant therefor are mapped to
parameters. An identification number (IDN) is assigned to each
parameter. The IDN allows accessing operating data via
• the serial interface
- or -
• a master communication interface suited for data transfer.
The operating data stored in parameters can be identified by means of
the IDN. They can be read and transferred, if required. The user write
access to parameters depends on the properties of the respective
parameter and the current communication phase. Specific parameter
values (operating data) are checked for validity by the drive firmware.
Functional Description
Each parameter consists of seven data block elements.
Element No. Designation
1 identification number
(IDN)
2 name
3 attribute
4 unit
5 minimum input value
6 maximum input value
7 operating data
