Programming via parameters

Parameters can be set via
• the control panel, as described in chapter
• the DriveStudio PC tool, as described in DriveStudio User Manual
(3AFE68749026 [English]), or
• the fieldbus interface, as described in chapters
fieldbus interface
All parameter settings are stored automatically to the permanent memory of the drive.
However, if an external +24 V DC power supply is used for the drive control unit, it is
highly recommended to force a save by using parameter
powering down the control unit after any parameter changes.
If necessary, the default parameter values can be restored by parameter
Param restore.
Note: By default, a selective list of parameters is shown by the drive panel or
DriveStudio. All parameters can be displayed by setting parameter
sel to Load long.

Application programming

The functions of the firmware program can be extended with application
programming. (A standard drive delivery does not include an application program.)
Application programs can be built out of function blocks based on the IEC-61131
standard. Some drive parameters are used as firmware function block inputs and can
therefore be modified also via the application program. Note that parameter changes
made via the application program override changes made via the DriveStudio PC
tool.
For more information, see
• Application guide: Application programming for ACS850 drives
(3AUA0000078664 [English]), and
• DriveSPC User manual (3AFE68836590 [English]).
Application program licensing and protection
The drive can be assigned an application licence consisting of an ID and password
using the DriveSPC tool. Likewise, the application program created in DriveSPC can
be protected by an ID and password.
If a protected application program is downloaded to a licensed drive, the IDs and
passwords of the application and drive must match. A protected application cannot be
downloaded to an unlicensed drive. On the other hand, an unprotected application
can be downloaded to a licensed drive.
and Control through a fieldbus
