Curves - LinMot B1100 series Manual

LinMot Drive Configuration over Fieldbus

5 Curves

NTI AG Parameterization of LinMot servo drives over fieldbus interfaces / 30.06.2016
NOTE: This chapter is only valid for E1100 drives. B1100 drives
do NOT support curve downloading over the fieldbus.
The E1100 drives can store up to 100 curves, which can be
generated and downloaded by the LinMot-Talk software. The curves
are identified by their ID (1..100).
Figure 8: Curves within LinMot-Talk
The curves, which can be accessed by the motion control firmware
through corresponding motion commands, are located in the RAM
memory space of the drive. They can be permanently stored into a
flash memory block as well. At boot time the operating system copies
the curve data from the flash memory to the RAM memory block.
The curve profiles, which are generated and downloaded using the
LinMot-Talk software, are always stored to RAM and flash memory
(permanently saved).
It is also possible to download curves to the drive over the fieldbus.
Then it is necessary to have the curve objects stored in the superior
machine controller. There are three ways to bring the profiles there:
1. The curves are created and downloaded to a drive with LinMot-
Talk. Then the curve objects can be uploaded from the drive over the
fieldbus interface (using the curve service).
2. The curves are created and then exported to a raw data file (PVL
file) using the LinMot-Talk software. Then the PVL file can be loaded
to the main controller.
3. The curve object is fully generated by the main machine controller
without using the LinMot-Talk curve tool.
