Item No. 2 539 042, 3070901HO
As an aid for the use of standard PROFIBUS-DP tools, there is a so-called GSD
file (electronical data sheet) with device informations. It is available by diskette
with the item no. 1 543 062, or by download from our Internet homepage.
The GSD file "HENx00B7.GSD" contains the available encoder parameters.
1. Reading-in the GSD files
• Copy the GSD file (HENx00B7.GSD) to your ..\GSD directory
• Copy the bitmap files (RA58---N.BMP and RA58---S.BMP) to your
..\BITMAP directory
• From the File menu, select the “Scan GSD Files” item
2. Configuration of the master system
• Load an existing program file (menu File - ”Open” item) or create a new one
(choose from the File menu the ”New” item, selecting a corresponding master
from the list).
3. Configuring the encoder and setting its parameters
• Open the menue ”Slave Parameters” and define the device address.
Then choose the “ENCODER” family and select the “RA58-P” station type
Example of start-up procedure by standard PROFIBUS-DP tools with the GSD file (here by COM PROFIBUS example)
• From the “Preset Configuration” list, choose the desired configuration (see
table on page 3)
• In the “Configure” window, complete the desired entries (Remarks, I Adress,
O Address)
• Now, in the “Parameterize” window, you may modify the encoder parameters
correspondingly (see figure above): Click on the respective field from the
“Value” column and activate the “Select...” button.
Parameter indications:
Sampling rate (velocity only)
: By this bit, the internal encoder timer’s sampling
rate will be set to 1 or 10 ms. (With 10 ms, the encoder provides larger speed
and acceleration values at a low number of turns.)
Steps per turn
: The number of measuring steps per turn (resolution) may be
adjusted in a range from 1 up to the maximum possible physical resolution.
Total measuring range (units)
: Having indicated the total number of measur-
ing steps, you find the encoder standing at zero. The value’s four bytes are
divided into Low word and High word. (In the figure above, the total value of
67,108,864 [= 26 bit] results from the High word’s setting to 1,024 and the Low
word’s setting to 0).
Subject to technical modifications and improvements serving the progress of our devices.
