Profibus-DP Configuration
„ To simplify the drive configuration, the GSD file can be obtained at
www.yaskawa.com . Select Downloads, By Inverter Drives, By
Product, and Network Comms-Profibus. Then select the file named
YASK00CA.GSD.
„ Load the GSD file, YASK00CA.GSD, into the proper directory for the
configuration tool used. Retrieve the GSD file form either
www.yaskawa.com or www.profibus.org to make sure that the latest
GSD file is loaded.
„ Select the Profibus-DP INTER device when adding Yaskawa drives to
the Profibus configuration. See the figure to the right.
„ The Profibus-DP Option Card supports three configuration options:
Extended Data 1 (32 words of input and output), Extended Data 2 (12
words of input and output) and Basic Data (3 words of I/O). Refer to the
Profibus-DP Option Technical Manual (TM.AFD.12) for further
information on each configuration. See the figure to the right.
