9.2 Motor and Scale Parameter File Requirements for
SERVOPACKs for Linear Motors
If a 3rd party motor shall be operated, then a motor parameter file has to be created by Yaskawa. To cre-
ate this file, provide Yaskawa with the following information: motor data and a sample motor for check-
ing the overload characteristics. Send these information to the YASKAWA Europe Headquarter, please
find the address on the last cover page.
