Externally Created Cam Data
A cam table can start as an excel workbook, or within Yaskawa’s Cam Tool
Software, or other cam generation software. It must be converted to a
CSV file for transfer into the MPiec motion engine memory. The CSV may
contain integer or floating point data in the same position units as defined
for each of the axes in the application via the configuration software.
Tips when using Cam Tool:
1) On the Set Style screen, select “No Unit” for the Phase & Position
(Master & Slave.) This makes it possible enter data in the same units as
already specified with the Configuration software. None of the Cam Tool
data will be converted to other units as suggested in the lower portion of
the Set Style screen, so no other information on the Set Style screen
must be entered, unless you want Cam Tool to show motor performance
characteristics at various points in the curve.
2) Save the data as a CDT or CDD file, which will preserve the original
cam data, such as curve type, for future edits. Once the file is saved in a
native Cam Tool format, then also save the file as a CSV.
NOTE: CSV files must not be Unicode format. If using excel or other
software, check for this setting. Excel has a few CSV settings, select MS-
DOS CSV output.verification.
