(7) If the master axis is a main CPU control axis controlled to short cut to rotation move axis, set the main
axis stroke type of the synchronous electronic CAM movement settings to stroke length. If you specify
stroke end position, intended synchronous movement may not be performed.
[Example] In case of synchronous movement from master axis position 10q to 350q
If you set the master axis stroke type as stroke end position and stroke end position to be 350q,
the movement is performed as shown in the figure below.
