• To perform a high-level positioning control using block start data, set a number between 7000 and 7004 to
"[Cd.3] Positioning start No." and use "[Cd.4] Positioning starting point No." to specify a point No. between 1
and 50, a position counted from the beginning of the block.
• The number between 7000 and 7004 specified here is called the "block No.".
• With the Motion module, up to 50 "block start data" points and up to 10 "condition data" items can be
assigned to each "block No.".
