Block Start Data
Before explaining the block start data setting items [Da.11] to [Da.14], the configuration of the block start data is shown below.
The block start data stored in the buffer memory of the Simple Motion module is the following configuration.
The following explains the block start data setting items [Da.11] to [Da.14]. (The buffer memory addresses shown are those of
the "1st point block start data (block No.7000)".)
• To perform a high-level positioning control using block start data, set a number between 7000 and 7004 to
the "[Cd.3] Positioning start No." and use the "[Cd.4] Positioning starting point No." to specify a point
number 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 Simple Motion module, up to 50 "block start data" points and up to 10 "condition data" items can be
assigned to each "block No.".
*1 Setting cannot be made when the "Pre-reading start function" is used. If you set any of Nos. 7000 to 7004 and perform the Pre-reading
start function, the error "Outside start No. range" (error code: 19A3H)" will occur.
Refer to the following for details.

Up to 50 block start data points can be
set (stored) for each axis in the buffer
memory addresses shown on the left.
Items in a single unit of block start data
are shown included in a bold frame.
Each axis has five start blocks (block
Nos. 0 to 4).
Start block 2 to 4 are not allocated to
buffer memory.
Set with the engineering tool.
