Ex.
When the buffer memory address that satisfies the following conditions is determined
• Axis 3
• Start block No.2
• Block start data point: 40
22000 + (400  (3 - 1)) + (200  2) + (40 - 1) = 23239
■[Da.13] Special start instruction, [Da.14] Parameter
Use the following calculation formula.
• 22050 + (400  (Ax - 1)) + (200  M) + (P - 1)
For each variable, substitute a number following the description below.

Ex.
When the buffer memory address that satisfies the following conditions is determined
• Axis 2
• Start block No.1
• Block start data point: 25
22050 + (400  (2 - 1)) + (200  1) + (25 - 1) = 22674
Condition data
Condition data consists of five start blocks from Start block 0 to 4, and the condition data No.1 to 10 are assigned to each
block. The start blocks are assigned to each axis. Condition data has the following structure.

When setting block start data using a program, determine buffer memory addresses using the following calculation formula
and set the addresses.
• 22100 + (400  (Ax - 1)) + (200  M) + (10  (Q - 1)) + R

Up to 10 condition data points can be set
(stored) for each block No. in the buffer memory
addresses shown on the left.
Items in a single unit of condition 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.
