Melsec iq-r simple motion module.

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
• 22100 + (400  (Ax - 1)) + (200  M) + (10  (Q - 1)) + R
