Appendix 2 How To Determine Buffer Memory Addresses - Mitsubishi Electric MELSEC iQ-R Series User Manual

Appendix 2
This section describes how to determine the buffer memory addresses of positioning data, block start data, and condition
data.
Positioning data
Positioning data has the following structure.
Positioning data No.1
Positioning identifier
[Da.1] to [Da.4]
[Da.10] M code/Condition data
No./Number of LOOP to LEND
repetitions/Number of pitches
[Da.9]
Dwell time/JUMP destination
positioning data No.
Positioning option
[Da.27] to [Da.29]
[Da.8]
Command speed
[Da.6]
Positioning address/
movement amount
[Da.7]
Arc address
Axis to be interpolated No.
[Da.20] to [Da.22]
*1 Always set "0" to the part not used.
When setting positioning data using a program, determine buffer memory addresses using the following calculation formula
and set the addresses.
*1
+ (1000  (Ax - 1)) + 10  (N - 1) + S
• 6000
*1 The value is 71000 when setting [Da.20] to [Da.22].
