Memory Operation Data
The memory operation data is used for setting the data for memory operation
commands output to the PCU. The memory operation data settings must be
made in the PCU’s internal memory before commands are sent.
When a memory operation command (START, INDEPENDENT START) is sent
to the PCU from the operating memory area, the PCU executes the command
based on the memory operation data settings.
Settings for memory operation data can be saved to flash memory.
4-6-1 Outline
Memory operation data consists of the following six types of data. Settings for
this data can be written from the CPU Unit to the PCU using data transfer.
1, 2, 3...
1. Positioning sequences
2. Speeds
3. Positions
4. Acceleration times
5. Deceleration times
6. Dwell times
For details of memory operation and the correlation between the different types
of data, refer to
Section 8 Memory Operation
.
The address allocation of the memory operation data is shown in the following
tables. The addresses shown in the table are the PCU’s internal addresses.
When writing data, specify the destination address as appropriate. For details
on performing data transfer, refer to
Section 5 Transferring and Saving Data
.
