Note
During memory operation, PCU status is input for the axis that started opera-
tion or the actual moving axis/axes specified by the axis designation. For
details on which axis/axes status is input, refer to 8-1-2 Axis Designation and
Flags .
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 com-
mand based on the memory operation data settings.
Settings for memory operation data can be saved to flash memory.
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. 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.

Operation
Indicates the present position
of the axes controlled by the
PCU. The position is indi-
cated for the range
–2,147,483,647 to
2,147,483,647 pulses as
signed 32-bit hexadecimal
data using two words.
Indicated range: 80000001 to
7FFFFFFF Hex
(–2,147,483,647 to
2,147,483,647)
In memory operation, indi-
cates the number of the
sequence currently being
executed.
Indicates the output code
when in memory operation.
