Transferring Positioning Sequences
When performing memory operation, it is necessary to write memory operation
data (positioning sequences, speeds, positions, acceleration times, decelera-
tion times, and dwell times) to the PCU’s internal buffer (RAM) in advance. The
data can be written to the PCU using either of the following methods.
•
First, save the memory operation data to the PCU’s flash memory using CX-
Position, and then write this data from the flash memory at startup.
•
Save the data to the DM or EM Area of the CPU Unit, and then, using the data
transfer function, transfer this data to the PCU where it is written to the buffer.
A simple example of the procedure for transferring positioning sequences to the
PCU using the second method is explained here. The same method can be used
for data other than positioning sequences. For further details on transferring
data, refer to
Section 5 Transferring and Saving Data
.
8-7-1 PCU’s Internal Addresses
•
When transferring data to the PCU, it is necessary to specify an internal PCU
address.
•
The PCU’s internal addresses are shown in the following table. For details,
refer to
