Transferring and Saving Data
With memory operation, the Position Control Unit (PCU) is operated by specify-
ing positioning sequences that have been set for the PCU. (Refer to
4-6 Posi-
tioning Sequence Details
.) Data must be transferred because various kinds of
data, including positioning sequences, are created by the user according to the
purpose of the operation and then saved to the PCU.
To modify part of the data, transfer it first by specifying its address.
Data can be transferred in the following ways:
1, 2, 3...
1. Using a Data Transfer Bit. Refer to
5-2 Writing Data with the Data Transfer
Bit
and
5-3 Reading Data with the Data Transfer Bit
.
2. Using the IOWR and IORD instructions. Refer to
5-4 Writing Data with
IOWR
and
5-5 Reading Data with IORD
.
3. Using the NC Support Tool. Refer to
5-6 Creating and Transferring Data with
SYSMAC-NCT Support Tool
.
Note
1. Do not attempt other data transfers or storage operations while a data trans-
fer is already in progress, or it will result in a multiple start error (error code
8000).
2. Carefully check to be sure that the parameters and data have been properly
set for correct operation.
The transferred data is written to the Position Control Unit’s memory, but it will be
lost if the power is turned off or if the Unit is restarted. To keep the transferred
data permanently in the Position Control Unit, it will need to be saved there.
(Refer to
5-7-2 Procedure for Saving Data
.) Once saved, the data is kept in the
flash memory of the Position Control Unit, and can be used the next time the
power is turned on or the Unit is restarted. If the data is merely transferred with-
out being saved, when the power is cut off the contents of the memory will revert
to whatever was saved previously.
The saved data is automatically transferred from the flash memory to the Unit’s
internal memory as soon as the Unit’s power is turned on or as soon as the Unit is
restarted.
By means of the common parameter settings, either the flash memory or the DM
can be selected for the reading of axis parameters.
Note
1. Do not turn off the power or restart the Unit while the data is being saved. It
can cause a fault in the Unit’s internal flash memory. Saving data may take
up to 30 seconds.
2. Data cannot be saved while a data transfer is in progress or while the Unit is
busy. Any attempt to execute a save will result in a multiple start error (error
code 8000).
