The PCU uses the data and memory areas shown in the following table.
Name
Contents
Reference
Parameter
areas
Allocated to the PC’s DM Area when the PCU’s unit
number is set. The parameters for controlling the PCU
are set in the common parameter area, and the
parameters for controlling individual axes are set in the
axis parameters area.
Note
The settings in the axis parameters area must be
made when the PCU is used. If these settings are
not made, a common parameters error will be gen-
erated (error codes 0010 to 0013) and the PCU will
not operate normally. Be sure to read

Parameters
Operating
memory
area
Allocated to the Programmable Controller’s IR Area
when the PCU’s unit number is set. This area is used
for outputting data such as operational commands to
the PCU and for inputting the PCU status.
4-4
Operating
Memory
Area
Operating
data area
This area is set by the common parameters area. It is
used for inputting information related to the transfer of
memory operation data, direct operation settings such
as positions and speeds, and status data from the
PCU.
4-5
Operating
Data Area
Data
transfer
area
This area is set by the operating data area. When data
is transferred between the Programmable Controller
and the PCU, only that portion of the area employed
for transferring the data is used.

4-1-1 Flash Memory
The contents of the PCU’s internal memory are lost when the power supply is
turned off or when the PCU is restarted. By saving the contents of the internal
memory to the flash memory, parameters and other data can be retained.
•
Axis parameters
•
Positioning sequences
•
Speeds
•
Acceleration and deceleration times
•
Dwell times
•
Zones
Note
The data for the number of axes for the particular Position Control Unit being
used is all saved at once.
For details regarding saving data, refer to
5-7 Saving Data
.
Parameters and other data that have been saved to flash memory are read to the
PCU’s internal memory when the PCU is powered up or restarted. If the parame-
ters or other data are corrupted at that time, a parameter destruction error (error
code 0001) or data destruction error (error code 0002) will be generated and the
PCU will be started up using the initial values (i.e., the factory settings) or the
parameters and data that had been saved prior to the last save to flash memory.
If parameters or data are lost, no operation other than data transfer or data
saved can be received. After transferring the data, save the data and turn the
power off and then on again, or restart the PCU.
