Overall Structure
Section 4-1
The data handled by the PCU can be classified into the following six types.
Using these data/parameter settings, the PCU executes operation (1) using
the operation settings specified in the common parameters, axis parameters,
and Servo parameters (2) based on operating commands received from the
Axis Operating Memory Areas.
The common parameters, axis parameters, and certain Servo parameters are
the basic settings for the PCU and the axes to be controlled. Therefore, these
settings must be set when using the PCU. Make the settings for other data/
parameters according to the kind of operation required.

Common
Parameter Area
This area contains the parameters
for basic setting of PCU operation,
such as allocation of the Axis
Operating Memory Areas and
MECHATROLINK communica-
tions.
The common parameters must be
set to use the PCU.
PCU's internal memory
(The parameter settings
can be saved in the
PCU's flash memory.)
The settings saved in the PCU are
enabled when read to the PCU internal
memory at power ON or restart.
Axis Parameter
Areas
These areas contain the parame-
ters for axis control settings, such
as the origin input signal selection
and origin search method.
PCU's internal memory
(The parameter settings
can be saved in the
PCU's flash memory.)
The settings saved in the PCU are read
to the PCU internal memory at power
ON or restart.
When the settings are written, they are
refreshed immediately and are enabled
after they have been written.
Servo Parame-
ter Area
These parameters are for setting
Servo Drive operation.
Servo Drive's internal
memory
(The parameter settings
can be saved in the
Servo Drive's internal
non-volatile memory.)
Online Servo Parameters are enabled
as soon as they are written, and offline
Servo parameters are enabled after the
Servo Drive power is turned OFF and
ON again, or after executing DEVICE
SETUP.
Common Oper-
ating Memory
Area
This area is for settings for com-
mon PCU operations, such as
communications control and trans-
ferring common parameters. The
status of these operations is also
input to this area.
CPU Unit's CPU Bus Unit
Area
Data is updated with every I/O refresh
of the CPU Unit.
The set data is enabled and used with
the startup of each operation.
Axis Operating
Output Memory
Areas
These areas are for settings and
operations of axis operation, such
as positioning/speed commands
and operating commands for direct
operation, origin search, and jog-
ging.
CPU Unit's memory area
set in the common
parameters.
Data is updated with every I/O refresh
of the CPU Unit.
The set data is enabled and used with
the startup of each operation.
Axis Operating
Input Memory
Areas
These areas are used to input sta-
tus information for axis opera-
tions, such as present position and
axis operation status.
CPU Unit's memory area
set in the common
parameters.
Data is updated with every I/O refresh
of the CPU Unit.
