Setting area
Enable timing
Common parameter
area
(Refer to
4-2 Common
Parameter Area
.)
This area contains the parameters for
settings related to basic PCU operation,
such as allocation of the operating
memory area.
The common parameters must be set
when using the PCU.
DM Area words in the
CPU Unit allocated to
Special I/O Units
The settings are
transferred from the
CPU Unit to the PCU at
power up or restart and
enabled.
Axis parameter area
(Refer to
4-3 Axis
Parameter Area
.)
This area contains the parameters for
settings related to axis operation, such
as pulse output type, logic for input
signals, operation modes, and
maximum speed values.
DM Area words in the
CPU Unit allocated to
Special I/O Units
PCU’s flash memory
(See note on previous
page.)
These settings are
transferred from the
CPU Unit’s DM Area or
the PCU’s flash memory
to the PCU’s internal
memory at power up or
restart and enabled.
Operating memory area
(Refer to
4-4 Operating
Memory Area
.)
Outputs for controlling PCU operation,
such as for direct operation, memory
operation, jogging, and origin search,
are allocated to this area. Information
(see note) relating to the status of the
PCU, such as busy flags, error flags,
and external input are input to this area.
CPU Unit’s Special I/O
Unit Area
Operating commands
are sent from the CPU
Unit to the PCU and
status data is sent from
the PCU to the CPU
Unit with every I/O
refresh.
Operating data area
(Refer to
4-5 Operating
Data Area
.)
This area is for settings such as
positions, speeds, and
acceleration/deceleration times for
direct operation, origin searches and
jogging, as well as positioning sequence
numbers for memory operation. It also
contains PCU status data (see note),
such as present positions and the
number of the currently executed
positioning sequence.
CPU Unit’s DM or EM
area (determined by
common parameter
setting)
Data is updated with
every I/O refresh. The
set data is enabled and
used with the startup of
each operation.
Memory operation data
(Refer to
4-6 Memory
Operation Data
.)
This area is for settings related to
memory operation, such as operation
sequences, positions, speeds, and
acceleration/deceleration times. The
memory operation area contains the
following six types of data:
•
Positioning sequences
•
Speeds
•
Positions
•
Acceleration times
•
Deceleration times
•
Dwell times
PCU’s internal memory
(can be saved to PCU’s
flash memory)
Data is read from the
PCU’s flash memory to
the internal memory at
power up or restart.
Settings are updated
when data is
transferred. The set
data is enabled and
used with the startup of
each memory operation.
Zone data
(Refer to
4-7 Zone Data
Area
.)
This data determines zones for the
present positions of axes controlled by
the PCU.
PCU’s internal memory
(can be saved to PCU’s
flash memory)
Data is read from the
PCU’s flash memory to
the internal memory at
power up or restart.
Settings are updated
when data is
transferred.
Note
Error codes are input to the operating memory area.
Using these settings, the PCU executes operation (1) using the data/parameter
areas specified in the common parameters and axis parameters (2) according to
the operating commands received from the operating memory area and (3)
based on operating data, memory operation data, and zone data.
The common parameters and axis parameters are basic settings for the PCU
and the axes to be controlled. It is necessary to make these settings when using
the PCU. Make settings for operating data, memory operation data, and zone
data according to the kind of operation required.
