Overall Structure
Section 4-1
The data handled by the PCU can be classified in the way shown below.
Note
Error codes are input to the operating memory area.
Using these settings, the PCU executes operation (1) using the data/parame-
ter 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.
Data name
Contents
Setting area
Enable timing
Common parameter area
(Refer to
4-3 Common
Parameter Area
.)
This area contains the parameters for
settings related to basic PCU operation,
such as allocation of the operating mem-
ory 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 trans-
ferred from the CPU Unit
to the PCU at power up
or restart and enabled.
Axis parameter area
(Refer to
4-4 Axis Param-
eter Area
.)
This area contains the parameters for
settings related to axis operation, such
as pulse output type, logic for input sig-
nals, 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 trans-
ferred from the CPU
Unit’s DM Area or the
PCU’s flash memory to
the PCU’s internal mem-
ory at power up or
restart and enabled.
Operating memory area
(Refer to
4-5 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 exter-
nal 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 sta-
tus data is sent from the
PCU to the CPU Unit
with every I/O refresh.
Operating data area
(Refer to
4-6 Operating
Data Area
.)
This area is for settings such as posi-
tions, speeds, and acceleration/decelera-
tion times for direct operation, origin
searches and jogging, as well as posi-
tioning sequence numbers for memory
operation. It also contains PCU status
data (see note), such as present posi-
tions and the number of the currently
executed positioning sequence.
CPU Unit’s DM or EM
area (determined by
common parameter set-
ting)
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
4-7 Memory
Operation Data
.)
This area is for settings related to mem-
ory operation, such as operation
sequences, positions, speeds, and accel-
eration/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. Set-
tings are updated when
data is transferred. The
set data is enabled and
used with the startup of
each memory operation.
Zone data
(Refer to
4-8 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. Set-
tings are updated when
data is transferred.
