Common Parameter Area
Section 4-3
Axis Operating Input Memory Area Designation:
Specifies the words allocated for the Axis Operating Input Memory Areas.
The setting method is the same as for the Axis Operating Output Memory
Areas.
Beginning Word of Axis Operating Input Memory Areas:
Specifies the beginning word of the Axis Operating Input Memory Areas.
The setting method is the same as for the Axis Operating Output Memory
Areas.
Note (1) Set the beginning word of the Axis Operating Output Memory Areas and
Axis Operating Input Memory Areas in the Common Parameters so that
the words allocated to each area do not exceed the upper limit of the
range for each of the CPU Unit's I/O memory areas.
CPU Unit I/O Memory Areas
CIO Area:
CIO 0000 to CIO 6143
Work Area: W000 to W511
Holding Area: H000 to H511
Auxiliary Area: A000 to A959
DM Area:
D00000 to D32767
EM Area: E
@
_00000 to E
@
_32767 (

= EM Bank No.)
The maximum set value for the beginning word of the Axis Operating Out-
put/Input Memory Area is calculated as follows:

(2) If the setting exceeds the range of the I/O memory area, an Initialization
Common Parameter Check Error (Unit error code 0028) will occur when
the PCU power is turned ON or the Unit is restarted.
Example:
Beginning word of the Axis Operating Output Memory Area: CIO 6100
Connected axes: 2 min.
Axis 1: Output Area: CIO 6100 to CIO 6124
Axis 2: Output Area: CIO 6125 to CIO 6149
The highest word in the CIO Area is CIO 6143. Therefore, an error will
occur.
(3) If the ranges set for the Axis Operating Output Memory Area and Axis Op-
erating Input Memory Area overlap, an Initialization Common Parameter
Axis 1 No. 1
Axis 2 No. 2
Axis 3 No. 3
Axis 4 No. 4
Axis 14 No. 14
Axis 15 No. 15
Axis 16 No. 16
