4-3 Common Parameter Area
Common Parameters are used for basic settings for operating the PCU, such
as allocation of the Axis Operating Memory Areas and settings for MECHA-
TROLINK communications. The common parameters must be set when using
the PCU.
4-3-1 Common Parameters Overview
Common Parameters are transferred to the PCU's internal memory using the
data transfer command and saved in the PCU's flash memory using the SAVE
DATA command. After setting and saving the Common Parameters, either
cycle the power to the CPU Unit, or restart the PCU. This operation will enable
the set parameters. The Common Parameter Area is used to set the following
information.

1838 hex Axis Operating Output Memory Area desig-
nation Specifies the area allocated for the Axis Operating Output
Memory Areas.

00B1 hex: Work Area 00B2 hex: Holding Area
00B3 hex: Auxiliary Area 0082 hex: DM Area

1839 hex Beginning word of Axis Operating Output
Memory Areas Specifies the beginning word of the Axis Operating Output
Memory Areas.
The beginning word of the Operating Output Memory Area for
Axis 1 is determined by the Axis Operating Output Memory
Area designation and the word determined using this parame-
ter. Each Axis is allocated 25 words in sequence from this
word.
183A hex Axis Operating Input Memory Area designa-
tion Specifies the allocated area and beginning word for the Axis
Operating Input Memory Areas.
The setting method is the same as for the Axis Operating Out-
put Memory Areas.
183B hex Beginning word of Axis Operating Input
Memory Areas
183C hex to
1843 hex Scan list Sets the axis allocations for axes 1 to 16 with 8 bytes per axis,
as follows:
00 hex: Axis not used (default setting)
40 hex: Allocates axis to the Servo Drive.
1856 hex Transfer cycle Communications
cycle Transfer cycle:
00 hex: 1 ms (default setting)
01 hex: 1 ms
02 hex: 2 ms 03 hex: 3 ms
04 hex: 4 ms 05 hex: 5 ms 06 hex: 6 ms
07 hex: 7 ms 08 hex: 8 ms A2 hex: 0.25 ms
A5 hex: 0.5 ms
Communications cycle:
Sets a multiplier used to obtain integer multiples of the trans-
fer cycle.
Set value: 00 to 20 hex
The default setting 00 is the same as when the cycle is set to
3.
Set as follows:
Transfer cycle x communications cycle (multiplier)
