Axis Parameter Area
Section 4-4
Number of Communications Retries
This parameter is used to set the maximum number of stations that will per-
form communications retries when sending/receiving data between the PCU
and MECHATROLINK devices.
Set value: 0 to 7, F
The default setting 0 is the same as when the number of retries is set to 1.
When F is specified, the number of retires is 0 (no retries).
C2 Master Connection
This parameter is used to set whether a separate communications master is
connected to the PCU for MECHATROLINK system support. This parameter
will be used for connecting future system support devices. Do not change the
default setting of 0 (no C2 master).
0: No C2 master (default setting)
1: C2 master connected
Setting Example
Default Settings
1856 hex: 0000 hex
1857 hex: 0000 hex
The MECHATROLINK communications settings are as follows:
Transfer cycle: 1.0 ms
Communications cycle:
×
3 (1.0 ms
×
3 = 3.0 ms)
Number of communications retries: 1
There is no C2 master.

Axis Parameter Area
The Axis Parameter Area is used to make settings for axis control, such as
origin input signal selection and origin search method. The axis parameters
for the axes to be used must be set.

Axis Parameters Overview
Axis 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. Turn ON the power to the CPU Unit again, or restart the PCU
to read the Axis Parameters saved in flash memory to the PCU's internal
memory.
The Axis Parameters can be changed at any time by sending the WRITE
DATA command to the PCU. The changed parameters are enabled as soon
as the data has been written without any errors. The addresses in the PCU's
internal memory allocated for Axis Parameters are determined by the axis
number of each axis using the following equation.
