MECHATROLINK Settings Section 6-2
The station address numbers set at the MECHATROLINK device slave sta-
tions correspond to the axis numbers registered in the PCU's scan list,
regardless of the physical order in which the devices are connected to the
MECHATROLINK communications line. The scan list is set as the Common
Parameters for the PCU.
The axes are allocated eight bits per axis in the eight words of data in the
PCU's internal addresses from 183C to 1843 hex, as shown in the following
table. To allocate an axis to the Servo Drive, set the data to 40 hex and when
an axis is not used, set the data to 00 hex. (Nothing is registered for the
default setting.) Up to 16 axes can be allocated for the CS1W/CJ1W-NCF71,
up to 2 axes can be allocated for the CS1W/CJ1W-NC271, and up to 4 axes
can be allocated for the CS1W/CJ1W-NC471. An error will occur if you allo-
cate more axes than your Unit supports. The Common Parameters settings
saved in the PCU's internal flash memory are enabled when the PCU power is
turned ON or the Unit is restarted.
