Device setup
(For offline parameters)
The PCU's Common Parameters and Axis Parameters are written from the
CPU Unit using the WRITE DATA Bit in the Common Operating Memory Area.
The data to be transferred is set by specifying the number of transfer words,
transfer source, and transfer destination in the Common Operating Memory
Area. Multiple parameters can also be transferred all at once.
The PCU reads the contents of the Common Parameters and Axis Parame-
ters saved in the internal flash memory when the PCU power is turned ON or
the Unit is restarted, and enables them as operating parameters. Parameters
transferred to the PCU using the WRITE DATA Bit will be lost if the PCU power
is turned OFF or the Unit is restarted.
(1) The Common Parameter set values are enabled by cycling the PCU pow-
er or restarting the Unit after executing WRITE DATA. Therefore, when
the WRITE DATA Bit is used to change the contents of the Common Pa-
rameters, execute SAVE DATA and save the Common Parameters to the
PCU's internal flash memory.
(2) The Axis Parameter settings are enabled when WRITE DATA execution
has completed. To change Axis Parameter settings permanently, execute
WRITE DATA followed by SAVE DATA (while MECHATROLINK commu-
nications are stopped) to save the Axis Parameter settings in the PCU's
internal flash memory.
(3) Execute WRITE DATA to write data to the PCU while the Data Transfer-
ring Flag is OFF. Writing data to the PCU is disabled while the Busy Flag
