Operating Memory areas of the PCU consist of Output Memory areas that issue commands to
start functions, and Input Memory areas that correspond to respective Output Memory areas.
The applicable Input Memory areas indicate 5 statuses that include command reception,
executing, command disable, completed successfully and error.
Note, however, that not all 5 statuses are available depending on the function.
The table below shows basic function memory areas.
In addition to the above, these Command Memory areas also use the executing, command
invalid and completed successfully statuses.
This memory area turns ON when an
operation or function starts.
Response status to the ON/OFF switching of
a Command Memory area according to the

command reception to hold the status.
This status indicates that the command
function is currently executing.
It is used as an interlock if executing a different
function during processing generates an error.
This status indicates that the executed
command failed because it did not meet the

This status turns ON when you could not start
operation due to an error at the start of the
command or because of the priority of the
