Outline of Operation
Direct Operation Command Memory area
Axis status Memory area
Synchronous data refresh output area
Synchronous feeding is a function to allow the CPU to give a command position to each PCU
sequentially via synchronous data refresh so as to perform positioning operation in control
cycles that correspond to the synchronous cycle time.
While [Synchronous Feeding Bit] in the Direct Operation Command Memory area is ON, this
function outputs the movement amount which is required to perform positioning in the cycle of
the next synchronous cycle time.
Set the movement amount by using an absolute position in the Synchronous Data Refresh
area which you specify as the synchronous feeding command position data of each PCU axis.

In synchronous feeding, the maximum speed set in an axis parameter is disabled.
the synchronous feeding command position data from the present position for each cycle of
synchronous cycle time. Accordingly, abrupt movement may occur depending on the command
position which is given to the synchronous feeding command position data.
