4. MULTIAXIS SYNCHRONIZATION
(Power Mate i–H)
MULTIAXIS SYNCHRONIZATION FUNCTION
The multi axes synchronous function allows axes (child axes) to
synchronously follow up the operation of a reference axis (parent axis)
with a certain speed ratio (gear ratio).
The features of the multi axes synchronous function are as follows:
Since the speed ratio (gear ratio) is determined by a ladder or by
specifying an NC statement, operations that frequently change the
gear ratio or the direction of movement can be performed.
The speed ratio (gear ratio) is set by specifying the amount of a
parent–axis movement and the amount of a child–axis movement
separately rather than specifying a ratio directly, so the problem of
fraction processing does not occur. As a result, the synchronization
relationship does not deviate even after rotation is performed
Axes can have a hierarchical structure not only having a parent–child
relationship but also having grandchildren and further lower levels as
long as the maximum allowable number of axes is not exceeded.
The parent–child relationship of axes is established by setting
parameters considering safety.
This function not only facilitates simplification of gears and other
mechanism but also allows the speed ratio to be changed freely during
operation, therefore enabling operations that could not be performed with
Fig. 4 shows an example in which the child axis synchronously follows
up the parent axis, and grandchild axes 1 and 2 synchronously follow up
the child axis.
