7.3 Example of Setting Motion Parameters for the Machine

Use incremental addition mode for an infinite length axis. In other words, the new moving amount (an incremental moving
amount) is added to the previous position reference in OL

1C and set as the new position reference in OL

1C.
It is important to note that the position reference is not necessarily set between 0 and one less than the Maximum Value of
Rotary Counter (POSMAX).

It is not necessary to consider the relationship
between OL

1C and the current position
when canceling a move. Incremental addition
mode can be used for finite or infinite length axis
type.
OL

1C does not necessarily equal the coordi-
nate value of the target position, so the position
reference can be difficult to understand intu-
itively.
Absolute mode The coordinate of the target position is specified
directly, making it easy to understand intuitively.
The current position must be set in OL

1C
whenever the power supply is turned ON or a
move is canceled. If this is not done, the axis
may move suddenly when a move command is
started.
Absolute mode cannot be used for an infinite
length axis type.
