PLC User's Manual - Positioning Control Edition
Description
The operation will be per-
formed at the operation
speed specified by the PLC.
The operation starts at oper-
ation speed (1) by the start
command.
If interrupt input (1) turns ON
during operation, the speed
will decelerate to operation
speed (2).
The operation will continue at
operation speed (2) until
interrupt input (2) turns ON.
The workpiece will travel to
the target position at the
specified vector speed (inter-
polation operation).
The workpiece will travel to
the specified target position
(x, y) along an arc at the
specified circumferential
speed.
The center coordinate or
radius can be specified.
A positioning control program
can be set with the table.
