7-10-2 Overview
PLS2 instruction enables the execution of virtual pulse output with trapezoidal
acceleration/deceleration (virtual pulse output mode).
PLS2 instruction executes the pulse output with trapezoidal acceleration/
deceleration internally. At the same time, it integrates (counts) the pulse
amount (an area) for the trapezoid internally.
With this function, the "virtual axis position" defined by the internal pulse
counts can be applied to various applications.
Ex 1) Position/speed
Control Corresponding to
Virtual Axis (Electronic
Cam Operation) The internal pulse counts being defined as a virtual axis, it is possible to exe-
cute the electronic cam operation (position and speed control corresponding
to the virtual axis angle) based on the approximated curve corresponding to
the virtual axis.
Ex 2) Electronic Gear
Corresponding to the
Calculated Speed of the
Virtual Axis (Pulse
Synchronous Control) The internal pulse counts being defined as a virtual axis, the unit calculates
the speed of the virtual axis with such a ladder program. The value (speed)
with a certain multiplication can be output as a pulse (Electronic gear func-
tion). This enables the synchronous control based on a virtual axis.
