Description and definition
An acronym for Programmable Multi-Axis Controller.
Computer software that is used to configure the Controller, create user programs,
and perform monitoring.
A servo motor that is driven by AC signal input. A rotating magnetic field is formed
in the motor by the input of an AC signal in order to rotate the rotor of the motor.
A control device that controls a servo motor. Upon receipt of a command from the
Controller, it switches the power by means of a power device in order to output a
power signal to drive the motor.
OMRON's unique communications method for communications between the Power
PMAC and the servo amplifier. The Power PMAC directly sends an ON/OFF signal
from the power device of the servo amplifier, while the servo amplifier sends a cur-
rent feedback value to the Power PMAC. This allows the Power PMAC to form a
current loop.
The angle of the rotating magnetic field used to rotate an AC servo motor.
Control for creating a rotating magnetic field with the required electrical angle in or-
der to rotate the motor.
The home of the electrical angle. To perform commutation control, it is necessary to
establish a phase reference at first (i.e., phase reference search).
A type of encoder that outputs SIN/COS waveforms at 1 Vpp.
A control device for controlling the angle of rotation of the mirror that reflects laser
light for scanning the position where the laser light is irradiated. It utilizes the high
response performance of the mirror to ensure high-speed trajectory control.
A type of protocol for communications with digital Galvo Scanners.
A command that sets the type of data to be sent from the Galvo Scanner to the
Controller.
A positioning stage that moves in the X-axis and Y-axis directions. Although the re-
sponse speed is slower than that of a Galvo Scanner, it can scan a larger area due
to its wide range of movement.
An acronym for Motion On The Fly. It is an algorithm that divides a position com-
mand into high frequency components and low frequency components, and distrib-
utes them to actuators with different response speeds. In this manual, the high fre-
quency components are commanded to the Galvo Scanner and the low frequency
components are commanded to the XY stage.
A laser that blinks repeatedly at a specific time interval. In contrast, a device that
constantly outputs laser light is called a continuous oscillation laser.
An oscillation method for pulsed lasers. It uses external oscillation pulse input to
obtain pulsed laser output.
An acronym for Trigger Output by Commanded distance for Rapid Processing. It
provides the function to trigger a laser output according to the distance set in the
CK3W-GC£2££.
