Key Features

Motion Function

Program Language

Control

Home Return Modes

To ensure motion repeatability, the mechanism must reset to the

zero-position via the dedicated sensor point “ORG”, normally

completed by combining “ORG”, “EL” and “Index” signals.

Helical Interpolation

If the start point and destination of a circular interpolation

movement lie on different planes, a helical function is required

to directly regulate the movement.

T-Curve / S-Curve Velocity Profile

Acceleration and deceleration times are programmable, and

rates can be set individually, with S-curve motion compensating

for generated mechanical vibration.

Continuous Move (Contouring)

Continuous movements comprise a range of linear and circular

interpolated paths. Point-Table functions support hundreds of

paths to smooth the velocity of continuous movement supported

by included velocity planning software..

Path Blending

Anticipating sharp corners and small arc path execution, path

blending is required to decelerate automatically and ensure

smoothness of the velocity at junctions of two linear paths.

Program Download

To ensure real-time control performance, programs are

downloadable into onboard processors, with support for up to 8

tasks.

Virtual Axes

To implement multi-axis synch or following motion, virtual axes

act as a model to synchronize the motion of selected axes.

PID Plus Feedforward Gain Control

All servo applications require specified safe and stable PID loop

parameters in order to perform position control, ADLINK

Softmotion provides a proportional-integral-derivative (PID)

algorithm with adjustable acceleration and velocity and

feed-forward gain to simplify servo application development..

Frequency Response Analysis

A bode plot is a graph of the transfer function of a linear,

time-invariant system versus frequency, plotted with a

log-frequency axis, to show the system's frequency response and

find the cutoff frequency defining the 2nd notch filter to reduce

resonance.

Speed Override

Changes rotation speed on-the-fly while the axis is running.

Linear and Circular Interpolation

To complete multidimensional motion, any 2, 3, or even all 6

axes are required for linear interpolation and any 3 axes can

execute circular interpolation.

Synchronization

Simultaneous start/stop can be executed on multiple axes in

one card, or multiple axes across multiple cards, using software

or external input signals. This feature is especially beneficial for

complicated motion patterns requiring absolute synchronization

of multiple axes.

Velocity Planning

Velocity planning is required to smoothly implement continuous

movement and reduce vibration. The velocity of each path is

generated automatically according to corner angles of

complete paths.

IEC 61131-3

The third section of the open international standard IEC 61131

for programmable logic controllers, CODESYS (provided by 3S

enterprise) is integrated into specific ADLINK motion controllers.

G Code

Commonly used designation for the most widely used CNC-like

programming language, with many implementations. Used

mainly in automation, it is part of computer-aided engineering.

G-code directs CNC where to move, how fast to move, and

along what path.

Auto-tuning

In order to reduce tuning efforts and acquire accurate PID

parameters, auto-tuning applications are provided in ADLINK

dedicated software, allowing conditions to be configured

according to real application requirements.

Position Override

After movement begins, the position target can be changed

on-the-fly even if the motion reaches maximum velocity.
