Application Function

Signal

Connectivity

Position Compare & Trigger Output

Up to 20MHz encoder input frequency, hardware-based

high-speed position comparison, and trigger output, ideal for

AOI applications.

Automatic Backlash Compensation

Upon direction change, outputs backlash corrective pulses

before sending commands. This function only supports

single-axis movement.

Coordination Transformation

Often used with robotic systems, it is one of the most important

features of an advanced control system for articulated robots,

providing the ability to transform workspace coordinates to

corresponding joint coordinates.

Position Latch

The latch function captures the instant counter value of one

certain axis when the latch signal activates. The LTC channel is

used to receive the latch pulse and the latch function is

implemented with hardware.

DSP

Digital Signal Processing allows time-critical motion control,

multiple axis synchronization, and standalone control in a

variety of applications.

Manual Pulsar Input Interface

Some motion control solutions provide an interface that

connects manual pulsar input devices, which can be used to

move the axes.

Digital Encoder Input

Most feedback signals can be classified as digital pulse types

consisting of A, B phase and index signals. Normally the

frequency of digital encoder can be supported up to 20MHz

(@4xAB phase).

Ethernet Connectivity

Considering the cost and flexibility of overall automation

equipment design, Ethernet connectivity allows localization of

movement or I/O modules to save space and extend control

through adding the modules.

Field Bus Connectivity

Field Bus Connectivity localizes motion of I/O modules to save

space and extend control through addition of modules, with

dedicated I/O and Motion provided as “HSL” and “MNET”

respectively.

SIN-COS Encoder Input

To receive higher resolution of feedback position, SIN-COS

encoders appear in advanced motion systems with up to 12 bit

conversion rate.

Hardware Emergency Input

A safety protection feature providing emergency shutdown in

case of malfunction.

Analog Output /

Analog Input Channels

Some products offer analog output/

input channels for voltage signals.

Electronic Gearing

To implement multi-axis synchronization, this function sets a ratio

between multiple slave axes and one master axis to simplify

mechanism. One example is a system where two rotating drums

turn at a given ratio to each other.

Encoder Event

To accelerate the throughout of entire motion system, the

encoder event is used to triggers other axis movement

immediately when the target axis achieves the planned position.

PWM Generation

In general PWM generates pulse up to 25MHz with either fixed

frequency or fixed duty-cycle modes, and is suitable for laser,

and dispensing applications.

Electronic CAM

With electronic cam, a slave axis follows a profile that is a

function of the master position. This profile need not be salted,

but it must be an animated function, electronically command-

ing one axis position as a function of another axis with a CAM

table and fire I/O during the move.

Pitch Compensation

Irrespective of the type of ball screw system used, there always

exists the non-linear section of the whole ball screw that affects

the accuracy of overall motion. This function compensates for

pitch error in real time.
