Trapezoidal & S-Curve Proﬁle

Users can issue commands to conﬁgure movement proﬁles (initial

speed, acceleration, deceleration, maximum speed and acceleration

onset rate (or called jerk which is for S-–speed-curve movement))

and control a motor to move based on predeﬁned speed curves such

as the trapezoidal curve or S-curve (second degree curve).

Homing

SoftMotion supports more than 10 homing modes to ﬁt into the mechanical design.

Programmable Acceleration and Deceleration

Programmable to deﬁne the rate of acceleration and deceleration

and conﬁgure acceleration curve proﬁle (the initial speed, maximum

speed, acceleration, deceleration, Jerk) that best meets user needs.

Acceleration and deceleration rates can be set independently to

ensure the movement better & smooth!

SoftMotion Introduction

Advantech’s SoftMotion Introduction

SoftMotion is Advantech’s important core technology in the equipment automation ﬁeld. Compared to ASIC motion control solutions, Advantech’s Machine Automation Team

independently developed its own SoftMotion control technology and uses the FPGA (Field Programmable Gate Array) and DSP (Digital Signal Processing) as the core-computing

hardware platform. Because of SoftMotion, which is developed into the software architecture, excludes the inherent limitations of ASIC speciﬁcations Advantech is able to offer the

expertise of professional motion control for our customers and provides custom ﬁrmware to optimize customer’s devices control as well as to minimize their needs for programming.

Through SoftMotion technology enhancements, Advantech offers critical technologies in EMA (Electronic Machine Automation) and TMA (Traditional Machine Automation) ﬁelds.

Meanwhile, based on the three motion control architectures (centralized, distributed and embedded), Advantech’s comprehensive product offering helps our customers to continuously

progress their technologies, so as to create a win-win opportunity.

Supporting Advantech’s PCI-1245/1245E/1245L/1265/1285/1285E series, SoftMotion’s features are described below:

JOG Move

Manually control the axis to directly move within a ﬁxed (predeﬁned)

amount of position or continuously in the +/- direction along all axes

via external signals; with this feature, users can manually control

the movement while reducing CPU loading without consuming

system resource.

Handwheel Move

Use a handwheel to control a motor to rotate positively or negatively;

also, users can deﬁne parameters for or use external handwheels to

control axial movement.
