SureServo™ - AC Servo Systems
The AutomationDirect SureServo family of brushless servo systems is fully digital and offers a rich set of features to cover a broad range of motion control applications. There are eight standard servo motors that can be operated in combination with one of three standard servo drives.

The servo drives can be configured for a range of command sources including analog torque, analog velocity, "step & direction" or "up & down" pulse position, quadrature encoder follower, and built-in motion controller with preset position, velocity, or torque. Presets can be selected with switch inputs or modified with the MODBUS serial interface. Configuration and diagnostics of the servo drives can be accomplished with the integrated keypad/display or the easy-to-use PC-based FREE SureServo Pro software.

The SureServo family includes standard accessories such as: servo motor encoder cables, servo motor power/brake cables, ZIPLink kit for servo drive's CN1 connector that provides for easy connection of external controller and I/O, optional external regeneration resistors, and optional AC input filters.

SureServo Servo Systems Overview

SureStep™ - Stepper Systems
SureStep™ is an open-loop stepping system that provides simple and accurate control of position and speed and offers a motion control solution for applications requiring lower power.

Programmable logic controllers (PLCs) or other indexers and motion controllers act as a stepper motor controller to send step pulses and direction signals that are received by the stepper drive to allow very precise motion control.
The SureStep stepper motor, microstepper drive and power supply products provide a low-cost, reliable, high quality solution to answer your positioning and motion control needs.

The SureStep stepping system series includes:

One DIP-switch configurable microstepper drive
Two software configurable advanced microstepper drives
Four step motor power supplies
Nine stepper motors (NEMA 17, 23, 34 frame sizes)
Two stepper motor extension cables
FREE stepper configuration software

SureStep Stepper Systems Overview

What is a Motion Control System?

Motion control is typically considered to be the industrial automation field of controlling the position and/ or velocity of some type of actuator, usually an electric motor. Motion control is a very important component of robotics applications, but it is also used extensively in many other industrial applications where the motions are less complex. Non-robotic applications are often referred to as General Motion Control (GMC). For example, motion control systems are used widely in the packaging, printing, manufacturing and assembly industries, as well as many others. Common motion control product manufacturing applications include conveyor system controls, food processing, or other material handling applications.

Typical motion control system architectures include:

A motion controller to generate the trajectory and close the position loop, sometimes also the velocity loop (this is referred to as servo control).
Servo can also refer to servomechanism - which is a device used to cause mechanical motion for a specific distance.
A drive or amplifier to transform the velocity or torque signal into a high power electrical current
A motor for actuation
Some mechanical device such as a gearbox
A feedback sensor to return the motor position to the motion controller and the drive or amplifier

Why Use A Servo System? (vs. a lower cost Stepper System)

The SureServo AC servo systems provide the highest possible level of performance for precise control of position, velocity, and torque. As compared to lower cost stepping systems, the AC servo products provide:

More torque at higher speeds (up to 5,000 rpm)
Broader range & higher power (up to 3kW)
Higher response with closed-loop control (high hit rate without stalling or lost position)
