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.
- Eight standard servo systems from 100W to 3kW
- Use with AutomationDirect CLICK, DirectLOGIC, or P3000 PLCs; or any other host controller
- Servo Drives feature on-board indexer and adaptive tuning modes
- Free set-up software (SureServo Pro software available as a free download, or on CD)
- 30 day money-back guarantee
- Everyday low prices and same day shipping
- 2 year warranty
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.
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.

SureGear™ Precision Gearboxes for Servomotors
The SureGear PGA series of high-precision servo gear reducers is an excellent choice for applications that require good accuracy and reliability at an exceptional value. This in-line planetary
gear reducer has a thread-in mounting style, along with a level of precision and torque capacity that is best in its class.
- Industry-standard mounting dimensions
- Thread-in mounting style
- Best-in-class backlash (5 arc-min)
- Four gear ratios available (5, 10, 15, 25:1)
- Mounting hardware included for attaching to SureServo motors
- Helical-cut planetary gears for quiet operation and reduced vibration
- Uncaged needle roller bearings for high rigidity and torque
- Adapter bushing connection for simple and effective attachment to most servo motors
- High-viscosity, anti-separation grease does not migrate away from the gears; no leakage through the seal
- Maintenance free: no need to replace the grease for the life of the unit
- At nominal speed, service life is 20,000 hours
- Can be positioned in any orientation
- 5-year warranty
The SureGear PGA series easily mates to SureServo motors, and is the perfect solution for applications such as gantries, injection-molding machines, pick-and-place automation, and linear slides.

SureStep™ - Stepper Systems
SureStep™ is an open-loop stepping system that provides simple and accurate control of position and speed and
offers a low cost motion control solution with up to 1200 oz-in of torque.
- 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 Standard stepper drive to allow very precise motion control.
- The Advanced stepper drives also accept pulse inputs, but they also can be commanded by an analog speed signal or by serial communication.
- 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:
- Two DIP-switch configurable microstepper drives
- Two software configurable advanced microstepper drives
- Two braking accessories
- Four step motor power supplies
- Twenty stepper motors (NEMA 17, 23, 34 frame sizes)
- now available in single and dual-shaft models ... New!
- Two stepper motor extension cables
- New! ... SureStep $89.00
Drive, STP-DRV-6575
- New! ... SureStep Regen Clamp, STP-DRVA-RC-50
- New! ... SureStep External Load Resistor, STP-DRVA-BR-100
- New! ... STP-PRO v1.02 SureStep Pro Software is available as a free

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)
