Motion control typically refers to accurate position/velocity/torque capabilities operating in either open or closed loop modes. Open loop systems send motion commands without feedback. Closed loop systems have feedback devices to verify or adjust the resulting motion for more accurate control.
Motion control is automation that deals with the precision movement of machine components or the accurate positioning of an object, such as robot arms, rotary tables, and CNC machines. Motion control typically consists of three main components:
Numerous other mechanical components are used with motors to perform the desired motion including belts, gearboxes, ball screws, and couplings.
PLC-based motion controllers provide accurate, coordinated motion between multiple servo and/or stepper systems. These controllers can be separate units used in conjunction with a PLC, or the PLC itself can provide the motion control and high-speed I/O needed. Using the advanced capabilities of a PLC, motion can be easily synchronized between multiple axes or numerous individual motion systems can be accurately controlled.

The SureServo2 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 14 standard servo motors that can be operated in combination with one of eight standard servo drives.
The SureServo2 family includes standard accessories such as: servo motor encoder cables, servo motor power/brake cables, direct mount and DIN-rail mount I/O break-out kits for easy connection of external command and I/O signals, optional battery backup for the encoder, optional external braking resistors, and optional AC input filters.

Strain wave technology allows for a higher gear ratio and efficiency in an inline form-factor. These gearboxes are designed to work with SureServo2 and SureStep motors.
The PGA series of inline planetary gearboxes has a thread-in mounting style, along with a level of precision and torque capacity that is best in its class. The PGB series of right-angle planetary gear reducers offers similar technical specifications to the PGA series and provides an excellent solution when space and clearance requirements are limited. PGD series gearboxes with compact design and hub style output are ideal for equipment that requires high-speed, high-precision indexing movement. The LS Electric MSS series of high precision gear reducers are specifically designed to mate to LS Electric L7C & L7P series servo motors.
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 1800 oz-in of torque. SureStep Integrated stepper motors have integral encoders that allow for closed-loop control.
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 stepping system series includes:
Leadshine (R) stepper drives offer basic features and general-purpose performance. Leadshine drives work with all SureStep stepper motors to provide an even more cost-effective system.

The SureGear PGCN series is a great gearbox value for servo, stepper, and other motion control applications requiring a NEMA size input/output interface. Features include:
Motor-ready linear actuators and sliding components turn rotary motion into linear motion, providing a variety of X-Y and X-Y-Z positioning system solutions. Options for mounting stepper or servo motors as well as a full selection of accessories are available to complete a linear motion system.

Stepper motor linear actuators are stepper motors that incorporate a lead screw as the rotor, which translates motor torque into linear thrust. These actuators are often used with undriven linear slides or linear shafts/linear supports.
SureServo1 has been replaced by SureServo2 (more features, less cost). Please do not specify SureServo1 systems for new applications.
The SureServo® 1 family of brushless servo systems offers eight standard servo motors that can be operated in combination with one of three standard servo drives.
The SureServo1 family includes standard accessories such as: servo motor encoder cables, servo motor power/brake cables, ZIPLink kit for servo drive's CN1 connector, optional external regeneration resistors, and optional AC input filters.
