Motion Controllers

What Is a Motion Controller

A motion controller is a dedicated control device that calculates and executes motion trajectories for one or more mechanical axes. It receives feedback from position sensors such as encoders or resolvers and continuously adjusts output commands to motors or drives to achieve precise motion profiles.

Motion controllers operate in closed-loop systems, allowing continuous correction for position error, load variation, and mechanical disturbances. This closed-loop operation enables high precision and stability in demanding motion applications.

Motion Controller Architecture and Operation

Motion controllers are built around real-time processing architectures optimized for deterministic control. Core components typically include:

• Real-time processor or dedicated motion control ASIC
• Trajectory planning engine for position and velocity control
• Feedback processing for encoders, resolvers, or linear scales
• Control loops for position, velocity, and torque
• Communication interfaces for integration with drives and automation systems

These components allow the controller to execute complex motion sequences while maintaining tight synchronization across multiple axes.

Types of Motion Controllers We Offer

Single-Axis Motion Controllers

Single-axis motion controllers are used for simple positioning tasks such as linear stages, rotary tables, and pick-and-place mechanisms. They provide precise control over one motor or actuator and are commonly used in laboratory equipment and compact automation systems.

Multi-Axis Motion Controllers

Multi-axis motion controllers coordinate the movement of multiple motors simultaneously. They are essential for applications requiring synchronized motion, such as robotics, gantry systems, CNC machines, and semiconductor processing equipment.

These controllers support coordinated trajectories, interpolation, and real-time axis synchronization.

Servo Motion Controllers

Servo motion controllers are designed to work with servo motors and high-resolution feedback devices. They provide high dynamic performance, fast response times, and accurate positioning for precision motion systems.

Servo controllers are widely used in robotics, automation, and high-speed manufacturing environments.

Stepper Motion Controllers

Stepper motion controllers control stepper motors for applications where simplicity and cost efficiency are priorities. They are commonly used in positioning systems, inspection equipment, and light industrial automation.

Embedded and Modular Motion Controllers

Embedded and modular motion controllers integrate motion control functionality into compact hardware platforms. These systems are often used in test equipment, OEM machinery, and distributed automation architectures.

Key Technical Parameters Engineers Evaluate

When selecting a motion controller, engineers evaluate several critical performance parameters:

• Number of controlled axes
• Positioning accuracy and repeatability
• Supported feedback devices and resolution
• Control loop update rate and latency
• Communication protocols and fieldbus support
• Motion programming capabilities
• Safety features and fault handling

Selecting a controller with the correct performance characteristics is essential for stable and precise motion control.
