Precision Motion Controllers and Drivers for Positioning Systems

Servo Motors, Stepper Motors, Brushless Motors, Linear Motors and Piezo Motors

PI provides a large variety of hardware & software solutions for high precision motion control. Our portfolio spans from integrated compact single axis servo controllers / drivers, such as popular Mercury-class motion controllers, to complex multi-axis systems for parallel-kinematics positioners, such as hexapods. 

Examples of Custom Motion Systems / Precision Automation 

ACS Advanced Industrial Controllers 
PI recently acquired the majority shares of ACS Motion Control. Together with ACS, a plethora of controllers and drivers for virtually any type of motor drive can be offered: three phase, DC, brushless, stepper, ultrasonic, piezo-stick-slip, piezo-walk, linear-servo, high-speed voice coil, and, of course, piezo controllers for flexure-guided precision nano-positioners. 

OEM cards, rack-mount solutions and custom motion controllers with hundreds of axes are available.

Advanced Motion Controllers for 3-Phase Motors and Air Bearing Stages

These high performance controllers feature state of the art ACS SPiiPlusEC motion control modules and EtherCAT® master, and includes ServoBoost™ for up to eight axes of motion. ServoBoost™ provides better, more consistent servo performance that is insensitive to noise or (load) changes in the system.

This series of motion controllers from PI offers a completely integrated electronics solution, with controller, drives, and power supplies packaged together. The A-81x is in a compact 19-inch rack-mount enclosure for 1, 2, or 4 axes of motion, while the slightly larger A-82x is capable of controlling 4, 6, or 8 axes. These controllers are designed and optimized to work with the PIglide line of air bearing stages which feature direct drive linear and rotary servo motors and high resolution encoders.
