Automation1 XI4 Servo Interface

Description

Design Features

• Supports single connector axis interface including analog control output, encoder feedback, 2x EOT limit inputs, marker input, amplifier enable & fault, plus optional absolute encoder support
• Features up to 4 axes of 20 kHz closed-loop servo control
• Features one analog current command per axis
• Includes one axis PSO standard with multi-axis options
• Include 8/8 digital I/O (optically isolated), 1x high speed input & dedicated PSO output

Control Any Amplifier

The Automation1 XI4 servo controller brings precision Automation1 servo control to any analog transconductance amplifier. Each XI4 axis of control generates an analog voltage command -- required by analog amplifiers to control the output current to a servo motor -- and receives encoder and axis feedback signals. The XI4 comes in both 2- and 4- axis configurations, each with an independent 20 kHz servo control loop. For added flexibility, each axis on the XI4 can be configured to output clock and direction control signals. 

Automation1

The XI4 is a part of the user-friendly Automation1 motion control platform, which includes the following:

• Development software
• Controls
• Motor drives
• Fiber-optic HyperWire® communication bus

Complete Your Machine Control

Because the XI4 connects over Automation1’s HyperWire® network, the axes it controls can be coordinated with other axes on the network to deliver contoured motion and a single, simple machine control architecture.

Feedback Features

Each axis on the XI4 includes encoder feedback inputs so that you can control axis position very accurately. This input accepts incremental square-wave and absolute (optional) feedback devices. 

The dedicated axis feedback signals include encoder feedback (sine +/-, cosine +/- & marker inputs), 2x end of travel (EOT) limit switch inputs and amplifier enable and fault I/O. A dedicated digital I/O port supports 8 digital inputs, 8 digital outputs (sourcing or sinking), 1 differential high-speed input and a dedicated high-speed PSO output.

Platform Power

More than just hardware, the XI4 gives you access to the complete power of the Automation1 motion control platform. This includes the Automation1 motion development kit (MDK), the intelligent software-based controller (iSMC) and the powerful AeroScript™ programming language with integrated RS-274 G and M code support. The Automation1 iSMC can also be programmed by various controller APIs, which provide flexible methods of integrating the XI4 and the axes it controls into your system architecture.
