Automation1 XI4 Servo Interface
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.

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:
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.
