Automation1 SI4 Stepper Controller

Description

Design Features

• Supports single connector axis interface including clock & direction output, encoder feedback, 2x EOT limit inputs, marker input, amplifier enable & fault, plus optional absolute encoder support
• Features new closed-loop stepper control (pending)
• Features one clock output (up to 25 MHz) & direction output per axis
• Includes with 8/8 digital I/O (optically isolated), 1x high speed input

Automation1

The SI4 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 SI4 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 clock and direction output axis on the SI4 includes encoder feedback inputs so that you can verify accurate positioning. This input accepts incremental square-wave, absolute and (optional) incremental sine-wave encoder signals.  

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) and 1 differential high-speed input. 

Platform Power

More than just hardware, the SI4 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 SI4 and the axes it controls into your system architecture.
