Motion Controller & Driver, 2-Axis, Ethernet, RS232
Model: ESP302-2N
Product Series Overview
ESP302 3-Axis DC and Stepper Motion ControllerThe ESP302-2N Dual Axis Motion Controller and Driver is the successor of the popular ESP301 motion controller providing the same functionality as the ESP301 with an Ethernet interface, web base GUI, and enhanced front panel functions through LCD Touch Screen. For maximum backward compatibility, the ESP302 features the same motion commands and control algorithms as the ESP301.
Integrated Drivers
The ESP302 controllers feature up to 3 integrated drivers for various stages. These drivers support 2-phase stepper or brush DC motors up to 3A, 48V per axis. Built-in drivers make the ESP302 controllers a space saving and cost effective choice.
User-Friendly Front Panel
ESP302 includes a user-friendly LCD touch-screen front panel interface providing an intuitive menu system from which you can execute motion programs, initiate manual moves, and configure operating parameters. Positions for all axes are displayed on the LCD screen. This allows users to perform nearly all functions without connecting to a computer.
Website Interface
Through its 10/100/1000 Base-T Ethernet port, the ESP302 offers a website interface for users to control its most common features and functions. This high-speed interface is compatible with Windows 7 and above, is independent from the user's operating system and does not require specific software on the host PC.
Plug-and-Play with ESP Compatible Stages
When an ESP-compatible stage is connected to the ESP302 controller, the stage is quickly recognized and operating parameters are configured without the need for user inputs. This Plug-and-Play feature is not only transparent to the user, but it also ensures the safe operation of the stage.
Functional Motion Capabilities
The ESP302 controllers include a variety of motion capabilities: Slaving (joystick or other stage), Jogging, Point-to-Point, Grouping, Trapezoidal Velocity Profile, S-Curve Velocity Profile, Backlash Compensation, and Linear Compensation. These motion features make the ESP302 well-rounded controllers that can handle common motion tasks.
Standard Communication Protocols
The ESP302 offers 2 widely-used communication protocols for computer interfacing. Standard Ethernet and RS-232-C communication link is used for easy computer interfacing. An optional IEEE-488 (GPIB) interface adapter can be used for high speed parallel communication.
Please note that our RS232 connector (SUB-D15HD) is not the standard subD9. Please use: ESP302-RS232 Serial Communications Adapter (newport.com) to convert the signals to a standard 9-pin D-SUB RS232 serial port connection.
