1.0 Introduction
1.1 Scope of the Manual
The ESP302 is an advanced stand-alone, easy to use, motion controller with up to 3
integrated motor drivers and outstanding powerful programming functionality.
It offers different operating modes through its user-friendly touchscreen front panel,
command remote ports, and web interface offering high-speed communication through
10/100/1000 Base-T Ethernet.
The ESP302 provides advanced trajectory and synchronization features to precisely
control from the most basic to the most complex motion sequences. Multiple digital
triggers provide users with additional synchronization and control features that can
improve the most demanding motion applications.
The Enhanced System Performance (ESP) architecture consists of ESP-compatible
controllers and stages. When used with ESP-compatible stages, the ESP302 plug-and-
play concept significantly increases user friendliness and improves overall motion
performance.
To maximize the value of the ESP302 Controller/Driver system, it is important that
users become thoroughly familiar with available documentation.
The present ESP302 Start-Up Manual is delivered as a hard copy with the controller.
The ESP302 Start-Up Manual, User Interface Manual, Features Manual, Programmer’s
Manual are PDF files accessible from the controller disk which can be downloaded
from the controller website under the tab Documentation.
.NET assemblies and corresponding sources are available from the controller website
under the tab Documentation -> Drivers.

2.2 Drive Options
The ESP302 controller is capable of driving up to 3 axes of most Newport positioners
using driver cards. These factory-tested drives are powered by an internal 200 W power
supply with 150 W for motion and 50 W for controller.
When used with Newport ESP stages, the configuration of the driver cards is easy using
the auto-configuration utility software.
The motor drive has the capability to drive bipolar stepper motors in microstep mode
(sine/cosine commutation)
The motor drive has been optimized for use with high-performance DC motors. It is
capable of driving DC motors in voltage mode and in current mode. All parameters are
programmable in physical units. Furthermore, the motor drive features individual limits
for the RMS current and the peak current.
2.3 Compatible Newport Positioners
The list of all compatible Newport positioners is available from the Newport catalog or
at https://www.newport.com/n/stage-and-controller-compatibility

2.5.1 Axis Connectors (AXIS 1 – AXIS 3)
Each installed axis driver card features a SUB-D25F connector to attach a cable
(supplied with every Newport stage) between the controller and a motion device.
Figure 9: Axis connectors.
Please see the next section for installation instructions.
2.6 Ethernet Configuration
Figure 10: Ethernet configuration.
2.6.1 Communication Protocols
The Ethernet connection provides a local area network through which information is
transferred in units known as packets. Communication protocols are necessary to dictate
how these packets are sent and received. The ESP302 Controller/Driver supports the
industry standard protocol TCP/IP.
TCP/IP is a “connection” protocol and in this protocol, the master must be connected to
the slave in order to begin communication. Each packet sent is acknowledged when
received. If no acknowledgement is received, the information is assumed lost and is
resent.
2.6.2 Addressing
There are two levels of addresses that define Ethernet devices. The first is the MAC
address. This is a unique and permanent 6 byte number. No other device will have the
same MAC address. The second level of addressing is the IP address. This is a 32-bit
(or 4 byte) number. The IP address is constrained by each local network and must be
assigned locally. Assigning an IP address to the controller can be done in a number of
ways (see section 3.6: “Connecting to the ESP302 through Ethernet port”).

ESP302 Controller Start-Up Manual
9 A1270B1 - EDH0411En1021 – 02/20
2.7 Sockets, Multitasking and Multi-user Applications
Based on the TCP/IP Internet communication protocol, the ESP302 controller has a
high number of virtual communication ports, known as sockets. To establish
communication, the user must first request a socket ID from the ESP302 controller
server (listening at a defined IP number and port number).
The concept and application of sockets has many advantages. First, users can split their
application into different segments that run independently on different threads or even
on different computers.
Second, the concept of sockets has another practical advantage for many laboratory
users since the use of threads allows them to share the same controller for different
applications at the same time. With the ESP302, it is possible that one axis of the
ESP302 controller for an optical delay line, while another axes are simultaneously used
for a totally different application. Both applications could run completely independent
from different workstations without any delays or cross-talk.

3.0 Getting Started
3.1 Unpacking and Handling
It is recommended that the ESP302 Controller/Driver be unpacked in your lab or work
site rather than at the receiving dock. Unpack the system carefully; several cables are
included with the equipment. Inspect the box carefully for loose parts before disposing
of the packaging. You are urged to save the packaging material in case you need to ship
your equipment.
3.2 Inspection for Damage
ESP302 Controller/Driver has been carefully packaged at the factory to minimize the
possibility of damage during shipping. Inspect the box for external signs of damage or
mishandling. Inspect the contents for damage. If there is visible damage to the
equipment upon receipt, inform the shipping company and Newport Corporation
immediately.
WARNING
Do not attempt to operate this equipment if there is evidence of
shipping damage or you suspect the unit is damaged. Damaged
equipment may present additional personnel hazard. Contact
Newport technical support for advice before attempting to plug in
and operate damaged equipment.
3.3 Packing List
Included with each ESP302 controller/driver are the following items:
•Power cord.
•Straight-through Ethernet cable, black, 5 meters.
•ESP302 Start-Up Manual.
If there are missing hardware or have questions about the hardware that were received,
please contact Newport.
3.4 System Setup
This section guides the user through the proper set-up of the motion control system. If
not already done, carefully unpack and visually inspect the controller and stages for any
damage. Place all components on a flat and clean surface.
WARNING
Before operating the ESP302 controller, please read chapter 1.0 very
carefully.
CAUTION
The ESP302 controller includes several protections against wiring
and configuration errors. However, attempting to operate with wrong
connections or parameters may lead to material damage.
CAUTION
No cables should be connected to the controller at this point!

3.4.1 Rack Mounting Kit
The ESP302 controller is basically intended to be installed on a flat surface such as a
table or a cabinet shelf.
A rack mounting kit can be provided separately to properly secure the controller in a
standard 19" electronic enclosure. It is composed of two brackets and handles that can
be easily attached on the sides of the controller. Both orientation mountings are possible
as shown below.
