INTRODUCTION

This document describes the functions and operation of Orca™series linear motors having

integrated drivers and an integrated sensor suite.

BLOCK DIAGRAM

Figure 1: Block Diagram

POWERING THE MOTOR

All Orca devices are powered by a DC voltage.

Flying lead power connections are provided for each motor with ring terminals by default. Most

Orca products are configured to be able to draw significant currents, up to and exceeding 40

amps, and proper attachment of the power lines to a suitable power source is important.

Suitable power sources for Orca motors are AC-to-DC converters, batteries of various chemistry,

capacitor banks, or other sources of DC voltages. Engineering support from Iris on the selection

of a suitable power source is available.

Fuse

A 30-amp fast-blow fuse must be installed between the power supply and the motor. This fuse

will be destroyed if negative voltage is applied to the motor.

Ground

In all cases, the black power lead is “Ground” and should be connected to the negative terminal of

the power supply or battery.

It is important that the power supply Ground, and the Ground of any electronics attached to the

device’s communication cable is kept at the same level. Usually this is done by making sure the

power supplies of the motor and external controller (if different) are connected to earth at both

their chassis and negative output terminal.

Chassis

As an important safety measure, the chassis of the motor must be securely connected to Earth.

Proper grounding of the chassis is also important for proper operation of the motor.

The motor enclosure and cable shields are connected but these are not connected to the Ground

circuit of the on-board electronics. Therefore, a separate connection from the Chassis to Earth

must be made which can be accommodated by threading a conductive bolt into any of the

provided thread patterns on the enclosure.

GETTING STARTED WITH IRISCONTROLS4 TM

Required Software

Orca series motors can be configured through an

integrated graphical user interface (GUI). To connect to

an Orca motor’s GUI, first download the latest version of

the IrisControls4 software on a Windows PC. The latest

release is always available here. Next, open the

IrisControls4 application. With no device connected, the

IrisControls4 window should open with an empty

console and a status of disconnected.

Once you have confirmed you have a working copy of

the IrisControls4 software you can move on to the next

section of this guide.

Required Hardware

Besides the motor itself, connecting to the IrisControls4

application requires two additional pieces of hardware

detailed below.

Connect the RJ45 communication cable from the Orca

motor to the single port side of the RJ45 splitter.

Connect the RJ45 connector end of the RS485 cable to

the splitter input labeled 1. Finally, connect the USB end

of the RS485 cable to the Windows PC running

IrisControls4.

CONNECTING TO IRISCONTROLS4TM

After ensuring your Orca is connected properly to your PC, open the IrisControls4 application. The

software will start up trying to establish a connection automatically. If the motor does not

automatically connect toggle the connect button off and press the gear icon in the top right of the

IrisControls4 window and select a baudrate of 460800 from the dropdown menu, and press

apply.

status

Using the COM selection dropdown menu at the bottom of the window, select either Orca (if it is

present) or the COM port of your USB to RS485 connection. If neither option is present, ensure

that your hardware is connected correctly as outlined in the “Getting Started” section.

Figure 7: IrisControls4 connection information

Once you have selected the correct device, press the connect button to begin attempting to

connect to the motor. If successful, the Orca GUI should launch its homepage.

NAVIGATING THE GUI

Navigation of the GUI is done using the page buttons above the console. Pressing each button

will open a different page of the GUI within the page content area. The default page upon

connection is the home page, shown below. Several other indicators, such as power draw and

mode of operation will remain visible on the GUI regardless of the page selection+

GUI PAGES

Home

The home page is the default page opened upon connecting to an Orca motor. A screenshot of

the home page is shown in figure 8. This page displays the firmware version, hardware version,

firmware build date and the motor serial number. There are no interactive elements on this page.

Position

The position page provides a real time graph displaying the target position, measured position

and target force of the motor. Below the graph, the currently set parameters of the position

controller are displayed, including proportional gain, integral gain, derivative gain and maximum

force output.

Figure 9: IrisControls4 Position page

Position and Force Graph

This graph will plot the position controller’s target position, the commanded force used to reach

that position and the measured shaft position. The left y-axis is position, and the right y-axis is

force.

The green “Target” line will show the active commanded position, but the targets for each source

(MODBUS, GUI, Kinematic Controller) are always shown on the graph as well.

Enable Position Control Button

This button will toggle the motor between Position and Sleep modes.

Zero Position Button

This button will reset the position zero point to the current physical position of the shaft.
