1. Overview

The Motor Sizing Tool (MST) helps to select the appropriate motor and drive from the
mechanical structure in which the motor is to be used, and from the operating patterns, mass,
reduction ratio and other properties of the various components required to calculate inertia
and torque. Various functions have been incorporated into this program to make it easier to
select an OMRON motor and drive to aid in producing higher quality systems in response to
this demand from the customers.

OMRON Motors and Drives models data are contained in a database, making it possible to
select the optimum motor without having to input data.

This manual describes the operating procedures of the Motor Sizing Tool.

4. Creating a new project

Once the user initially executes the application, the splash screen appears and after that, the
tool starts up. The aim of the splash screen is to inform the user that the software is loading.
See Fig. 5.

Fig. 5 Start-up Window

4.1. Wizard Window

After the user starts the application, no project is loaded and a popup wizard window is
shown to guide the user with a set of steps that must be completed in a sequential order. The
conceptual appearance of this window is:

- List of the steps, where the current step is highlighted. The steps still to be edited are
unmarked.

- ‘Next’ and ‘Back’ buttons allow navigating within the wizard project steps.

- ‘Finish’ button closes the window and goes to main screen with a default project
configuration.

- ‘Cancel’ button closes the window and goes to main screen with no project opened.

The wizard process consists, firstly, of a welcome step and different followings steps
according to which type of project wants to be created -Lite or Full-.

- Welcome Step: asks for ‘New Lite project’, ‘New Full project’ or ‘Open project’.
See Fig. 6.

o New Lite project: will follow the wizard in order to build a Lite project. A Lite

project is a project in which the axis chains contained in a machine are
protected in terms of components (not possible to modify predefined axis) but
some fields are editable. Lite projects present the following details:

▪ Can only create “Lite projects”
▪ Can only open “Lite projects”.
▪ Can only save opened projects as “Lite project”

Operation Manual - page 10/37

o New Full project: will follow the wizard in order to build a Full project. A Full

project is a project in which the axis chains in which the axis chains contained
in a machine are fully editable in terms of components and fields. Full projects
present the following details:

▪ Can only create “Full projects”.
▪ Can open “Lite projects” and “Full projects”.
▪ Can only save opened projects as “Full project”

o Open project: allows select an existing project (*.omst) and, after that, the tool

will go to main screen with the project opened.

Fig. 6 Welcome Window

- Project information Step: request of project, author and customer information. The
project name must be specified, but even if the other information is not set, it will not
affect the operation of the application. See Fig. 7.

o Main project data: name, date, comment.
o Author data: name, department, mail.
o Customer data: name, identifier, company, mail, phone, address.

Fig. 7 Project information Window

Author data persists after to reinitialize a new project.

Operation Manual - page 11/37

- Machine information Step: request information of machine, device model and
version of the controller, and the type of power supply. A list of available controllers is
displayed. The generic model can be selected when a third party controller is used.
Each machine is associated to one controller. See Fig. 8. This step is by-passed for
Lite projects.

o Machine data: name, number, picture.
o Controller: name, device model & version, power supply.

Fig. 8 Machine information Window

- Axes information Step: asks for the general configuration of the machine. The
‘Predefined axes’ must be inserted into the defined machine. See Fig. 9.

o A list of predefined axes is available.

Fig. 9 Axes information Window

After these steps are finished, the configured project is built.

4.2. Main Window

After finishing the wizard process, the software goes to the main screen with the skeleton of
the configured project and with the machine view as a background.

As a general view, the user interface of the application has the following control and function
elements. By default, the windows are arranged in a similar structure shown in Fig. 10.

Motor Sizing Tool v1.40, 2019

Operation Manual - page 12/37

For Full projects two tool anchorable toolbars will be available at top right: Axis toolbox and
Machine toolbox. In case of Lite projects, the Axis toolbox is not available, and the Machine
toolbox is always shown.

Fig. 10 Main window

It’s possible to create customizable layouts. By clicking and dragging, the windows can be
docked, undocked, floated, auto-hidden, or moved to new locations. Next Fig. 11 shows this
functionality.

Fig. 11 Dockable windows

4.2.1. Toolbar

By clicking the items in the toolbar, which is partially shown in Fig. 12, the user can directly
invoke the most frequently used functions. The toolbar is split in three tabs.
