Cam Designer Basic

Introduction

4 Introduction

»Cam Designer Basic« is a graphic tool for the easy creation of electronic cams.

»Cam Designer Basic« provides the features of the »Cam Designer Professional« in reduced form.

Main features of the »Cam Designer Basic«

Easy creation of cams by means of graphic objects (e.g. lines, polynomials).

Data is directly input using the physical unit.

Display of speed, acceleration torque and jerk.

Printing of the cam graphics with project information and date.

Main features of the Software Package - Cam

48 profiles can be stored in the PLC

289 base points per profile in the relative data model

116 base points per profile the absolute data model

Increased number of the available base points with reduced number of profiles reserved

48 cam groups can be stored

Three tracks per cam group

Four cams per tracks

Main features of the 9300EK servo cam

8 profiles can be stored in the PLC

256 base points per profile in the relative data model

64 base points per profile the absolute data model

Note!

No names are used for profiles and projects in the documentation. The examples use the names assigned by the system. You can assign names on your own in your system.

The »Cam Designer Basic« is a product of the Software Package - Cam. It manages the relevant data of the machine and also creates projects. However, it lacks the »Cam Manager« and hence the ability of managing several products at the same time.

Introduction

Entries via the »Cam Designer Basic«

The project

Only one product at a time is available, i.e. only one product at a time can be processed.

–Names of the axes

The feed constant and gearbox factor of each axis

Scaling of the axes for profile creation

The master axis

–Number of cycles of the machine

The value is a rated value and can maximally amount to 199% during operation.

The slave axes

–Number of profiles to be stored

–Number of base points to be assigned

–Selection of the data model

The product (profiles)

Note!

No names are used for projects and products. The names given by the »Cam Designer Basic« are continued to be used. You are able to select the names on your own in your project.

Cam Designer Basic

Introduction

Advantages of »Cam Manager«

the »Cam Manager« is not included in the »Cam Designer Basic«.

The management of projects with several products and the corresponding axes using the »Cam Designer Basic« is only possible with a directory structure.

The »Cam Designer Professional« manages the projects using the integrated »Cam Manager«.

The assignment between products and axes is displayed in the »Cam Manager«.

The products and axes are stored and managed automatically in the »Cam Designer Professional«.

The storage and management of the products and axes in the »Cam Designer Basic« are provided by means of the *.LCx-files and *.cam-files

–LC9 for Servo PLC and ECS EA

–LC7 for 9300 EK servo cam

Cam Designer Basic

Introduction

Motion tasks

4.1Motion tasks

According to the VDI 2143 with the title "Motion rules for cam mechanisms" the motion tasks can be classified as follows:

Motion task	Abbreviation	Speed in the	Acceleration in the	Graphical
		boundary point	boundary point	representation
Break	R	v = 0	a = 0	Line

Constant speed	G	v ≠ 0	a = 0	Line

Reversal	U	v = 0	a ≠ 0	Point

Motion	B	v ≠ 0	a ≠ 0	Point

These four motion tasks serve to formulate the technological specifications for all problems relevant to practice.

For calculating the profile segments between the defined sections, the boundary values of the specifications are required.

Since the acceleration for R and G is = 0, these two motion tasks can be described linearly. The boundary values on the left and right connection are identical in this case.

The acceleration for U and B is ≠ 0. These elements can be represented as a point on the worksheet.

After entering these basic elements for the motion tasks and determining the required boundary values, the connections can be entered according to the motion rules. Depending on the connection type used, a jerk-free motion can be achieved.

Introduction

Scaled motion rules

4.2Scaled motion rules

Each segment i of the whole cam describes a part which is defined by the value range si0 = f(ji0) and si1 = f(ji1).

The corresponding functions are imaged internally to the scaled value range of 0...1.

The coefficients of the profiles, included in the property pages, also refer to this scaled value range.

The speeds and accelerations in the property page represent the real boundary value

with regard to the geometrical dimensions. Thus, the calculation is based on the rule v = ds / dj and a = d2s / dj2.

These geometrical values for speed and and acceleration are also used in the graphical representation.

User interface

Language selection

5.2Language selection

You can always select another language for the menu, dialog and help texts of the »Cam Designer Basic«.

The available languages depend on the language files that have been installed together with the »Cam Designer Basic«.

How to select another language...

1.Select command View Set language.

2.Go to the Language configuration dialog box and select the desired language.

3.Click OK to confirm your selection and close the dialog box.

5.3Title bar

The title bar at the top of the application window shows the program icon and the program name on the left and the window icons on the right.

With a click on the Window icons			you can change the representation of the
application window as follows:
–	Icon in the task bar ( )
–	Full screen (	)
– Window size (		)

A click on the program icon opens the system menu which also includes commands for positioning and changing the size of the application window.

A click on the window icon or a double-click on the program icon exits the »Cam Designer Basic«

5.4Menu bar

Via this menu bar you have access to all menu commands of the »Cam Designer Basic«. In contrast to the »Cam Designer Professional« the profile functions are reduced.

A click on an item of the main menu opens the corresponding menu and lists the menu items contained in it.

Click a menu item to execute the corresponding function.

–Menu items which are displayed in light grey are currently deactivated because the execution of the corresponding function would not make any sense in the current program state.
