Introduction

Using an IM 178-4 as an example of a distance measurement and output module,

this primer leads you through six commissioning steps to a working application. It

allows you to familiarize yourself with the basic functions of Easy Motion Control.

Depending on your experience, it will take between one and two hours of your

time.

At the end of this primer, you will find information on

using other distance measurement and output modules as well as

testing in simulation mode without drive

Requirements

The following requirements must be fulfilled:

You must have configured and wired an S7 station consisting of a power

supply module, CPU with DP connection and a decentrally coupled IM 178-4

as well as your drive together with encoder.

For installation and wiring of the IM 178-4, see the "IM 178-4 Drive Interface"

manual.

Wiring includes connecting the enable input of your power unit to a digital

output of the IM 178-4 (see step 5.9 ).

STEP 7 (

V5.0 + Service Pack 3) is correctly installed on your programming

device.

Your programming device is connected to the CPU.

You have set up a project for your S7 station.

You are in possession of the Easy Motion Control software product.

You are familiar with the STEP 7 configuration package, particularly with the

SIMATIC Manager and the LAD/STL/FBD-Editor.

You have provided safety limit switches and EMERGENCY STOP switches to

safeguard the safety of operating staff and the system itself.

Warning

Injury may occur to persons and property.

Uncontrolled travel motions during commissioning and operation can cause

severe injury to persons and property.

To avoid injury to persons and objects, take the following precautions:

Install an EMERGENCY STOP switch in the vicinity of the computer. This is

the only way to ensure that the system is reliably switched off in the event of a

hardware or software failure.

Install safety limit switches with direct control over the power units of all drives.

Ensure that nobody has access to anywhere of the system where there are

moving parts.

Functionality of Example

You generate a user program allowing you to move your axis in jogging mode.

Step 1: Easy Motion Control Installation

Install the software by starting the installation program Setup.exe on the CD-ROM

and following its instructions.

More detailed information can be found in the Easy Motion Control manual under

"Installation of Easy Motion Control". The manual can be found in unzipped form on

the installation CD under Manuals\English\EasyMotionControl.pdf.

Step 2: Parameterization in HW Config

Parameterize the time interrupt of OB35 in the CPU with 10 ms (CPU 318 or S7-

400) or 20 ms (S7-300 to CPU 316).

In OB35, you later launch Easy Motion Control blocks in Step 5.

Select IM 178-4 from the module catalogue in HW Config under PROFIBUS-DP >

Function Modules > IM 178-4 . Configure slot 4 of the IM 178-4 as "4Word

AO/12Word AI/Cons. 1Word".

Parameterize the IM 178-4 as follows:

Step

Setting

2.1

Synchronization

Software

2.2

Edge selection

Rising or falling edge

Parameterize the other settings according to the connected encoder.

Step 3: Parameterization of Axis Data

Step

Job

Result

3.1

Open the Easy Motion Control configuration software

on your PC via the Windows start menu ( Start >

Simatic > STEP 7 > Easy Motion Control ).

The Easy Motion Control window

appears.

3.2

Select the menu function File > New from the configuration software.

3.3

In the "New" window, open the block container of your project.

3.4

Under "Object Name", enter a DB that does not yet

exist in your project, e.g. DB1. This DB is regenerated

with "OK".

UDT AXIS_REF is thereby copied from the library

"EMC Easy Motion Control" into the "Blocks" container

of your project.

Note : You should not then delete this UDT AXIS_REF

or change the UDT number.

The dialog is opened for

parameterizing the DB.

3.5

Enter all parameters corresponding to your axis. You will find an explanation of parameters

in the configuration software’s online help (F1 key).

In the "Commissioning" register, the configuration software offers help in determining

parameters.

• "Set encoder polarity"

• "Set drive polarity"

• "Axis distance per encoder revolution" and:

• "Max. axis velocity "

see step 4 .

3.6

Save the axis DB that has just been parameterized in

your offline database organization.

The DB is generated and

parameterized.
