Epsilon EP-P Drive and FM-3/4 Module Reference Manual

A comment is automatically inserted after the index instruction, which shows key data about the specific index. Notice

comments start with the ‘ apostrophe character.

A “Wait For Index.AnyCommandComplete” instruction is automatically inserted after each Index.Initiate. This ensures that

the index has completed before the program continues on to the next line of code.

Once all of the program instructions have been inserted, your program window may look like Figure 110.

Now the program is complete, and is ready to be run. In order to run the program, the drive must be enabled and the setup

parameters must be downloaded. Once the download is complete, verify the drive is enabled and initiate your program.

Example Application Start Up

Figure 111: Example System

In order to make the setup easier to understand in this guide, the guide will use an example setup. The example application

used in the quick start guide is a ball screw application (see the drawing above).

The example uses these functions:

3 Indexes (Initiated through Assignments or through a Program)

2 Jogs

1 Home (to Sensor)

1 Program

Software Travel Limits

Following Error Limit

Several Setup Views do not require any setup for this example application, and therefore have been skipped. After opening

a new Configuration Window and inputting information on the Setup view and Motor view, move to the User Units view.

User Units View

This example requires use of distance units “Inches” versus the default units “revs”. The example has a linear device that

moves 1.00 Inch per 4 motor Revolution. The parameters you must fill out are as follows:

Units Name – Enter the character string you wish to name the distance units, such as “Inches” for this example.

Decimal Places – Enter the number of digits after the decimal place you wish to use in all distance parameters throughout

the software (i.e. index distances/positions). The example selects three digits allowing resolution of 0.001 Inches on all

distance variables. Use the Up/down arrows to set.

Distance Units Scaling – Enter the number of User Units the motor/load travels for each revolution of the motor. You must

enter the numerator and the denominator for this scaling factor, but for this example, the denominator (bottom portion of the

ratio) is at 4.

Position View

The example wishes to limit the Following Error to 0.25 Inches or one motor revolution, and the Software Travel Limits of

+20 and 0 Inches.

To setup following error limit and software travel limits, fill out the following parameters in the Limits Group:

0 20
