Motor Data Files for Exlar Actuators and Emerson/Control Techniques Drives (motor.ddf files)

Update July 11, 2005 (changes shown in bold type)

Data for Exlar actuators using Epsilon EP drives can be found in the linked files below. The Epsilon EP amplifiers from Control Techniques require actuators configured with the "M" selection for connectors, and the "EM2" call-out for feedback. The proper feedback cable for this combination from CT is the UFCS-xxx. Due to the differences in wiring and motor file parameters between the different CT amplifiers and cables, please contact Exlar application engineers for assistance if you are trying to use any other combination.

If you do not find the motor data file for your application, please contact Exlar.

Once you have located the motor data file for your actuator, there are two ways to convey that information into PowerTools Pro or PowerToolsFM.

The first is to change the name of the existing motor.ddf file in the PowerTools to oldmotor.ddf. This way you won’t discard any motor data you may have added. Then change the name of the file you need to work with from the list above to motor.ddf and copy into the folder where PowerTools resides. When PowerTools (Pro or FM) starts, the program will load that data into the motor selection area.

If you need to keep your existing motor.ddf data file, you will need to copy the motor data for your actuator into the motor.ddf file. Open the text file that contains the information for your actuator with a plain text editor such as Notepad. Locate the data for your actuator by finding the appropriate motor name. (See the selection charts on the www.exlar.com website engineering reference for the correct name.)

The data for a sample motor would look like the following:

If the data you need to enter falls outside the above limits:

1) if below the minimum value, enter the minimum value from above, e.g., the phase resistance for your motor is 0.04 ohms, enter phaseresistance=0.1 ohms.

2) if above the maximum value, enter the maximum value from above, e.g., the phase inductance for your motor is 122.76 mH, enter phaseinductance=99.99 mH.

Highlight all of the data in that paragraph and copy that selection to the Clipboard. Open your motor.ddf file. Move your cursor to the very end of the file. Paste your motor data from the Clipboard into that position.

Change the motor number in the brackets [motor1] to a number that is one greater than the last entry. Then change the nameCount at the start of the file to the existing total plus 1.

Now save this file as a plain text file named motor.ddf. If your word processing or text editor didn’t save the file as motor.ddf, close the word processor or text editor. Using Windows Explorer, locate the file you just created (probably shown as motor.ddf.txt or motor.ddf.doc). Highlight the filename and click the right mouse button. Select the RENAME option. When the cursor appears in the file name area, change the filename to “motor.ddf”. Finalize the change by hitting the Enter key.

Now (one last step), copy the motor.ddf file to the same folder that contains the PowerTools FM or PowerTools Pro program you will be using. Start the PowerTools Program. Open a new file. Under Setup select a new motor. The motor you selected in the previous steps should appear as the last selection (you may have to arrow down to get to it). Select your motor and continue with the PowerTools setup.

If you experience any difficulty or don’t find the motor you are looking for, give us a call at Exlar at 952-368-3434 and ask for applications assistance.
