Setting Up Parameters
Figure 55: Setup NVM View
FM Only
NVM Warning: Assigning parameters to NVM could shorten the life of your FM-3 or FM-4!
The Non-Volatile memory list displays the parameters that will be saved so they can be restored after a powerdown. A
command to store these parameters into the NVM is given to the module whenever a parameter on the list changes value
(via a program or a communications network). Currently the NVM in the FM-3/4 is rated at a minimum, 1 million writes.
Therefore, do not add parameters to the NVM list if these parameters will be changing more than an average of 1 time
every 30 seconds.
Capture View
Many applications require the ability to accurately capture a position at an exact moment in time so that the motion profile
can be repeatably time accurate. The FM-3/4 module and Epsilon EP-P drive allows for this by using the Capture component.
The Capture component is fully controlled by the user through the Assignments View or through the Programs View. When
the capture is activated, the following parameters are captured and stored: Time, Command Position, Feedback Position, and
Master Feedback Position.
