3.27.3 Assignment Polarity
The active state of an assignment can be programmed to be Active Off, Active On, or Custom using PowerTools Pro. Making
an assignment “Active On” means that the destination will be active when the source it is assigned to becomes active, and is
inactive when the source is inactive. Making an assignment “Active Off” means that the destination will be active when the
source it is assigned to is inactive, and will be inactive when the source is active.
The polarity of the assignment can also be changed to Custom when required. Custom polarity allows you to make a
destination activate and deactivate based on two different sources.
Destination functions which initiate motion (Jog.PlusInitiate, Jog.MinusInitiate, Index.#.Initiate, and Home.#.Initiate) cannot
be set “Active Off”.
Default polarity for a new assignment is Active On. Two methods will change the polarity of an assignment.
Polarity Button Method
Click on either the Source or the Destination you wish to change the polarity of. Once highlighted, the Polarity button will
become available in the lower right corner of the view. Click on the Polarity button and change the settings as desired in the
Polarity dialog box. Click OK to apply the changes.
Right Click Method
Position the pointer over the specific assignment you with to change polarity of and click the right mouse button. A selection
box will appear. From this selection box, choose Polarity. the Polarity dialog box will appear. Change the Polarity settings as
desired and click OK to apply the changes.
3.27.4 User Level
The User Level filters the available assignments. The User Level is changed on the Options menu at the top of the PowerTools
Pro toolbar. Choose Options/Preferences/User Levels. Easy mode filters out all but the most commonly used sources and
destinations. Detailed mode filters out less, expanding the list of sources and destinations for more complex configurations.
Too Much mode does not filter at all and provides all sources and destinations.
3.27.5 Only Show Assigned Check Box
When this check box is selected it removes the unassigned sources and destinations from the view. It allows the user to
quickly see how many sources and destinations have been assigned.
3.27.6 Assignments that Automatically Use Position Capture
Certain assignments (Sources or Destinations) automatically generate position capture data internally for greater performance
and accuracy. This captured data is used by the Epsilon EP-P drive, but is not directly available to the user. Following is a list
of assignments that automatically generate or use captured data.
