rollover range.
Example 2: If the starting position is at 90° and 80° is the specified position, an Absolute index would travel 10° in the negative direction. At
the completion of this index the motor position would be 80°.
Example 3: If the starting position is 45° and 315° is the specified position, an Absolute index would travel 90° in the negative direction
because that is the shortest path between 45° and 315°.
Rotary Plus indexes will move to the specified position and are forced in a positive (or plus) direction. Rotary Plus index distances must be
within the rotary rollover range.
Example 4: As in example 2 above, the starting position is at 90° and 80° is the specified position. A Rotary Plus index would travel 350° in
the positive direction. At the completion of this index the motor position would be 80°.
Example 5: If the starting position is 10° and the specified position is 350°, a Rotary Plus index will travel 340° in the positive direction.
Rotary Minus indexes move to the specified position, but are forced to travel in the negative (or minus) direction. Rotary Minus index positions
must be within the rotary rollover range.
Example 6: As in examples 2 and 4 above, the starting position is at 90° and 80° is the specified position. A Rotary Minus index would travel
10° in the negative direction. At the completion of this index the motor position would be 80°.
Example 7: If the starting position is 15° and the specified position is 270°, a Rotary Minus index would travel 105° in the negative direction.

How Communications Work

2.7.1

Configuring Communication

Before attempting to upload or download a configuration file using PowerTool Pro, the software must be configured to the correct
communication settings for the intended communication connection. The Epsilon EP-P drive supports both RS-485 serial communication
connections (J2) and Ethernet communication (J4) connection, on the front of the drive.
When downloading or uploading a selected configuration file that is open in PowerTools the communication scanner will only scan the
configuration file's Modbus ID and Ethernet address (unless Ethernet change address is clear). Once a connection is established, that
connection (Comm port used, port number, modbus ID and Ethernet address) is saved, a second download, upload or reconnect will bypass
the scanner and use this previously defined communication path. To change the communication path use the Change Path toolbar button.
The communication connection may be selected in the Upload Drive Configuration, Download to Device IDx or the Change Path dialog boxes.
From the Device menu, choose Upload Drive, Download or Path Change to open the dialog box or the toolbar buttons can also be used,
see below.
2.7.2

Upload Drive

Uploading is the process of reading information back from the drive to the PowerTools Pro configuration file views.
To upload information from a drive, click on the Upload All button, on the PowerTools Pro toolbar or from the Device menu,
choose Upload All or Upload Drive. The Upload Drive Configuration dialog box will open, all communication connections are
scanned and the results appear. In Figure 27, it shows that one drive on COM 1 was found, an Epsilon EP204-P drive. The Upload
Drive Configuration dialog box contains the following information for every drive found:
