3-4 Placing and Configuring the Drive
You must configure the Requested Packet Interval (RPI) rate for the drive.
This setting affects how fast the controller reads and writes the data in the
drive interface.
The Drive consumes data from the DriveLogix controller every 2 milliseconds,
and produces data to the controller every 2 milliseconds. The drive updates the
inputs and outputs to the controller asynchronous to both the program scan
and I/O scan of the controller.
Placing and Configuring the
Drive When you create a project for the DriveLogix controller in RSLogix 5000, the
Controller Organizer automatically displays the local DIN rail for Flex I/O.
You must add the PowerFlex 700S drive to the configuration, in a manner
similar to adding an I/O module. The Controller Organizer automatically
places the drive in slot two.
TIP
If you want data to remain constant throughout one scan,
make a copy of the data at the beginning of the scan and
use the copy throughout the scan.
1. In the Controller Organizer, select the I/O Configuration folder. Right-click the selected
folder and select New Module..
2. Select the drive (PowerFlex 700S-400V
in this example).
