Chapter 6 Axis Configuration Examples for the PowerFlex 755 Drive
Example 3: Velocity Loop
with Motor Feedback Via a
UFB Feedback Device
This example describes how to create two AXIS_CIP_DRIVE axes that are
associated to a PowerFlex 755 drive with dual motor feedback via a universal
feedback device, catalog number 20-750-UFB-1.
1. Once you have created an AXIS_CIP_DRIVE, open the Axis Properties.
2. Connect the Feedback Port 1 with one feedback cable that is connected to
the PowerFlex 755 drive.
3. From the Axis Configuration pull-down menu, choose Velocity Loop.
4. From the Feedback Configuration pull-down menu, choose Motor
Feedback.
Example 3: Velocity Loop with Motor Feedback, General Dialog Box
Now that you defined the axis as a Velocity Loop with Motor Feedback,
the Motor and Motor Feedback dialog boxes become available.
TIP
Remember that you already assigned the feedback device when you
added the drive to your project.
This shows you the type of drive you selected
and power structure you assigned via the
PowerFlex 755 drive Module Properties.
See Add a PowerFlex 755 Drive on page 49
.
The newly created PowerFlex 755 drive module
name is the default. The Axis Number defaults to
1, indicating the primary axis of the drive. Axis
Number 2 is used only for configuring a Feedback
Only axis.
The selections determine the Control Mode.

IMPORTANT
After you have configured the axis and you change the Axis Configuration type
or the Axis Number, some of the configuration information is set to default
values. This can cause some previously entered data to be reset back to its
default setting.
