Installation Instructions
PowerFlex® DC Drive Resolver Feedback Option Module
ATTENTION: Only qualified personnel familiar with DC drives and
associated machinery should plan or implement the installation, start-up
and subsequent maintenance of the system. Failure to comply may result in
personal injury and/or equipment damage.
ATTENTION: To avoid an electric shock hazard, ensure that all power to
the drive has been removed before performing the following.
ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive
parts and assemblies. Static control precautions are required when
installing, testing, servicing or repairing this assembly. Component damage
may result if ESD control procedures are not followed. If you are not
familiar with static control procedures, reference A-B publication 8000-
4.5.2, “Guarding Against Electrostatic Damage” or any other applicable
ESD protection handbook.

PowerFlex® DC Drive Resolver Feedback Option Module
What You Need to Do
Step 1: Remove Power
from the Drive
To install the resolver feedback option module:
❐ Step 1: Remove power from the drive
❐ Step 2: Open the drive
❐ Step 3: Install the resolver interface board
❐ Step 4: Install the resolver feedback board
❐ Step 5: Wire the resolver interface and feedback boards
❐ Step 6: Replace the protective covers and configure the resolver feedback
option module
ATTENTION: Remove power before making or breaking cable
connections. When you remove or insert a cable connector with power
applied, an electrical arc may occur. An electrical arc can cause personal
injury or property damage by:
• sending an erroneous signal to your system’s field devices, causing
unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance.
• Remove and lock-out all incoming power to the drive.

Frame A Drives
1. Disconnect the DPI cable from the HIM (if installed).
2. Loosen the captive screws that secure the bottom front cover to the drive,
then slide the cover down and off the drive chassis.

3. Press in on the sides at the bottom edge of the cover and at the same time
pull the cover toward you to pull it partially off the drive chassis. Next, at
the top of the drive, pull the cover forward, away from the drive, until the
pins fit in the keyhole in the top of the cover, then carefully lift the cover
off of the drive chassis.
IMPORTANT
Continue with Disconnect the HIM Communication Cable

The HIM assembly is connected via a cable to the control
board and therefore will not pull free from the drive until
disconnected.

Frame D Drives
1. Disconnect the DPI cable from the HIM assembly (if installed) (see
Figure 1 on page 5
2. Loosen, but do not remove, the four hexalobular screws that secure each of
the three covers to the control pan on the drive, then slide the covers up
and off the drive chassis (see Figure 1 on page 5
noted in the illustration for reassembly.
IMPORTANT
Continue with Disconnect the HIM Communication Cable

).
A communication cable connects the HIM assembly to the
control board mounted on the control pan. Therefore, the
middle control pan cover and HIM assembly cannot be fully
removed from the drive until the cable is disconnected.
