Installation Instructions

Stegmann Feedback Option Board for PowerFlex

700S Drives

ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged completely before servicing. Check the DC bus voltage at the Power Terminal Block by measuring between the +DC and -DC terminals, between the +DC terminal and the chassis, and between the -DC terminal and the chassis. The voltage must be zero for all three measurements.

ATTENTION: HOT surfaces can cause severe burns. Do not touch the heatsink surface during operation of the drive. After disconnecting power allow time for cooling.

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.

What This Kit Contains

Tools That You Need

ATTENTION: The sheet metal cover and mounting screws on the ASIC Board located on the power structure are energized at

(-) DC bus potential high voltage. Risk of electrical shock, injury, or death exists if someone comes in contact with the assembly.

Verify that your kit contains the items listed in the following table. If your kit does not contain the correct items, contact your Rockwell Automation sales representative.

What You Need to Do

To remove the Stegmann Feedback option board from the PowerFlex 700S drive:

❐Step 1: Remove power from drive ❐Step 2: Remove cover(s) from drive ❐Step 3: Remove control assembly from drive ❐Step 4: Remove feedback option board

To install the new Stegmann Feedback option board on the PowerFlex 700S drive:

❐Step 5: Install feedback option board ❐Step 6: Install Phase I control assembly ❐Step 7: Wire Stegmann feedback option board to encoder ❐Step 8: Install Phase II control assembly ❐Step 9: Install covers on drive ❐Step 10: Document change

To return a replaced Stegmann Feedback option board to Rockwell Automation, use the packing material from the new Stegmann Feedback option board.

Step 1: Remove Power from the Drive

Stegmann Feedback Option Board for PowerFlex® 700S Drives 3

ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before performing

any work on the drive. Measure the DC bus voltage at the DC+ & DC- terminals of the Power Terminal Block. The voltage must be zero.

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.

1. Turn off and lock out input power. Wait five minutes.

2. Verify that there is no voltage at the drive’s input power terminals.

3. Measure the DC bus voltage at the DC+ & DC- terminals on the Power

Terminal Block. The voltage must be zero.

Frame 1 - 6 Size Drives with Phase II Control

Frame Action 1 - 4 Locate the slot in the upper left corner (as shown below). Slide the locking tab up and swing

the cover open. Special hinges allow the cover to move away from drive and lay on top of an adjacent drive (if present).

5 Slide the locking tab up, loosen the right-hand cover screw and remove the cover. 6 Loosen the two screws at bottom of the drive cover. Carefully slide the bottom cover down

and out. Loosen the two screws at top of cover and remove the cover.

Step 3: Remove the Control Assembly from the Drive

The steps to remove the control assembly from the drive are different for drives with Phase I control versus drives with Phase II control. Refer to the appropriate instructions:

• Refer to Drives with Phase I Control

• Refer to Drives with Phase II Control

below.

on page 7.

Drives with Phase I Control

This step is necessary only when another drive or panel component blocks access to the control assembly on frame 1 - 6 drives with Phase I control. Avoid removing the control assembly if possible. If you do not need to remove the control assembly from the drive, continue with Step 4: Remove

the Feedback Option Board on page 9.

Important:Before removing connections and wires, mark the connections

and wires to avoid incorrect wiring during assembly.

Task Description

Unplug the I/O and SynchLink cables from the main control board, unplug feedback wiring

from the MDI Option board (if present), and unplug the communication cables from DriveLogix controller (if present).

Unplug the ribbon cable.

Remove the three M5 nuts that secure the control assembly to the drive chassis.

Remove the control assembly from the drive.

Continue with Step 4: Remove the Feedback Option Board
