Step 1: Gather Required Information

When you apply power to your drive for the first time, you need to enter specific information about your application. You

need to enter motor nameplate data and set up your I/O.

Step 1: Gather Required Information helps you to verify that you have the needed information prior to drive powerup.

Record Motor Nameplate Data

Record the motor nameplate data to be entered into the Motor Data parameters during powerup. You can also record data

for up to five drive/motor combinations. Use this table to record a descriptive name for each drive/motor combination and

their respective parameters.

(1) Use the Slip RPM rather than the Synchronous RPM.

Example: Use 1750 RPM rather than 1800 RPM for a 60 Hz motor.

Motor NP RPM

29 (2)

(2) The default units for parameter 29 [Motor NP Pwr Units] is horsepower (Hp).

Mtr NP Pwr Units ❑kW ❑Hp ❑kW ❑Hp ❑kW ❑Hp ❑kW ❑Hp ❑kW ❑Hp

30 Motor NP Power

31 (3)

(3) To calculate: Number of poles = 120 x parameter 27 [Motor NP Hertz] / parameter 28 [Motor NP RPM]. Round the result to the nearest even whole number.

Example: 120 x 60 Hz / 1800 RPM = 4 poles

Motor Poles

Step 2: Validate the Drive Installation

It is important that you thoroughly inspect each of your drive installations before applying power for the first time. This is

especially important if you did not personally perform the installation tasks. Satisfy yourself now that each drive is ready to

be energized when you get to Step 3: Power Up, Configure the Drive, and Spin the Motor Shaft.

Identify Which Drive You Have

There are two types of PowerFlex 750-Series drives, the PowerFlex 753 and the PowerFlex 755. There are some important

differences between the drives that need to be considered in subsequent steps. If you don’t know how to determine what

type of drive you have, see Determine Drive Type on page 22.

Verify Power Wiring

Visually inspect the power wiring connections to each drive. Be sure you are satisfied that the correct wires are connected to

the input terminals and to the output terminals. See Power Wiring on page 23 for more information on where these

connections are made.

ATTENTION: To avoid an electric shock hazard, the drive must be locked and tagged before continuing Step 2: Validate the Drive

Installation. Failure to comply can result in personal injury and/or equipment damage.

Proper ground wire terminations at PE ground studs. ❑❑❑❑❑

If equipped, dynamic brake resistor connection is on BR1 and BR2.

If wires are present, go to Dynamic Brake Resistor on page 66 to record

dynamic brake resistor nameplate information.

❑❑❑❑❑

IMPORTANT

Rockwell Automation recommends that XLPE-type cabling be used on output of the drive.

Rockwell Automation Publication 750-QS001A-EN-P - March 2015 9

Step 2: Validate the Drive Installation

Verify Power Jumper Configuration

PowerFlex 750-Series drives contain protective MOVs and common mode capacitors that are referenced to ground. To

guard against drive damage and/or operation problems, these devices must be properly configured.

Record that the power jumper configuration for each drive is correct.

Verify I/O Wiring

To properly configure a drive, you need to know the source of the speed reference and the start/stop commands. There are

three places where signal sources (such as push buttons and potentiometers) are connected to the drive.

1. The drive’s main control board.

• Terminal block TB1 on a PowerFlex 753

• Embedded EtherNet/IP port on a PowerFlex 755

• Terminal block TB1 on a PowerFlex 755 Di0

2. An expansion I/O module.

3. A communication network module.

IMPORTANT

A properly configured drive has all jumpers connected or all jumpers disconnected, depending on whether the power source is

solid grounded or non-solid grounded. If jumpers are not all connected or all disconnected, the power jumpers are not properly

configured. The drive power source type must be accurately determined and the jumpers must be configured for the power source.

See Power Jumpers on page 27 for more information on common power source types and where power jumpers are in the drive.

IMPORTANT

The drive can always be controlled by the HIM for speed, start, and stop control. If that is the case for operating conditions, proceed

to Step 3: Power Up, Configure the Drive, and Spin the Motor Shaft on page 12.

Step 2: Validate the Drive Installation

Where are Signal Sources Connected?

Use this diagram to help determine where signal sources are connected in each of your drives.

You will need this information when you get to Step 4: Set Up Speed Reference and Start/Stop on page 17.

IMPORTANT

The 750-Series drive uses the term ‘Port’ to designate (in software) the physical location where hardware is located for ease of

selecting hardware or functions to program. For more information on port locations, see Drive Device Ports on page 33.
