Safety Precautions

Please read the following safety precautions carefully.

ATTENTION: Risk of injury or death exists. The PowerFlex drive may contain high voltages that can cause injury or death. Remove all power from the PowerFlex drive, and then verify power has been discharged before installing or removing the option module.

ATTENTION: Risk of injury or equipment damage exists. Only personnel familiar with drive and power products and the associated machinery should plan or implement the installation, startup, configuration, and subsequent maintenance of the drive using the option module. Failure to comply may result in injury and/or equipment damage.

ATTENTION: Risk of equipment damage exists. The option module contains electrostatic discharge (ESD) sensitive parts that can be damaged if you do not follow ESD control procedures. Static control precautions are required when handling the option module. If you are unfamiliar with static control procedures, see Guarding Against Electrostatic Damage, publication

ATTENTION: Risk of injury or equipment damage exists. If the option module is transmitting control I/O to the drive, the drive may fault when you reset the option module. Determine how your drive will respond before resetting the module.

ATTENTION: Risk of injury or equipment damage exists. Host Parameters 33 - [Comm Flt Action], and 34 - [Idle Flt Action] let you

determine the action of the option module and connected drive if I/O communication is disrupted, the controller is idle, or Acyclic messaging for drive control is disrupted. By default, these parameters fault the drive. You can set these parameters so that the drive continues to run, however, precautions should be taken to verify that the settings of these parameters do not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable or a controller in idle state).

8000-4.5.2.

ATTENTION: Risk of injury or equipment damage exists. When a system is configured for the first time, there may be unintended or incorrect machine motion. Disconnect the motor from the machine or process during initial system testing.

ATTENTION: Risk of injury or equipment damage exists. The examples in this publication are intended solely for purposes of example. There are many variables and requirements with any application. Rockwell Automation does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

Setting the Endianness and Node Address Switches

Set the Endianness of the option module with Byte Swap switch 8 (see Figure 1). The Byte Swap switch can be set to either open ‘0’ (Little Endian) or closed ‘1’ (Big Endian) data formats for the cyclic data exchanged on the network. The cyclic data consists of the following items:

Depending on the setting of the Byte Swap switch 8, the 4 bytes for each of the above data items are swapped.

• CTRL: Logic Command Word (4 bytes)

• REF: Speed Reference (4 bytes)

• STAT: Logic Status Word (4 bytes)

• FEEDBACK: Speed Feedback (4 bytes)

• 0 to 16 Datalinks (4 bytes each)

Set the Node Address by setting Node Address switches 1 through 7 to their binary equivalent, where '0' and '1' indicate switch positions 'Open' and 'Closed'

respectively. Ta b l e 1 switch settings required to set that respective address.

Each node on the Profibus network must have a unique address. Set the node address before power is applied because the option module detects the node address during initialization (Power On Reset). To change a node address, you must set the new value and then remove and reapply power to (or reset) the option module.

TIP

Connecting the Option Module to the Drive

Remove power from the drive before installing the option module in the drive control pod.

1. Insert the option module into Port 4, 5, or 6 and tighten the module mounting screws into the pod mounting bracket. To properly ground the module to the drive, torque both mounting screws to 0.45…0.67 N•m (4.0…6.0 lb•in).

2. When another module (I/O, encoder, communication, and so forth) resides in the adjacent port to the left of the 20-750-PBUS option module—and the lower mounting screw of that module is a larger T15 Torx head screw, perform addition steps 2a through 2d. If the port is empty or the adjacent module already uses the smaller T8 Torx head mounting screws, save this spare screw for future use.

The option module is shipped with a small bag containing a spare T8 Torx head mounting screw and an adhesive-backed polycarbonate insulator strip. The larger T15 Torx head mounting screw on the adjacent left module may electrically contact the metal Profibus cable connector when attached to the Profibus module. The polycarbonate insulator strip is provided to prevent electrical contact between the smaller T8 Torx head mounting screw and the Profibus cable metal connector when attached to the Profibus module. Either of these possible electrical contact situations may cause faulty operation. To prevent this, perform the following steps.

a. Remove the adjacent module’s lower mounting screw, the T15 Torx

head screw closest to the bottom of the pod mounting bracket.

To remove the captive T15 Torx head screw, the module must be removed to back the screw out of the mounting clip.

b. Replace the larger T15 Torx head screw with the smaller, spare T8 Torx

head mounting screw.

c. Tighten the mounting screw to the pod mounting bracket to properly

ground the adjacent module to the drive. Torque the screw to

0.45…0.67 N•m (4.0…6.0 lb•in).

d. Attach the adhesive-backed polycarbonate strip to the metal Profibus

cable connector in a location that prevents electrical contact between the connector and the adjacent module’s lower mounting screw when the connector is attached to the Profibus module.

Applying Power

ATTENTION: Risk of equipment damage, injury, or death exists.

Unpredictable operation may occur if you fail to verify that parameter settings are compatible with your application. Verify that settings are compatible with your application before applying power to the drive.

Apply power to the drive. The option module receives its power from the drive. When you apply power to the option module for the first time, its topmost PORT status indicator should be steady green or flashing green after initialization. If it is red, there is a problem. See Chapter

Start-Up Status Indications

The drive STS (status) indicator can be viewed on front of the drive after power has been applied. The option module status indicators can be viewed with the drive cover open or removed (Figure 5

Configuring and Verifying Key Drive Parameters

The PowerFlex 750-Series drive can be separately configured for the control and Reference functions in various combinations. For example, you could set the drive to receive control commands from a peripheral or terminal block, with the Reference coming from the network. You could also set the drive to receive its control from the network with the Reference coming from another peripheral or terminal block. Or you could set the drive to receive both its control and Reference from the network.

The following steps in this section assume that the drive will receive the Logic Command and Reference from the network.

1. Verify that drive parameter 301 - [Access Level] is set to ‘1’ (Advanced) or ‘2’ (Expert) to access the required parameters in this procedure.

2. Use drive Parameter 545 - [Speed Ref A Sel] to set the drive speed Reference source:

a. Set the Port field to ‘0’ as shown below.

b. Set the Parameter field to point to the port (slot) in which the option

module is installed (for example, Port 4 Reference). The number ‘874’ in the Parameter field of the example dialog box

above is the parameter in the drive that points to the port.

3. Verify that drive Parameter 930 - [Speed Ref Source] is reporting that the source of the Reference to the drive (Port 0) is the port in which the option module is installed (for example, Port 4 Reference).

This ensures that any Reference commanded from the network can be

monitored by using drive Parameter 002 - [Commanded SpdRef ]. If a

Chapter 2 Installing the Option Module

problem occurs, this verification step provides the diagnostic capability to determine whether the drive/option module or the network is the cause.

4. If hard-wired discrete digital inputs are not used to control the drive, verify that all unused digital input drive parameters are set to ‘0’ (Not Used).
