WARNING: 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.

WARNING: 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).

WARNING: 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.

	Preparing for an Installation	17
	Setting the Endianness and Node Address Switches	17
	Connecting the Option Module to the PowerFlex 750-Series	19
	Product
	Connecting the Option Module to the Network	20
	Network Termination	22
	Applying Power	22

Preparing for an Installation Before installing the option module, do the following:

•Read the PROFIBUS Installation Guideline for details on PROFIBUS networks.

•Verify that you have all required equipment.

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 8000- 4.5.2.

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:

•CTRL: Logic Command Word (4 bytes)

•REF: Speed Reference (4 bytes)

•STAT: Logic Status Word (4 bytes)

•FEEDBACK: Speed Feedback (4 bytes)

•0…16 Datalinks (4 bytes each)

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

IMPORTANT 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.

Set the Node Address by setting Node Address switches 1...7 to their binary equivalent, where '0' and '1' indicate switch positions 'Open' and 'Closed' respectively. Table 1 lists node addresses and the corresponding Node Address switch settings required to set that respective address.

Connecting the Option Module to the PowerFlex 750-Series Product

Chapter 2 Installing the Option Module

Descriptions of node address values are as follows.

Node Address Value	Description
00	If the Node Address value is set to ‘00’, the option module uses Device Parameter
	05 [Net Addr Cfg] to set the Node Address. See Setting the Node Address on
	page 30.
01…125	Node address used by the option module.
126	The default address setting.

The switch settings can be verified by viewing Device Parameter 06 [Net Addr Act], a read-only parameter, with any of the following drive configuration tools:

•PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM

•Connected Components Workbench software

IMPORTANT Remove power from the product before installing the option module in the 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 PowerFlex 750-Series product, 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 help 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 help 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.

Chapter 2 Installing the Option Module

Connecting the Option Module to the Network

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

1.Remove power from the PowerFlex 750-Series product.

2.Remove the product cover and lift up the drive HIM bezel to its open position to access the drive control pod.

3.Use static control precautions.

4.Route the PROFIBUS cable through the bottom of the PowerFlex drive.

5.Connect a PROFIBUS connector to the cable.

PROFIBUS connectors are available from a variety of sources and in various sizes. As such, there may be mechanical limitations that prohibit the use of some connectors. Phoenix SUBCON-PLUS-PROFIB/AX/SC (Part # 2744380), Siemens 6GK1500-0FC00, or Brad BM5G60PP4Mxxx are recommended for use with PowerFlex 750-Series drives.

Figure 2 - PROFIBUS Connector

6.Connect the PROFIBUS cable to the option module and secure it with the two screws on the connector.

IMPORTANT PROFIBUS communication may not operate correctly if the cable shield does not make full contact with the connector housing.

Chapter 2 Installing the Option Module

Network Termination

Applying Power

The first and last node on a PROFIBUS DP Network segment should be terminated.

Rockwell Automation recommends that you select one of the previously mentioned PROFIBUS connectors with built-in termination.

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 PowerFlex 750-Series product. The option module receives its power from the product. 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 7, Troubleshooting.

Startup Status Indications

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