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 8000-4.5.2

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], 34 - [Idle Flt Action], and 36 - [Msg 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 explicit messaging for drive control is disrupted. By default, these parameters fault the drive. You may configure 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).

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 Node Address Switches

Set the option module Node Address switches (Figure 1) by rotating the switches to the desired value for each digit.

Each node on the ControlNet network must have a unique address. Set the node address before power is applied because the option module uses the node address it detects when it first receives power. To change a node address, you must set the new value and then remove and reapply power to (or reset) the option module.

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 have its control come from a peripheral or terminal block with the Reference coming from the network. Or you could set the drive to have its control come from the network with the Reference coming from another peripheral or terminal block. Or you could set the drive to have both its control and Reference come from the network.

Rockwell Automation Publication 750COM-UM003B-EN-P - November 2012 21

Chapter 2 Installing the Option Module

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.

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 this 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 this 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 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).

Setting the Node Address

If your drive has an enhanced PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM, it can be used to access parameters in the option module.

1. Display the Status screen, which is shown on HIM power up.

2. Use the or key to scroll to the Port in which the option

module is installed.

3. Press the PAR# soft key to display the Jump to Param # entry pop-up box.

4. Use the numeric keys to enter the desired parameter number, or use the 

or  soft key to scroll to the desired parameter number.

For details on viewing and editing parameters, see the PowerFlex 20-HIM-A6/C6S HIM (Human Interface Module) User Manual, publication 20HIM-

UM001.

When the option module Node Address switches (Figure 1) are set to ‘00’ (Program) the value of Device Parameter 05 - [Net Addr Cfg] determines the node address. When the Node Address switches are in any other combination of positions, these switches determine the node address.

Setting a Master-Slave Hierarchy (Optional)

1. Set the value of Device Parameter 05 - [Net Addr Cfg] to a unique node address.

2. Reset the option module; see Resetting the Option Module

This procedure is only required if Datalinks are used to write or read data of the drive or its connected peripherals. A hierarchy determines the type of device with which the option module exchanges data. In a Master-Slave hierarchy, the option module exchanges data with a master, such as a bridge or scanner (1756-CNB, 1756-CNBR, 1747-SCNR, and so forth).

Enable Datalinks To Write Data

on page 31.

The controller output image (controller outputs-to-drive) can have 0 to 16 additional 32-bit parameters (Datalinks). The Datalinks are configured using

Host Parameters 01 - [DL From Net 01] through Parameter 16 - [DL From Net 16]. The number of Datalinks actively used is controlled by the connection

size in the controller. See the respective controller example sections in Chapter 4 for more information on setting the connection size.

26 Rockwell Automation Publication 750COM-UM003B-EN-P - November 2012

IMPORTANT

TIP

Configuring the Option Module Chapter 3

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Host Parameters 01, 02, and 03 to configure three Datalinks to write data. Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

When using a ControlLogix controller and an RSLogix 5000 drive Add-On Profile (version 16 or later), there is no need to configure Datalink parameters at this time. They will be assigned when configuring the RSLogix 5000 drive Add-On Profile (see Add the Drive/Option Module to the I/O Configuration

page 39).

When using a ControlLogix controller and the Generic Profile—or a PLC-5 or SLC 500 controller, configure the Datalink parameters now as described in this section.

Host Parameters 01 - [DL From Net 01] through 16 - [DL From Net 16] configure which parameters in the drive, option module, or any other connected peripheral receive the values from the network. You can use the PowerFlex 20HIM-A6 or 20-HIM-C6S HIM, or another drive configuration tool such as Connected Components Workbench, DriveExplorer, or DriveExecutive software to select the drive or peripheral by port number and the parameter by name. As an alternate method, the parameter value can be set manually by number using this formula:

From Net Parameter Value = (10000 * port number) + (Destination Parameter Number)

For example, suppose you want to use Host Parameter 01 - [DL From Net 01] to write to Parameter 03 of an optional encoder module plugged into drive Port 5. Using the formula, the value for Host Parameter 01 - [DL From Net 01] would be (10000 * 5) + (3) = 50003.

Follow these steps to enable Datalinks to write data.

1. Set the values of only the required number of contiguous controller-todrive Datalinks needed to write data to the drive and that are to be included in the network I/O connection.

2. Reset the option module; see Resetting the Option Module

3. Since the Logic Command and Reference is always used in the option

module, configure the parameters in the drive to accept the Logic Command and Reference from the option module.

When using the controller for speed reference via the option module, set two fields in drive Parameter 545 - [Speed Ref A Sel].

a. Set the Port field for the drive (for example, 0 - PowerFlex 755). b. Set the Parameter field to point to the port in which the option module

is installed (for this example, Port 4 Reference). Also, verify that the mask parameters in the drive (for example,

Parameter 324 - [Logic Mask]) are configured to receive the desired logic from the option module. See the drive documentation for details.

Chapter 3 Configuring the Option Module

IMPORTANT

TIP

After the above steps are complete, the option module is ready to receive input data and transfer status data to the master (controller). Next, configure the controller to recognize and transmit I/O to the option module. See Chapter 4 Configuring the I/O.

Enable Datalinks To Read Data

The controller input image (drive-to-controller inputs) can have 0 to 16 additional 32-bit parameters (Datalinks). The Datalinks are configured using Host Parameters 17 - [DL To Net 01] through 32 - [DL To Net 16]. The number of Datalinks actively used is controlled by the connection size in the controller. See the respective controller example sections in Chapter 4 information on setting the connection size.

Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Host Parameters 17, 18, 19, 20, and 21 to configure five Datalinks to read data. Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

for more

When using a ControlLogix controller and an RSLogix 5000 drive Add-On Profile, version 16.00 or later, there is no need to configure Datalink parameters at this time. They will be assigned when configuring the RSLogix 5000 drive Add-On Profile (see Add the Drive/Option Module to the I/O

Configuration on page 39).

When using a ControlLogix controller and the Generic Profile—or a PLC-5 or SLC 500 controller, configure the Datalink parameters now as described in this section.

Host Parameters 17 - [DL To Net 01] through 32 - [DL To Net 16] configure which parameters in the drive, option module, or any other connected peripheral send the values to the network. You can use the PowerFlex 20-HIM-A6 or 20HIM-C6S HIM, or another drive configuration tool such as Connected Components Workbench, DriveExplorer, or DriveExecutive software to select the drive or peripheral by port number and the parameter by name. As an alternate method, the parameter value can be set manually by number using this formula:

To Net Parameter Value = (10000 * Port Number) + (Origination Parameter Number)

For example, suppose you want to use Host Parameter 17 - [DL To Net 01] to read Parameter 2 of an optional I/O module plugged into drive Port 6. Using the formula, the value for Host Parameter 17 - [DL To Net 01] would be (10000 * 6) + (2) = 60002.

Follow these steps to enable Datalinks to read data.

Setting a Fault Action

2. Reset the option module; see Resetting the Option Module

The option module is configured to send output data to the master (controller). You must now configure the controller to recognize and transmit I/O to the option module. See Chapter 4

By default, when communication is disrupted (for example, the network cable is disconnected), the controller is idle (in program mode or faulted) or explicit messaging for drive control is disrupted, the drive responds by faulting if it is using I/O from the network. You can configure a different response to these faults:

• Disrupted I/O communication by using Host Parameter 33 - [Comm Flt Action].

• An idle controller by using Host Parameter 34 - [Idle Flt Action].

• Disrupted explicit messaging for drive control via PCCC, the CIP Register Object, or the CIP Assembly object by using Host Parameter 36 - [Msg Flt Action].

ATTENTION: Risk of injury or equipment damage exists. Host Parameters 33 [Comm Flt Action], 34 - [Idle Flt Action], and 36 - [Msg Flt Action] let you

determine the action of the option module and connected drive if communication is disrupted, the controller is idle, or explicit messaging for drive control is disrupted. By default, these parameters fault the drive. You may configure 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 network cable, controller in idle state or explicit message control disruption).
