1-4 Getting Started

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

power from the PowerFlex drive, and then verify power has been discharged before installing or removing an adapter.

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, start up, configuration, and subsequent maintenance of the product using an adapter. Failure to comply may result in injury and/or equipment damage.

ATTENTION: Risk of equipment damage exists. The adapter contains ESD (Electrostatic Discharge) sensitive parts that can be

damaged if you do not follow ESD control procedures. Static control precautions are required when handling the adapter. If you are unfamiliar with static control procedures, refer to Guarding Against Electrostatic Damage, Publication 8000-4.5.2.

ATTENTION: Risk of injury or equipment damage exists. If the adapter is transmitting control I/O to the drive, the drive may fault when

you reset the adapter. Determine how your drive will respond before resetting an adapter.

ATTENTION: Risk of injury or equipment damage exists. Parameter 02 - [Comm Loss Action] lets you determine the action of

the adapter and connected PowerFlex drive if communications are disrupted. By default, this parameter faults the PowerFlex drive. You can set this parameter so that the drive continues to run. Precautions should be taken to ensure that the setting of this parameter does 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).

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.

Getting Started 1-5

ATTENTION: Risk of injury or equipment damage exists. Parameter 03 - [Comm Loss Time] lets you determine how long it will take the

adapter to detect network communication losses. By default, this parameter sets the timeout to ten seconds. You can set it so that the duration is shorter, longer, or disabled. When set to disabled, this also disables adapter Parameter 02 - [Comm Loss Action]. Therefore, a communications fault action will be ignored. Take precautions to ensure that the setting does 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).

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, Inc. does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

Configuring/Verifying Key Drive Parameters

The PowerFlex 7-Class 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 BACnet MS/TP network. Or you could set the drive to have its control come from the BACnet MS/TP 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 BACnet MS/TP network.

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

1. Using drive Parameter 090 - [Speed Ref A Sel], set the drive speed

Reference to “22” (DPI Port 5).

2. Verify that drive Parameter 213 - [Speed Ref Source] is reporting

that the source of the Reference to the drive is “22” (DPI Port 5). This ensures that any Reference commanded from the network can be monitored by using drive Parameter 002 - [Commanded Speed]. If a problem occurs, this verification step provides the diagnostic capability to determine whether the drive/adapter or the network is the cause.

Connecting the Drive/Adapter 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 removed before installing or removing an adapter.

1. Remove power from the drive.

2. Use static control precautions, and remove or open the drive cover.

3. Connect a shielded, twisted wire pair to the network, and route it

through the bottom of the drive (see Figure 2.6

4. Connect the twisted wire pair and its shield to the 3-pin linear plug

(provided with the adapter). See Figure 2.8 and typical terminal connections.

Setting the Device Instance Number

While there are many ways to implement Device Instance and network strategies, the example shown in Figure 3.1 illustrates one logical approach.

In this example, two individual Floor Level Networks are connected to the Building Level Network through a router which allows devices on each network to share the same MAC address. However, each device on the network must have a unique Device Instance which, in this case, consists of 4 digits. The first digit (in bold) represents the Building or Floor number. The last 3 digits represent the device’s set MAC address.

Configuring the Adapter 3-5

Setting a Comm Loss Action

By default, when communications are disrupted (for example, a cable is disconnected), the drive responds by faulting if it is using I/O from the network. You can configure a different response to communication disruptions using Parameter 02 - [Comm Loss Action].

ATTENTION: Risk of injury or equipment damage exists. Parameter 02 - [Comm Loss Action] lets you determine the action of

the adapter and connected drive if communications are disrupted. By default, this parameter faults the drive. You can set this parameter so that the drive continues to run. Take precautions to ensure that the setting of this parameter does 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).

To change the Comm Loss Action

Set the value of Parameter 02 - [Comm Loss Action] to the desired response action:

Value Action Description

0 Fault The drive is faulted and stopped. (Default)

1 Stop The drive is stopped, but not faulted.

2 Zero Data The drive is sent 0 for output data. This does not command a stop.

3 Hold Last The drive continues in its present state.

4 Send Flt Cfg The drive is sent the data that you set in the fault configuration

To set the fault configuration parameters

If you set Parameter 02 - [Comm Loss Action] to “Send Flt Cfg,” the values in the following parameters are sent to the drive after a communications fault occurs. You must set these parameters to values required by your application.

Parameter Name Description

05 Flt Cfg Ref A 32-bit value (0 – 4294967295) sent to the drive as a

Changes to these parameters take effect immediately. A reset is not required.

Setting the Comm Loss Time

Set Parameter 03 - [Comm Loss Time] to a communication loss timeout period suitable for your application. By default, the timeout is set to ten (10) seconds. You can increase or decrease this value. Alternatively, you can set the value to zero (0) to disable this timeout feature so that the adapter does not detect communication losses.

Reference.

Important: If the drive uses a 16-bit Reference, the most significant word of the value must be set to zero (0) or a fault will occur.

ATTENTION: Risk of injury or equipment damage exists. Parameter 03 - [Comm Loss Time] lets you determine how long it will take the

adapter to detect network communication losses. By default, this parameter sets the timeout to ten (10) seconds. You can set it so that the duration is shorter, longer, or disabled. When set to disabled, this also disables adapter Parameter 02 - [Comm Loss Action]. Therefore, a communications fault action will be ignored. Take precautions to ensure that the setting does 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).

Setting the Baud Rate

The value of Parameter 06 - [Baud Rate Cfg] determines the baud rate used by the adapter. The Autobaud setting will detect the baud rate used on the network if another device is setting the baud rate. Your application may require a different setting.

1. Set the value of Parameter 06 - [Baud Rate Cfg] to the baud rate at

which your network is operating.

Resetting the Adapter

Changes to switch settings or some adapter parameters require that you reset the adapter before the new settings take effect. You can reset the adapter by cycling power to the drive or by using Parameter 01 - [Reset

Module].

ATTENTION: Risk of injury or equipment damage exists. If the

adapter is transmitting control I/O to the drive, the drive may fault when

you reset the adapter. Determine how your drive will respond before resetting a connected adapter.

Set Parameter 01 - [Reset Module] to Reset Module.

Chapter 4 provides information about controlling a compatible PowerFlex 7-Class drive using BACnet objects.

Topic Page

Understanding BACnet Objects

Basic Drive Operation on the Network 4-2

Supported BACnet Objects 4-3

Understanding BACnet Objects

BACnet nodes are controlled and monitored by the use of several types of objects. The BACnet controller performs read and write commands to these objects, and the adapter transfers/translates the data between these objects and the drive.

When a read or write command occurs to a specific object, data in the object is refreshed from or transferred to the drive.

4-1

The BACnet object types that are supported by the adapter are:

• Analog Input (AI)

• Analog Output (AO)

• Analog Value (AV)

• Binary Input (BI)

• Binary Output (BO)

• Binary Value (BV)

4-2 Using BACnet Objects

Basic Drive Operation on the Network

This section describes how to operate a drive on the network using a combination of BACnet object types for basic control.

ATTENTION: Control information written to the adapter by a BACnet controller is volatile. That is, it will not survive an adapter reset or

power cycle. For example, if a BACnet controller writes to a Binary Output (BO) object to energize an output relay on the drive and then that drive is reset or power cycled, the drive will return the relay to its default (de-energized) state. The adapter will not attempt to restore the relay to the energized state unless a BACnet controller writes to it again.

Basic Drive Control (Start/Stop)

1. Write a speed reference value (in %) to the Reference 1 Analog

Value object (AV0) Present Value property.

2. To start the drive, write a value of “1” to the Run/Stop Binary Value

object (BV10) Present Value property.

3. To stop the drive, write a value of “0” (zero) to the Run/Stop Binary

Value object (BV10) Present Value property.

Using an Alternate Speed Reference

To assign an alternate speed reference to the drive:

1. Write a speed reference value (in %) to the Reference 2 Analog

Value object (AV1) Present Value property.

2. Write a value of “1” to the Ref2/Ref1 Binary Value object (BV12)

Present Value property.

Changing Motor Rotation Direction

To command a reverse direction of motor rotation when the drive is running, write a value of “1” to the Rev/Fwd Binary Value object (BV11) Present Value property. To command a forward direction when the drive is running, write a value of “0” (zero) to the Rev/Fwd Binary Value object (BV11) Present Value property.

Clearing a Drive Fault

To clear a drive fault, write a value of “1” to the Clear Faults Binary Value object (BV13) Present Value property.

Using BACnet Objects 4-3

Supported BACnet Objects

The type of drive used on the network determines the specific BACnet objects that are supported. Refer to Table 4.A for descriptions of the BACnet objects and the drives supporting those objects.

No. Name and Description Details

01 [Reset Module]

No action if set to “Ready.” Resets the adapter if set to “Reset Module.” Restores the adapter to its factory default settings if set to “Set Defaults.” This parameter is a command. It will be reset to “0 = Ready” after the command has been performed.

ATTENTION: Risk of injury or equipment damage exists. If the adapter is transmitting I/O that controls the drive, the drive may fault when you reset the adapter. Determine how your drive will respond before resetting a connected

adapter.

Parameter

No. Name and Description Details

02 [Comm Loss Action]

Sets the action that the adapter and drive will take if the adapter detects that network communications have been disrupted. This setting is effective only if I/O that controls the drive is transmitted through the adapter.

ATTENTION: Risk of injury or equipment damage exists. Parameter 02 - [Comm Loss Action] lets you determine the action of the adapter and connected drive if

communications are disrupted. By default, this parameter faults the drive. You

can set this parameter so that the drive continues to run. Precautions should be taken to ensure that the setting of this parameter does 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 drive).

Default: 0 = Fault Values: 0 = Fault

Type: Read/Write Reset Required: No

1 = Stop 2 = Zero Data 3 = Hold Last 4 = Send Flt Cfg

03 [Comm Loss Time]

Sets the communication loss timeout period in seconds. The value zero disables this feature.

ATTENTION: Risk of injury or equipment damage exists. Parameter 03 - [Comm Loss Time] lets you determine how long it will take the adapter to detect network

communication losses. By default, this parameter sets the timeout to ten (10)

seconds. You can set it so that the duration is shorter, longer, or disabled. When set to disabled, this also disables adapter Parameter 02 - [Comm Loss Action]. Therefore, a communications fault action will be ignored. Take precautions to ensure that the setting does 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).

04 [Flt Cfg Logic]

Sets the Logic Command data that is sent to the drive if Parameter 02 - [Comm Loss Action] is set to “Send Flt Cfg” and network communications are disrupted.

The bit definitions will depend on the product to which the adapter is connected. See the documentation for the drive being used.

05 [Flt Cfg Ref]

Sets the Reference data that is sent to the drive if Parameter 02 - [Comm Loss Action] is set to “Send Flt Cfg” and communications are disrupted.

06 [Baud Rate Cfg]

Sets the baud rate (kilobits per second) at which the adapter communicates. (Updates Parameter 07 - [Baud Rate Act] after a reset.)

D-2 Routing Capability for Networked Drives

Notes:

A Adapter

Devices such as drives, controllers, and computers usually require an adapter to provide a communication interface between them and a network such as BACnet MS/TP. An adapter reads data on the network and transmits it to the connected device. It also reads data in the device and transmits it to the network.

The 20-COMM-B adapter connects PowerFlex 7-Class drives to a BACnet MS/TP network. Adapters are sometimes also called “cards,” “embedded communication options,” “gateways,” “modules,” and “peripherals.”

B BACnet MS/TP

BACnet is a data communication protocol for b control networks. BACnet MS/TP (master-slave/token-passing) is a specific type of BACnet network designed to run at speeds of 1 Mbps or less over twisted pair wiring.

Baud Rate

The speed at which data is transferred on the network. Each device on a network must be set for the same baud rate.

uilding automation and

Glossary

Bus Off

A condition that occurs when an abnormal rate of errors is detected in a device. The bus off device cannot receive or transmit messages on the network. This condition is often caused by corruption of the network data signals due to noise or data rate mismatch.

C ControlFLASH

D DPI (Drive Peripheral Interface)

ControlFLASH is an Allen-Bradley software tool that lets users electronically update firmware on printed circuit boards. The tool takes advantage of the growing use of flash memory (electronic erasable chips) across industrial control products.

A second generation peripheral communication interface used by various Allen-Bradley drives and power products, such as PowerFlex 7-Class drives. It is a functional enhancement to SCANport.

Glossary-2

DPI Peripheral

A device that provides an interface between DPI and a network or user. Peripheral devices are also referred to as “adapters” and “modules.” The 20-COMM-B, 1203-SSS or 1203-USB converter, and PowerFlex 7-Class HIMs (20-HIM-xxx) are examples of DPI peripherals.

DPI Product

A device that uses the DPI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a PowerFlex 7-Class drive is a DPI product. In this manual, a DPI product is also referred to as “drive” or “host.”

DriveExplorer Software

DriveExplorer software is a tool for monitoring and configuring Allen-Bradley products and adapters. It can be run on computers running various Microsoft Windows operating systems. DriveExplorer (version

3.xx or higher) can be used to configure this adapter and PowerFlex drives. Information about DriveExplorer software and a free lite version can be accessed at http://www.ab.com/drives/driveexplorer.

DriveTools SP Software

A software suite designed for running on various Microsoft Windows operating systems. This software suite provides a family of tools, including DriveExecutive (version 3.01 or higher), that you can use to program, monitor, control, troubleshoot, and maintain Allen-Bradley products. DriveTools SP (version 1.01 or higher) can be used with PowerFlex drives. Information about DriveTools SP can be accessed at http://www.ab.com/drives/drivetools.

E EDS (Electronic Data Sheet) Files

EDS files are simple text files that are used by network configuration tools to describe products so that you can easily commission them on a network. EDS files describe a product device type, revision, and configurable parameters. EDS files for many Allen-Bradley products can be found at http://www.ab.com/networks/eds.

F Fault Action

A fault action determines how the adapter and connected drive act when a communications fault (for example, a cable is disconnected) occurs.

Fault Configuration

When communication is disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond with a

user-defined fault configuration. The user sets the data that is sent to the drive using specific fault configuration parameters in the adapter. When a fault action parameter is set to use the fault configuration data and a fault occurs, the data from these parameters is sent as the Logic Command and Reference.

Flash Update

The process of updating firmware in a device. The adapter can be flash updated using the Allen-Bradley software tool ControlFLASH, the built-in flash capability of DriveExplorer (version 4.01 or higher), or when the adapter is installed in a DPI External Comms Kit, the X-Modem protocol and a 1203-SSS converter (version 3.xx or higher firmware).

H HIM (Human Interface Module)

A device that can be used to configure and control a drive. PowerFlex 7-Class HIMs (20-HIM-xxx) can be used to configure PowerFlex 7-Class drives and connected peripherals.

Hold Last

When communication is disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond by holding last. Hold last results in the drive receiving the last data received via the network connection before the disruption. If the drive was running and using the Reference from the adapter, it will continue to run at the same Reference.

Glossary-3

I I/O Data

I/O data, sometimes called “implicit messages” or “input/output,” transmit time-critical data such as a Logic Command and Reference. The terms “input” and “output” are defined from the controller’s point of view. Output is produced by the controller and consumed by the adapter. Input is produced by the adapter and consumed by the controller.

L Logic Command/Logic Status

The Logic Command is used to control the PowerFlex drive (for example, start, stop, direction). It consists of one 16-bit word of output to the adapter from the network. The definitions of the bits in this word depend on the drive.

The Logic Status is used to monitor the PowerFlex drive (for example, operating state, motor direction). It consists of one 16-bit word of input

Glossary-4

from the adapter to the network. The definitions of the bits in this word depend on the drive.

M MAC Address

Each device on a network must have a unique MAC address to identify it. On BACnet MS/TP networks, devices can have MAC addresses between 0 and 127 if the network is set up to accommodate that number of devices.

N NVS (Non-Volatile Storage)

NVS is the permanent memory of a device. Devices such as the adapter and drive store parameters and other information in NVS so that they are not lost when the device loses power. NVS is sometimes called “EEPROM.”

P PCCC (Programmable Controller Communications Command)

PCCC is the protocol used by some controllers to communicate with devices on a network. Some software products (for example, DriveExplorer and DriveExecutive) also use PCCC to communicate.

Ping

A message that is sent by a DPI product to its peripheral devices. They use the ping to gather data about the product, including whether it can receive messages and whether they can log in for control.

PowerFlex 7-Class (Architecture-Class) Drives

The Allen-Bradley PowerFlex 7-Class (Architecture-Class) family of drives for use on BACnet MS/TP networks include the PowerFlex 70 (standard and enhanced control), PowerFlex 700 (standard and vector control), PowerFlex 700 Series B (standard and vector control), and PowerFlex 700H. These drives can be used for applications ranging from

0.37 kW (0.5 HP) to 3,000 kW (4,000 HP).

R Reference/Feedback

The Reference is used to send a setpoint (for example, speed, frequency, torque) to the drive. It consists of one word of output to the adapter from the network. The size of the word (either a 16-bit word or 32-bit word) is determined by the drive.

Feedback is used to monitor the speed of the drive. It consists of one word of input from the adapter to the network. The size of the word (either a 16-bit word or 32-bit word) is determined by the drive.

S Status Indicators

Status indicators are LEDs that are used to report the status of the adapter, network, and drive. They are on the adapter and can be viewed on the front cover of the drive when the drive is powered.

T Type 0 Control

When transmitting I/O, the adapter can use different types of messages for control. The Type 0 events help Allen-Bradley personnel identify the type of messages that an adapter is using.

Z Zero Data

When communications are disrupted (for example, a cable is disconnected), the adapter and drive can respond with zero data. Zero data results in the drive receiving zero as values for Logic Command and Reference data. If the drive was running and using the Reference from the adapter, it will stay running but at zero Reference.
