Chapter 1
Getting Started
The adapter is intended for installation into a PowerFlex 7-Class drive and
is used for network communication. The 20-COMM-C Series B coax
adapter, firmware 2.xxx or later, or 20-COMM-Q Series A fiber adapter,
firmware 2.xxx or later, can also be installed in an External DPI Comms Kit
(20-XCOMM-DC-BASE).
For PowerFlex 750-Series drives, we recommend using the 20-750-CNETC
Coaxial ControlNet option module instead of the 20-COMM-C adapter.
However, this manual does include information on using the 20-COMM-C
or 20-COMM-Q adapter with PowerFlex 750-Series drives—but there are
operating limitations. For details, see Compatible Products

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 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 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 adapter. 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
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.
Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action]
let you determine the action of the adapter and connected drive if
communication is disrupted or the controller is idle. 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).
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.

Configuring and 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 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.
The following steps in this section assume that the drive will receive the
Logic Command and Reference from the network.
1. Use drive Parameter 090 - [Speed Ref A Sel] to set the drive speed
Reference to ‘22’ (DPI Port 5).
Installing the Adapter 2-9
2. If hard-wired discrete digital inputs are not used to control the drive,
verify that unused digital input drive Parameters 361 - [Dig In1 Sel] and
362 - [Dig In2 Sel] are set to ‘0’ (Not Used).
3. 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.
TIP: For PowerFlex 750-Series drives, use drive Parameter 545 [Speed Ref A Sel] to set the drive speed Reference:
a. Set the Port field to ‘Port 0 - PowerFlex 75x’.
b. Set the Parameter field to point to the port (slot) in which the

Setting the Node Address
Setting the I/O Configuration
If the adapter Node Address switches (Figure 2.1) are set to ‘00’ (Program)
the value of Parameter 03 - [CN Addr Cfg] determines the node address.
When in any other combination of positions, the Node Address switches
determine the node address.
1. Set the value of Parameter 03 - [CN Addr Cfg] to a unique node
address.
2. Reset the adapter (see Resetting the Adapter
When the node address is correctly configured and the adapter is connected
to an operational network, the NET A status indicator should be steady
green or flashing green.
The I/O configuration determines the data that is sent to and from the drive.
Logic Command/Status, Reference/Feedback, and Datalinks may be
enabled or disabled. (Datalinks allow you to read/write directly to
parameters in the drive using implicit I/O.) A ‘1’ enables the I/O and a ‘0’
disables the I/O.

2. If a controller is used to control the drive, set adapter Parameters 25 [M-S Input] and 26 - [M-S Output] for Master-Slave Hierarchy.
For details, see Setting Master-Slave Hierarchy
3. If Logic Command/Reference is enabled, configure the parameters in
the drive to accept the Logic Command and Reference from the adapter.
For example, set Parameter 90 - [Speed Ref A Sel] in a PowerFlex 70 or
700 drive to ‘22’ (DPI Port 5) so that the drive uses the Reference from
the adapter. Also, verify that the mask parameters (for example,
Parameter 276 - [Logic Mask]) in the drive are configured to receive the
desired logic from the adapter. See the documentation for your drive for
details.

See Chapter
4, Configuring the I/O.
Setting the Reference Adjustment
A Reference Adjustment is a percent scaling factor for the Reference from
the network. It can be set between 0.00…200.00% to allow the drive’s
Reference to either match the network Reference (equal to 100.00%), scale
below the network Reference (less than 100.00%), or scale above the
network Reference (more than 100.00%).
ATTENTION: To guard against equipment damage and/or
personal injury, note that changes to adapter Parameter 27 - [Ref
Adjust] take effect immediately. A drive receiving its Reference
from the adapter will receive the newly scaled Reference,
resulting in a change of speed.
If the adapter is receiving a Reference, set Parameter 27 - [Ref Adjust] to
the desired scaling factor.
The adjustment takes effect as soon as it is entered.
Setting a Fault Action
By default, when I/O communication is disrupted (for example, a cable is
disconnected) or the controller is idle (in program mode or faulted), 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 Parameter 10 - [Comm Flt
Action]
• An idle controller by using Parameter 11 - [Idle Flt Action]
ATTENTION: Risk of injury or equipment damage exists.
Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action]
let you determine the action of the adapter and connected drive if
I/O communication is disrupted or the controller is idle. 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 faulted controller).

Changes to these parameters take effect immediately. A reset is not
required.
If communication is disrupted and then is re-established, the drive will
automatically receive commands over the network again.
Setting the Fault Configuration Parameters
When setting Parameter 10 - [Comm Flt Action] or 11 - [Idle Flt Action]
to ‘Send Flt Cfg’, the values in the following parameters are sent to the drive
after an I/O communication fault and/or idle fault occurs. You must set
these parameters to values required by your application.
Parameter Description
15 - [Flt Cfg Logic] A 16-bit value sent to the drive for Logic Command.
16 - [Flt Cfg Ref] A 32-bit value (0…4294967295) sent to the drive as a Reference or Datalink.
17 - [Flt Cfg x1 In]
through
24 - [Flt Cfg x2 In]
Changes to these parameters take effect immediately. A reset is not
required.
Important: If the drive uses a 16-bit Reference or 16-bit Datalinks, the most
significant word of the value must be set to zero (0) or a fault will occur.

Resetting the Adapter
Changes to switch settings and some adapter parameters require that you
reset the adapter before the new settings take effect. You can reset the
adapter by power cycling the drive or by using Parameter 09 - [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 09 - [Reset Module] to ‘1’ (Reset Module).
When you enter ‘1’ (Reset Module), the adapter will be immediately reset.
When you enter ‘2’ (Set Defaults), the adapter will set all adapter
parameters to their factory-default values. After performing a Set Defaults,
enter ‘1’ (Reset Module) so that the new values take effect. The value of this
parameter will be restored to ‘0’ (Ready) after the adapter is reset.
Viewing the Adapter Status Using Parameters
The following parameters provide information about the status of the
adapter. You can view these parameters at any time.
Parameter Description
04 - [CN Addr Act] The node address used by the adapter. This will be one of the following values:
• The address set by the rotary switches.
• The value of Parameter 03 - [CN Addr Cfg].
• An old address of the switches or parameter if they have been changed and
the adapter has not been reset.
06 - [CN Rate Act] The data rate used by the adapter.
07 - [Ref/Fdbk Size] The size of the Reference/Feedback. It will either be 16 bits or 32 bits. It is set
in the drive and the adapter automatically uses the correct size.
08 - [Datalink Size] The size of the Datalinks. It will either be 16 bits or 32 bits. It is set in the drive
and the adapter automatically uses the correct size.
12 - [CN Active Cfg] Source from which the adapter node address is taken. This will be either ‘0’
(Switches) or ‘1’ (EEPROM) in which the address from Parameter 03 - [CN
Addr Cfg] is stored. The source is determined by the settings of the adapter
Node Address switches.
14 - [DPI I/O Act] The Reference/Feedback and Datalinks used by the adapter. This value is the
same as Parameter 13 - [DPI I/O Cfg] unless the parameter was changed

Configuring the I/O 4-5
There are three ways to add the adapter into the I/O configuration:
• Drive Add-on Profiles (RSLogix 5000 software, version 16.00 or later)
• Classic Profile (RSLogix 5000 software, versions 13.00…15.00)
• Generic Profile (RSLogix 5000 software, all versions)
These are described in separate sections below. If your version of RSLogix
5000 software supports drive Add-on Profiles, we recommend that you use
this method.
Using RSLogix 5000 Drive Add-on Profiles, Version 16.00 or Later
When compared to using the RSLogix 5000 Classic Profile (versions
13.00…15.00) or Generic Profile (all versions), the RSLogix 5000 drive
Add-on Profiles provide the following advantages:
• Profiles for specific drives that provide descriptive controller tags for
basic control I/O words (Logic Command/Status and Reference/
Feedback) and Datalinks. Additionally, Datalinks automatically take the
name of the drive parameter to which they are assigned. These profiles
virtually eliminate I/O mismatch errors and substantially reduce drive
configuration time.
• New Drive tab eliminates the need for a separate drive software
configuration tool.
• Drive configuration settings are saved as part of the RSLogix 5000
software, version 16.00 or later, project file (.ACD) and also downloaded
to the controller.
• Drive Add-on Profiles can be updated anytime. When a new drive is
used, or to benefit from new updates for Add-on Profiles, you will need
the newest Add-on Profile update. Go to http://www.ab.com/support/
abdrives/webupdate to download the latest RSLogix 5000 drive Add-on
Profile. To determine your drive Add-on Profile version, see
Allen-Bradley Knowledgebase document #65882.
Add the Drive/Adapter to the I/O Configuration
To transmit data between the bridge and the drive, you must add the drive as
a child device to the parent bridge. In this example, RSLogix 5000 software,
version 20.00 is used with drive Add-on Profile version 4.04.

6. In the Module Definition screen, edit the following information.
Box Setting
Revision The major and minor revision of the firmware (database) in the drive. If the
drive’s major and minor revision is not available, the drive database is not
installed on your computer. To get the correct database revision, use one of the
following buttons at the bottom left of the Module Definition screen:
• Create Database: Creates a database from an online network drive. Clicking
this button displays an RSLinx software RSWho window. Browse to the
online drive (for this example, PowerFlex 70 EC), select it, and click OK. The
database will be uploaded and stored on the computer. Thereafter, close the
Module Definition screen and then re-open it to display the new revision.
• Web Update: When a drive is not available online, opens the Allen-Bradley
Drives Web Updates website to download a specific database file. After
downloading the file, close the Module Definition screen and then re-open it
to display the new revision.
• Match Drive: Use this button when the drive being added to the network
matches the drive profile (revision, rating, configuration settings, and so forth)
of an existing online network drive. Click this button to conveniently create a
duplicate drive profile from the online drive, and automatically load this
identical information into the Module Definition screen. This eliminates the
need to manually enter the information each time a new drive with a
matching profile is added to the network.
Electronic
Keying
Compatible Module. The ‘Compatible Module’ setting for Electronic Keying
ensures that the physical module is consistent with the software configuration
before the controller and bridge make a connection. Therefore, ensure that you
have set the correct revision in this screen. See the online Help for additional
information on this and other Electronic Keying settings. If keying is not required,
select ‘Disable Keying’. Drives do not require keying, and so ‘Disable Keying’ is
recommended.

Parameters. When the Connection field is set to ‘Parameters via Datalinks’,
‘Parameters’ is automatically selected. When the Connection field is set to
‘Datalinks’, you must select the number of Datalinks required for your application
in the ‘Data Format’ field.
In the Input Data column, assigns selected drive parameters to be READ by the
controller. In the Output Data column, assigns selected drive parameters to be
WRITTEN by the controller.
When this box is checked, sorts the Input Data and Output Data assigned
parameters by name and then by number, and enables parameter search by
name. When unchecked, sorts the assigned parameters by parameter number
and then by name, and enables parameter search by number.
Conveniently selects the speed reference for the drive to come from the
network. This box is checked by default.
When a 32-bit parameter is selected for Input Data or Output Data for a
drive with 16-bit Datalinks, two contiguous Datalinks (for example, x1
and x2, where x = A, B, C or D) are automatically assigned as a pair to
represent that parameter. See Datalink examples in the screen shown on
the previous page. For more information on Datalinks, see Using
Datalinks on page 5-11.
On the Module Definition screen, notice that the automatically-assigned
controller tags DriveStatus, OutputFreq, DriveLogicRslt, and
CommandedFreq are always used.
When a Datalink is enabled, the following 20-COMM-C or
20-COMM-Q adapter I/O parameters are automatically set:
– Parameter 13 - [DPI I/O Cfg] turns on the enabled Datalink bit so
the 20-COMM-C or 20-COMM-Q adapter will communicate that
Datalink’s information with the drive.
– Parameter 25 - [M-S Input] turns on the enabled Datalink bit so the
20-COMM-C or 20-COMM-Q adapter will input that Datalink’s
information from the controller.
– Parameter 26 - [M-S Output] turns on the enabled Datalink bit so
the 20-COMM-C or 20-COMM-Q adapter will output that
Datalink’s information to the controller.

recommend keeping the default value of 20.0 milliseconds.
The ‘Inhibit Module’ box, when checked, inhibits the module from
communicating with the RSLogix 5000 project. When the ‘Major Fault

Using the RSLogix 5000 Classic Profile, Versions 13.00…15.00
When compared to using the RSLogix 5000 Generic Profile (all versions),
the RSLogix 5000 Classic Profile provides these advantages:
• Profiles for specific drives (Figure 4.3
tags for basic control I/O words (Logic Command/Status and Reference/
Feedback). The controller tags for Datalinks, however, have
non-descriptive UserDefinedData[n] names.
• Improved I/O configuration—no I/O assembly configuration required.
Basic control I/O is defined, but Datalinks still need to be configured/
mapped.
• The Setup tab includes a DriveExecutive icon link to conveniently
launch DriveExecutive software (when installed on computer) to match
the adapter I/O configuration with the controller, and to assign the
Datalink parameters in the drive. This reduces I/O mismatches.
TIP: Because the RSLogix 5000 Classic Profile has been significantly
improved upon by RSLogix 5000 Drive Add-on Profiles, version 16.00 or
later, we recommend using RSLogix 5000 Drive Add-on Profiles to take
advantage of their benefits (more intuitive, time saving, and less likely to
make I/O configuration errors).

) that provide descriptive controller
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
4-18 Configuring the I/O
When Datalinks are used, you must enable the desired Datalinks and assign
names to their non-descriptive controller tags. When a Datalink is enabled,
you must set the following adapter I/O parameters:
• Parameter 13 - [DPI I/O Cfg] turns on the enabled Datalink bit so the
20-COMM-C or 20-COMM-Q adapter will communicate that Datalink’s
information with the drive.
• Parameter 25 - [M-S Input] turns on the enabled Datalink bit so the
20-COMM-C or 20-COMM-Q adapter will input that Datalink’s
information from the controller.
• Parameter 26 - [M-S Output] turns on the enabled Datalink bit so the
20-COMM-C or 20-COMM-Q adapter will output that Datalink’s
information to the controller.
When using Datalinks, up to 8 drive [Data In xx] parameters (300…307)
and/or up to 8 [Data Out xx] parameters (310…317) must be assigned to
point to the appropriate drive parameters for your application.
Important:To change the I/O Not Responding box in the upper-left of the
RSLogix 5000 window from flashing green to steady green,
and to remove the yellow warning symbols displayed in the
treeview under the I/O Configuration folder and drive profile,
follow the procedure in Use RSNetworx for ControlNet
Software to Save the I/O to the Bridge on page 4-13.
Using the RSLogix 5000 Generic Profile, All Versions
We recommend that you use the basic RSLogix 5000 Generic Profile for
only the following reasons:
• A specific drive profile in other versions of RSLogix 5000 software is
unavailable.
• Users are already familiar with a drive Generic Profile and do not want to
convert an existing project to a Classic Profile, versions 13.00…15.00, or
to a drive Add-on Profile (RSLogix 5000 software, version 16.00 or
later.)
• A project must maintain specific revision level control.
• The controller cannot be taken offline. RSLogix 5000 software, version
16.00 or later, enables the drive Generic Profile to be added while the
controller is online and in the Run mode.

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

On CIP-based networks, including ControlNet, I/O connections are used to
transfer the data which controls the PowerFlex drive and sets its Reference.
I/O can also be used to transfer data to and from Datalinks in PowerFlex
7-Class drives.
The adapter provides many options for configuring and using I/O, including
the following:
• Configuring the size of I/O by enabling or disabling the Logic
Command/Reference and Datalinks
• Setting a Master-Slave hierarchy

5-2 Using the I/O
Understanding the I/O Image
The terms ‘input’ and ‘output’ are defined from the controller’s point of
view. Therefore, output I/O is data that is produced by the controller and
consumed by the adapter. Input I/O is status data that is produced by the
adapter and consumed as input by the controller. The I/O image will vary
based on the following:
• Size (either 16-bit or 32-bit) of the Reference/Feedback words and
Datalink words used by the drive. To determine the size of the
Reference/Feedback and Datalinks, view adapter Parameters 07 - [Ref/
Fdbk Size] and 08 - [Datalink Size]. For information to access
parameters, see Using the PowerFlex 7-Class HIM to Access
Parameters on page 3-2.
• Configuration of I/O (Parameter 13 - [DPI I/O Cfg]). If all I/O is not
enabled, the image is truncated. The image always uses consecutive
words starting at word 0.
• ControlLogix/CompactLogix Controllers only—The drive profile
used in RSLogix 5000 software (drive Add-on Profile in version 16.00 or
later, Classic Profile in versions 13.00…15.00, or Generic Profile in all
versions).
ControlLogix Controller Image
Because the drive Add-on Profile in RSLogix 5000 software, version 16.00
or later, and the Classic Profile, versions 13.00…15.00, provide descriptive
controller tags, the I/O image (tag size and location) is automatically

Using Logic Command/ Status
Using Reference/Feedback
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
The Logic Command is a 16-bit word of control data produced by the
controller and consumed by the adapter. The Logic Status is a 16-bit word
of status data produced by the adapter and consumed by the controller.
PowerFlex 750-Series drives have a 32-bit Logic Command/Status—but
when using a 20-COMM-C or 20-COMM-Q adapter only the first 16 bits
can be used.
This manual contains the bit definitions for most compatible products
available at the time of publication in Appendix
Word s. For other products, see their documentation.
The Reference is produced by the controller and consumed by the adapter.
The Feedback is produced by the adapter and consumed by the controller.
The size of the Reference/Feedback is determined by the drive and can be
displayed with adapter Parameter 07 - [Ref/Fdbk Size].
Size Valid Values
16-bit -32768 to 32767
32-bit -2147483648 to 2147483647
D, Logic Command/Status
Using the I/O 5-9
When the Reference and Feedback are enabled, and a ControlLogix
controller with a drive Add-on Profile or Classic Profile is used, specific
controller tags are automatically created, sized (16-bit or 32-bit), and placed
in the I/O image.
PowerFlex 70/700/700H and PowerFlex 700L Drives with 700 Control
The Reference/Feedback value is a scaled engineering value; it is not in Hertz
or RPM. The Reference uses a ‘32767’ scale. The ‘32767’ endpoint of the
scale is equal to the value of drive parameter 55 - [Maximum Freq], which
has a default value of 130 Hz. For these drives, default scaling is 0…15123
which is equal to 0…60.0 Hz. This is based on the formula shown below.
Reference/Feedback scaling is limited by drive parameter 82 - [Maximum
Speed]. If the default value of 60 Hz. for parameter 82 - [Maximum Speed] is
changed, the speed Reference/Feedback scaling also changes. To determine
Reference/Feedback scaling, use the following formula:
(Parameter 82 ÷ Parameter 55) * 32767 = Scaling
Using drive parameter 82 and 55 default values, speed Reference/Feedback
scaling is:
(60 Hz ÷ 130 Hz) * 32767 = 15123
Therefore, 0…15123 = 0…60.0 Hz.
If parameter 82 - [Maximum Speed] is changed to 90 Hz, then:
(90 Hz ÷ 130 Hz) * 32767 = 22685
Therefore, 0…22685 = 0…90.0 Hz.
A graphic representation of this Reference/Feedback scaling is shown below.

For PowerFlex 70 drives with enhanced control, firmware 2.xxx or later, or
PowerFlex 700 drives with vector control, firmware 3.xxx or later, drive
parameter 298 - [DPI Ref Select] was added to simplify scaling for the
speed Reference/Feedback. When drive parameter 298 - [DPI Ref Select] is
set to its default ‘0’ (Max Freq), the speed Reference/Feedback scaling is as
shown above. However, when parameter 298 - [DPI Ref Select] is set to ‘1’
(Max Speed), the speed Reference/Feedback scaling is equal to parameter
82 - [Max Speed]:
Scaling = (Parameter 82 ÷ Parameter 55) * 32767
Parameter 82 = Scaling
Par. 82 - [Maximum Speed]
327672268515123
Using the parameter 82 default value, speed Reference/Feedback scaling is:

Publication 20COMM-UM003F-EN-P
5-10 Using the I/O
If parameter 82 - [Maximum Speed] is changed to 90 Hz, then:
90 Hz = 32767
Speed Feedback uses the same scaling as the speed Reference.
TIP: For PowerFlex 700 drives with vector control, firmware 3.xxx or later,
parameter 299 - [DPI Fdbk Select] enables you to select the feedback data
coming from the drive over DPI. The default is ‘Speed Fdbk’ in Hz or RPM
determined by parameter 079 - [Speed Units]. The data selection for
parameter 299 is also displayed on the 1st line of the HIM and on
DriveExplorer and DriveExecutive software screens in the drive status area
of the screen.
PowerFlex 700S and PowerFlex 700L Drives with 700S Control
The Reference/Feedback value is:
32767 = Base Motor Speed
The base speed is set using drive parameter 4 - [Motor RPM]. To set a speed
Reference/Feedback above base speed, a value greater than 32767 must be
entered.
For 16-bit processors, such as PLC-5 and SLC 500 controllers, the data
requires manipulation to set a speed Reference above 32767 or below
-32767. Please see the PowerFlex 700S AC Drives Phase II Control
Reference Manual, publication PFLEX-RM003, in the Chapter 1
‘Communications’ section. Then go to the ‘PLC 5 or SLC System’
subsection and see the ‘Reference/Feedback Programming’ sub-subsection.
PowerFlex 753/755 Drives
The Reference/Feedback value is Hz x 1000 or RPM x 1000. Drive
parameter 300 - [Speed Units] determines whether the scaling is Hz or
RPM. The default scaling is Hz, where 0…60,000 equates to 0…60.000 Hz.
When parameter 300 is set to RPM, then 0…1,765,000 equates to
0…1765.000 RPM.
For 16-bit processors, such as PLC-5 and SLC 500 controllers, the data
requires manipulation to set a speed Reference above 32767 or below
-32767. Please see the PowerFlex 700S AC Drives Phase II Control
Reference Manual, publication PFLEX-RM003, in the Chapter 1
‘Communications’ section. Then go to the ‘PLC 5 or SLC System’
subsection and see the ‘Reference/Feedback Programming’ sub-subsection.

PowerFlex Digital DC Drives
The Reference/Feedback value is:
25000 = Maximum Reference Speed
The maximum Reference speed is set using drive parameter 45 - [Max Ref
Speed].
Using Datalinks
A Datalink is a mechanism used by PowerFlex drives to transfer data to and
from the controller. Datalinks allow a drive parameter value to be read or
written without using an Explicit Message. When enabled, each Datalink
occupies two 16-bit or 32-bit words in both the input and output image. Use
adapter Parameter 08 - [Datalink Size] to determine whether the drive
uses 16-bit or 32-bit words for Datalinks.
Rules for Using Datalinks
• Each set of Datalink parameters in a PowerFlex drive can be used by
only one adapter. If more than one adapter is connected to a single drive,
multiple adapters cannot use the same Datalink.
• Parameter settings in the drive determine the data passed through the
Datalink mechanism. See the documentation for your drive.
• When you use a Datalink to change a value, the value is not written to
the Nonvolatile Storage (NVS) memory. The value is stored in volatile
memory and lost when the drive loses power. Thus, use Datalinks when
you need to change a value of a parameter frequently.
Datalink Scaling
PowerFlex 70/700/700H Drives and PowerFlex 700L Drives with 700 Control
When using RSLogix 5000 software, version 16.00 or later, Datalink
scaling is done automatically. However, when using RSLogix 5000
software, version 15.00 or earlier—or when using a PLC-5 or SLC 500
controller—Datalink scaling is not automatic and uses whole numbers
(INTs or DINTs). See the drive documentation to determine the unit
resolution for the associated parameter Datalink. For example, PowerFlex
700VC drive parameter 3 - [Output Current] has a 0.1 unit resolution.
Because Datalink scaling uses whole numbers, the Output Current value is
multiplied by 10 in the adapter and then sent over the network. Suppose the
actual Output Current value is 35.5 amps. Reading the associated parameter
Datalink received by the controller, the value would be 355. By using ladder
logic, divide the value by 10 in the controller to get the correct scaling. See
the drive documentation to determine if the Datalink parameter is a 16-bit or
32-bit parameter.

5-12 Using the I/O
PowerFlex 700S, PowerFlex 700L with 700S Control, PowerFlex 753/755, and
PowerFlex Digital DC Drives
When using RSLogix 5000 software, version 16.00 or later, Datalink
scaling is done automatically. However, when using RSLogix 5000
software, version 15.00 or earlier—or when using a PLC-5 or SLC 500
controller—Datalinks require scaling in the following way. Parameters are
either 16-bit or 32-bit integers or REALs. When the parameter is a 32-bit
integer, the data needs to be copied using a COP command to a DINT tag.
(Because PLC-5 and SLC 500 controllers do not support 32-bit integers, the
data must be separated into two 16-bit integers.) When the parameter is a
REAL, the data needs to be copied using a COP command to a REAL tag.
See subsequent sections in this chapter for ladder logic examples. See the
drive documentation to determine if the Datalink parameter is a 16-bit or
32-bit integer parameter, or a REAL parameter.
Using 16-Bit Datalinks to Read/Write 32-Bit Parameters
This subsection only pertains to PowerFlex 70 (standard or enhanced
control), PowerFlex 700 (standard control), and PowerFlex 700H drives
which use 16-bit Datalinks. To read or write a 32-bit parameter using 16-bit
Datalinks, typically both Datalinks of a pair (A, B, C, D) are set to the same
32-bit parameter. For example, to read parameter 10 - [Elapsed Run Time]
in a PowerFlex 70 drive, both Datalink A1 Out (Parameter 310) and
Datalink A2 Out (Parameter 311) are set to ‘10’. Datalink A1 Out will
contain the least significant word (LSW) and Datalink A2 Out will contain
the most significant word (MSW).
32-bit data is stored in binary as follows:
MSW 2
LSW 215 through 2
In this example, the parameter 10 - [Elapsed Run Time] value of 6553.9 Hrs
is read as ‘6553.9’ in Datalink A1 Out (Parameter 310) and Datalink A2
Out (Parameter 311).
Datalink Word Parameter Data (Hex)
A1 Out LSW 10 0003
A2 Out MSW 10 0001
Conversion Example:
Parameter 010 - [Elapsed Run Time] = 6553.9 Hrs
MSW = 0001
LSW = 0003

Regardless of the Datalink combination, Datalink x1 Out will always
contain the LSW and Datalink x2 Out will always contain the MSW. In the
following example, the PowerFlex 70 drive parameter 242 - [Power Up
Marker] contains a value of 88.4541 hours.

Example Ladder Logic Program Information
The example ladder logic programs in the sections of this chapter are
intended for and operate PowerFlex 7-Class drives.
Functions of the Example Programs
The example programs enable you to do the following:
• Receive Logic Status information from the drive.
• Send a Logic Command to control the drive (for example, start, stop).
• Send a Reference to the drive and receive Feedback from the drive.
• Send/receive Datalink data to/from the drive.
Logic Command/Status Words
These examples use the Logic Command word and Logic Status word for
PowerFlex 70/700 drives. Information for PowerFlex 750-Series drives has
been added to examples where applicable. See Appendix
The definition of the bits in these words may vary if you are using a
different DPI drive. See the documentation for your drive.

ControlLogix Controller Example
You can use any of RSLogix 5000 software versions to create the ladder
logic. These are described in separate sections below. If your version of
RSLogix 5000 software supports drive Add-on Profiles, we recommend that
you use this method.
Creating Ladder Logic Using the RSLogix 5000 Drive Add-on Profiles, Version 16.00 or Later
Because the drive Add-on Profile automatically created descriptive controller
tags (Figure 4.2
to directly control and monitor the drive without creating any ladder logic
program. However, if you intend to use Human Machine Interface devices
(PanelView, and so forth) to operate the drive and view its status, you will
need to create descriptive user-defined Program tags (Figure 5.1
logic program that will pass the Controller tag data to the Program tags.

Because the RSLogix 5000 Classic Profile has been significantly improved
upon by RSLogix 5000 drive Add-on Profiles, version 16.00 or later, we
recommend using the RSLogix 5000 drive Add-on Profiles to take
advantage of their benefits (more intuitive, time saving, and less likely to
make ladder logic program errors).

TIP: When using a drive that has 16-bit Datalinks (PowerFlex 70,
PowerFlex 700, and PowerFlex 700H drives) to transfer a 32-bit parameter,
two contiguous drive Datalink parameters (for example, Data Out A1/A2,
B1/B2, and so forth) are required. To determine if a parameter is a 32-bit
parameter, see the Parameter section in the drive documentation and look
for a symbol in the ‘No.’ column. (All parameters in PowerFlex 700
Series B drives are 32-bit parameters.) For example, parameter 3 - [Output
Current] in a PowerFlex 70 EC drive is a 32-bit parameter. When using a
drive that has 32-bit Datalinks (PowerFlex 700 VC, PowerFlex 700S, and
PowerFlex 750-Series drives), only one drive Datalink parameter is required
to transfer any parameter.

TIP: When using a drive that has 16-bit Datalinks (PowerFlex 70,
PowerFlex 700, and PowerFlex 700H drives) to transfer a 32-bit parameter,
two contiguous drive Datalink parameters (for example, Data Out A1/A2,
B1/B2, and so forth) are required. To determine if a parameter is a 32-bit
parameter, see the Parameter section in the drive documentation and look
for a symbol in the ‘No.’ column. (All parameters in PowerFlex 700

Understanding PLC-5 Controller Data Table Addresses
Because the PLC-5 controller is a 16-bit platform and is used with the
32-bit 20-COMM-C or 20-COMM-Q adapter, the data will be transposed
from the least-significant word (LSW) to the most-significant word (MSW)
in the controller.
When the I/O was configured (Chapter 4
addresses (N9:0 for input data and N10:0 for output data) were used.
