Features

The features of the Option Module include:

• Captive screws to secure and ground the module to the drive.

• Switches to set a node address and network data rate before applying

power to the drive. Alternately, you can disable the switches and use Option Module parameters to configure these functions.

• Compatibility with various configuration tools to configure the

Option Module and host drive. The tools include the enhanced PowerFlex 7-Class HIM (Human Interface Module) on the drive, and drive-configuration software such as DriveExplorer (version

6.01 or higher) or DriveExecutive (version 5.01 or higher).

• Status indicators that report the status of the Option Module and

network communications. They are visible when the drive cover is removed.

• Parameter-configurable 32-bit Datalinks in the I/O to meet

application requirements (16 for writing data from the network, and 16 for reading data to the network).

• Explicit Messaging and UCMM (Unconnected Message Manager)

support.

• Multiple data exchange methods, including Polled, Cyclic, and

Change of State (COS), to transmit data between the network and Option Module.

• Master-Slave hierarchy that can be set up so that the Option Module

and PowerFlex 750-Series drive transmit data to and from a scanner on the network.

• User-defined fault actions to determine how the Option Module and

connected drive respond to:

– I/O messaging communication disruptions (Comm Flt Action) – Controllers in idle mode (Idle Flt Action) – Explicit messaging disruptions for drive control via PCCC and

the CIP Register Object (Msg Flt Action)

• Faulted node recovery support. You can configure a device even

when it is faulted on the network if you have a configuration tool that uses faulted node recovery and have set the Data Rate switch to position “3.” With this configuration, the Option Module uses parameter settings stored in EEPROM for the data rate and node address instead of switch settings.

• Support for DPI routing, enabling access to any networked

PowerFlex 7-Class drive using DriveExplorer (version 6.01 or higher) to monitor and configure that drive and its connected peripherals.

Understanding Parameter Types

Compatible Products

Required Equipment

The Option Module has two types of parameters:

• Device parameters are used to configure the Option Module to operate

on the network. Device parameters, when viewed using DriveExplorer or DriveExecutive, appear below the 20-750-DNET listing in the treeview in a separate Device Parameters folder . When viewed using the HIM, these parameters appear in the DEV PARAM folder.

• Host parameters are used to configure the Option Module Datalink

transfer and various fault actions with the drive. Host parameters, when viewed using DriveExplorer or DriveExecutive, appear below the 20-750-DNET listing in the treeview in a separate Host Parameters folder. When viewed using the HIM, these parameters appear in the HOST PARAM folder.

At the time of publication, the Option Module is compatible with Allen-Bradley PowerFlex 750-Series drives.

Equipment Shipped with the Option Module

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

ATTENTION: Risk of equipment damage exists. The Option Module 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 Option Module. 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 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 can set these parameters so that the drive continues to run. Precautions should be taken to ensure 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, Inc. does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

2-2 Installing the Option Module

Setting the Node Address Switches

Set the Option Module Node Address switches (bottom two switches – see Figure 2.1

) by rotating the switches to the desired value for each

digit.

Important:Each node on the DeviceNet 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, or disconnect and reconnect the DeviceNet network cable.

Configuring/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.

Publication 750COM-UM002A-EN-P

Page 23

Installing the Option Module 2-7

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

1. Use drive Parameter 545 - [Speed Ref A Sel] to set the drive speed

Reference to the port (slot) in which the Option Module is installed (for example, Port 4 Reference).

2. Verify that drive Parameter 930 - [Speed Ref Source] is reporting

that the source of the Reference to the drive 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 problem occurs, this verification step provides the diagnostic capability to determine whether the drive/Option Module or the network is the cause.

3. If hard-wired discrete digital inputs are not used to control the

drive, verify that all unused digital input parameters are set to “Not Used.”

Commissioning the Option Module

To commission the Option Module, you must set a unique node address on the network. (Refer to Setting the Node Address Switches

page 2-2, and the Glossary for details about node addresses.)

Important:New settings are recognized only when power is applied to

the Option Module or it is reset. After you change parameter settings, cycle power or reset the Option Module.

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

the S or T soft key to scroll to the desired parameter number.

If the Data Rate switch (Figure 2.2) is set to position “3,” the value of Device Parameter 07 - [Net Addr Cfg] determines the node address. When the Data Rate switch is set to any other position, the Node Address switches determine the node address. We recommend that you do not use node address 63 because all new devices on the network use this address as the default address. Also, node address 63 is used for Automatic Device Recovery (ADR).

1. Set the value of Device Parameter 07 - [Net Addr Cfg] to a unique

node address.

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 scanner (1756-DNB, 1771-SDN, 1747-SDN, etc.).

Enabling Datalinks To Write Data

The controller output image (controller outputs-to-drive) can have anywhere from 0 to 16 additional 32-bit parameters (Datalinks). The number of additional parameters is configured using Device Parameter

02 - [DLs From Net Cfg].

Important: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 3 Datalinks to write data. Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

Host Parameters 01 - [DL From Net 01] through 16 - [DL From Net 16] control which parameters in the drive, Option Module, or any other

connected peripheral receive the values from the network. The enhanced PowerFlex 7-Class HIM, DriveExplorer, and DriveExecutive provide user-friendly screens to help 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.

1. Set the value of Device Parameter 02 - [DLs From Net Cfg] to the

number of contiguous controller-to-drive Datalinks that are to be included in the network I/O connection.

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. If the controller is going to be used for speed reference via the Option Module, set Parameter 545 - [Speed Ref A Sel] in a PowerFlex 755 drive to the port in which the Option Module is installed (for 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. Refer to the documentation for your drive for details.

The Option Module is ready to receive input data from the master (controller). You must now configure the controller to recognize and transmit I/O to the Option Module. Refer to Chapter 4

Configuring the I/O

Enabling Datalinks To Read Data

The controller input image (drive-to-controller inputs) can have anywhere from 0 to 16 additional 32-bit parameters (Datalinks). The number of additional parameters is configured using Device Parameter

04 - [DLs To Net Cfg].

Important: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 5 Datalinks to read data. Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

Host Parameters 17 - [DL To Net 01] through 32 - [DL To Net 16] control which parameters in the drive, Option Module, or any other connected peripheral send the values to the network. The enhanced PowerFlex 7-Class HIM, DriveExplorer, and DriveExecutive provide user-friendly screens to help 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:

The Option Module is ready to send output data to the master (controller). You must now configure the controller to recognize and transmit I/O to the Option Module. Refer to Chapter 4

Configuring the I/O

The data exchange is the method that the Option Module uses to exchange data on the DeviceNet network. Polled is the default and is recommended — unless one of the other following data exchanges, which the adapter supports, is more appropriate for your application:

• COS (Change of State) • Polled and COS

• Cyclic • Polled and Cyclic

• Polled

If “Polled and COS” or “Polled and Cyclic” is used, the Option Module transmits and receives the I/O from the polled messages. It transmits only a Logic Status and Feedback in COS or Cyclic messages. Other data is transmitted in Polled messages.

Cyclic and Polled data exchanges are configured in the scanner, so you only need to set the I/O configuration in the Option Module. COS data exchange must be configured in both the Option Module and the scanner. You need to set the I/O configuration and COS parameters in the Option Module.

When you enter “1” (Reset Module), the Option Module will be immediately reset. An alternate method to reset the module is by power cycling the drive. When you enter “2” (Set Defaults), the Option Module will set ALL of its Device and default values. (This is the same as pressing the ALL soft key when using the MEMORY folder method described in Restoring Option

Module Parameters to Factory Defaults on page 3-9.) After performing

a Set Defaults, you must enter “1” (Reset Module) or power cycle the

drive so that the new values take effect. Thereafter, the value of this parameter will be restored to “0” (Ready).

Important:When performing a Set Defaults, the drive may detect a

conflict and then not allow this function to occur. If this happens, first resolve the conflict and then repeat a Set Defaults action.

TIP: If your application allows, you can also reset the Option Module by cycling power to the drive (resetting the drive) or by using the HIM’s Reset Device function located in the drive’s DIAGNOSTIC folder.

Restoring Option Module Parameters to Factory Defaults

As an alternate method, you can restore the Option Module parameters using a MEMORY folder menu item instead of using Device Parameter 14 - [Reset Module] described in Resetting the Option

Module on page 3-8. The MEMORY folder method provides two ways

to restore the Option Module Device and

• ALL—restores ALL Option Module Device and Host parameters to

their factory default values.

• MOST—restores MOST Option Module Device and Host

parameters—except the following which are used for network setup:

– Device Parameter 07 - [Net Addr Cfg] – Device Parameter 09 - [Net Rate Cfg]

To restore Option Module Device and Host parameters to their factory default values:

1. Access the Status screen, which is displayed on HIM power up.

Configuring the I/O

This chapter provides instructions on how to configure a Rockwell Automation ControlLogix controller to communicate with the Option Module and connected PowerFlex drive.

Topic Page

Using RSLinx Classic ControlLogix Example 4-2

Important:Since the Option Module and PowerFlex 750-Series drive

are 32-bit devices, the ControlLogix controller (also a 32-bit platform) is used for example purposes in this chapter and throughout this manual. We recommend using only a 32-bit platform Logix controller with this Option Module and PowerFlex 750-Series drive to simplify configuration and ladder logic programs, and maximize drive performance. If you must use a 16-bit controller (PLC-5, SLC 500, etc.), we recommend using a 20-COMM-D adapter that is mounted onto a 20-750-20COMM Option Card installed in drive Port 6. In this case, refer to the Rockwell Automation Technical Support Knowledgebase web site at

B. Enter the number of bytes that are required for your I/O in the

Input Size and Output Size boxes. For the example in this manual, all 16 [DL From Net xx] and all 16 [DL To Net xx] are used, resulting in an Input Size of “72” and an Output Size of “72.” To determine the byte sizes for your application, either access Option Module Diagnostic Items 7 and 8 respectively or calculate them:

Determining Byte Sizes By Accessing Diagnostic Items 7 and 8

Use the HIM, DriveExplorer or DriveExecutive to access Diagnostic Items 7 and 8. The Option Module automatically calculates the number of bytes for the Input Size and Output Size based on the values of Device Parameters 2 - [DLs From Net Cfg] and 4 - [DLs To Net Cfg] configured in Setting a

Master-Slave Hierarchy (Optional) on page 3-3.

Determining Byte Sizes By Calculation

You can easily calculate the number of bytes for the Input Size and Output Size. Since the Option Module always uses the 32-bit Logic Command, 32-bit Feedback, 32-bit Logic Status, and 32-bit Reference, at least 8 bytes must be set for both the Input Size and Output Size. (A 32-bit word is four bytes.) If any or all of the drive’s sixteen 32-bit Datalinks are used (see

Setting a Master-Slave Hierarchy (Optional)

increase the Input and Output Size settings accordingly. To do this:

– Input Size: Multiply the number of Datalinks used to write data

(value of Device Parameter 02 - [DLs From Net Cfg]) by 4 bytes, and add this result to the minimum 8 bytes. For example, if Parameter 02 has a value of “3,” add 12 bytes (3 x 4 bytes) to the required minimum 8 bytes for a total of 20 bytes.

About I/O Messaging

On CIP-based networks, including DeviceNet, 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 750-Series drives.

The Option Module includes the Logic Command, Logic Status, Reference, and Feedback (all as 32-bit words). This requires 8 bytes for the Input Size and 8 bytes for the Output Size in the controller’s I/O image. This basic I/O must always be configured in the DeviceNet scanner using RSNetWorx for DeviceNet. Additional I/O, if needed, can be set using up to 16 Datalinks to write data and/or up to 16 Datalinks to read data. When using any combination of these Datalinks, add 4 bytes for each Datalink to the basic I/O Input Size and/or Output Size.

Chapter 3 the I/O, discuss how to configure the Option Module and controller on

5-2 Using the I/O

Understanding the ControlLogix Controller 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 Option Module. Input I/O is status data that is produced by the Option Module and consumed as input by the controller. The I/O image will vary based on how many of the drive’s 32-bit Datalinks (Host DL From Net 01-16 and Host DL To Net 01-16) are used.

If all available I/O is not used, the image is truncated. The image always uses consecutive words starting at word 0.

Command/Status, Reference/Feedback, and Datalinks)

Using Logic Command/ Status

The Logic Command is a 32-bit word of control data produced by the controller and consumed by the Option Module. The Logic Status is a 32-bit word of status data produced by the Option Module and consumed by the controller.

When using a ControlLogix controller, the Logic Command word is always DINT 0 in the output image and the Logic Status word is always DINT 0 in the input image.

Using Reference/Feedback

The Reference is a 32-bit REAL (floating point) piece of control data produced by the controller and consumed by the Option Module. The Feedba ck is a 32-bit REAL (floating point) piece of status data produced by the Option Module and consumed by the controller.

The Reference and Feedback values represent engineering units. For example, a 32-bit REAL Reference value of “30.0” equals a Reference of 30.0 Hz. Note that the commanded maximum speed can never exceed the value of drive Parameter 520 - [Max Fwd Speed]. Table 5.B shows example References and their results for a PowerFlex 750-Series drive that has its Parameter 37 - [Maximum Freq] set to 130 Hz and Parameter 520 - [Max Fwd Speed] set to 60 Hz.

When using a ControlLogix controller, the 32-bit REAL Reference word is always DINT 1 in the output image and the 32-bit REAL Feedback word is always DINT 1 in the input image. Because the I/O image is integer-based and the Reference and Feedback are floating point, a COP (Copy) instruction or UDDT is required to correctly write values to the Reference and read values from the Feedback. See the ladder logic program examples in Figure 5.5

5-4 Using the I/O

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 changed without using an Explicit Message. When enabled, each Datalink occupies one 32-bit word in a ControlLogix controller.

The following rules apply when using PowerFlex 750-Series drive Datalinks:

• The target of a Datalink can be any Host parameter, including those

of a peripheral. For example, drive parameter 535 - [Accel Time 1] can be assigned to any or all Option Modules installed in the drive.

• The data passed through the Datalink mechanism is determined by

the settings of:

Device Parameter 02 - [DLs From Net Cfg] Host Parameters 01-16 - [DL From Net 01-16] Device Parameter 04 - [DLs To Net Cfg] Host Parameters 17-32 - [DL To Net 01-16]

Important:A reset is always required after configuring Datalinks so

that the changes take effect.

• When a Datalink I/O connection is active, that Datalink is locked

and cannot be changed until that I/O connection becomes idle or inactive.

• When you use a Datalink to change a value, the value is NOT written

to the Non-Volatile Storage (NVS). 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.

Datalinks for PowerFlex 750-Series peripherals (embedded EtherNet/IP adapter and option modules such as an encoder or a communication module) are locked when the peripheral has an I/O connection with a controller. When a controller has an I/O connection to the drive, the drive does not allow a reset to defaults, configuration download or anything else that could change the makeup of the I/O connection in a running system. The I/O connection with the controller must first be disabled to allow changes to the respective Datalinks.

Depending on the controller being used, the I/O connection can be disabled by:

• Inhibiting the module in RSLogix 5000

• Putting the controller in Program mode

• Placing the scanner in idle mode

• Disconnecting the drive from the network

DeviceLogix Datalinks are also locked while the DeviceLogix program is running. The DeviceLogix program must first be disabled to allow changes to the Datalinks. Set DeviceLogix parameter 53 - [DLX Operation] to “DisableLogic” to disable the logic (the parameter value will then change to “LogicDisabld.”

Performing Explicit Messages

There are five basic events in the Explicit Messaging process. The details of each step will vary depending on the type of controller being used. Refer to the documentation for your controller.

Important:There must be a request message and a response message

for all Explicit Messages, whether you are reading or writing data.

You format the required data and set up the ladder logic program to send an Explicit Message request to the scanner module (download).

The scanner module transmits the Explicit Message Request to the slave device over the network.

The slave device transmits the Explicit Message Response back to the scanner. The data is stored in the scanner buffer.

The controller retrieves the Explicit Message Response from the scanner’s buffer (upload).

The Explicit Message is complete. Note: The scanner module may be integrated with the controller (for example, ControlLogix).

The default setting for Service Type is “Custom,” enabling entry of a Service Code not available from the Service Type pull-down menu. When selecting a Service Type other than “Custom” from the pull-down menu, an appropriate Hex. value is automatically assigned to the Service Code box which grays out (unavailable). When reading 32-bit REAL (floating point) parameters, as in this example, data conversion using COP (Copy) instructions or UDDT’s is required to correctly show the parameter values.

(3)

In this example, we are reading five 32-bit REAL (floating point) parameters. Each parameter being read requires two contiguous DINT registers. Therefore, a controller tag was created with its Data Type field set to “DINT[10].” Also, the Source Length field on the Message Configuration screen must correspond to the selected Data Type in bytes (for this example, 40 bytes for a DINT[10] array). Scattered read messages always assume that every parameter being read is a 32-bit parameter, regardless of its actual size. Maximum message length is 128 bytes which can read up to 16 parameters, regardless of their size.

The controller tag for “Scattered_Read_Response” must be the same size as the controller tag for “Scattered_Read_Request.”

The default setting for Service Type is “Custom,” enabling entry of a Service Code not available from the Service Type pull-down menu. When selecting a Service Type other than “Custom” from the pull-down menu, an appropriate Hex. value is automatically assigned to the Service Code box which grays out (unavailable). When writing to 32-bit REAL (floating point) parameters, as in this example, data conversion using COP (Copy) instructions or UDDT’s is required to correctly write the parameter values.

(2)

(3)

In this example, we are writing to five 32-bit REAL (floating point) parameters. Each parameter being written to requires two contiguous DINT registers. Therefore, a controller tag was created with its Data Type field set to the name of the UDDT of five interleaved DINTs and REALs. Also, the Source Length field on the Message Configuration screen must correspond to the selected Data Type in bytes (for this example, 40 bytes for an array of five scattered real structures. Scattered write messages always assume that every parameter being written to is a 32-bit parameter, regardless of its actual size. Maximum message length is 128 bytes which can write up to 16 parameters, regardless of their size

(4)

The controller tag for “Scattered_Write_Response” must be the same size as the controller tag for “Scattered_Write_Request.”

Sets the mask for the 32-bit Logic Status word. Unless they are masked out, the bits in the Logic Status word are checked for changes when the Option Module is allocated using COS (Change of State). If a bit changes, it is reported as a change in the Change of State operation.

If the mask bit is “0” (Off), the bit is ignored. If the mask bit is “1” (On), the bit is checked.

Important: The bit definitions in the Logic Status word for PowerFlex 750-Series drives are shown in Appendix

12 [COS Fdbk Change]

Sets the amount of acceptable error (positive or negative) that the Feedback word can change before it is reported as a change in the COS (Change of State) operation.

13 [COS/Cyc Interval]

Displays the amount of time that a scanner will wait to check for data in the Option Module.

When COS (Change of State) data exchange has been configured, this is the maximum amount of time between scans. Scans will occur sooner if data changes.

When Cyclic data exchange has been configured, this interval is the fixed time between scans.

14 [Reset Module]

No action if set to “0” (Ready). Resets the Option Module if set to “1” (Reset Module). Restores the Option Module to its factory default settings if set to “2” (Set Defaults). This parameter is a command. It will be reset to “0” (Ready) after the command has been performed.

When performing a Set Defaults, the drive may detect a conflict. If this occurs, the drive will not allow a Set Defaults action. You must resolve the conflict before attempting a Set Defaults action for the Option Module.

Sets the port number and parameter number to which the selected Datalinks should connect. Each selected port/parameter will be written with data received from the network. These are parameters written by the controller (outputs from the controller).

If setting the value manually, the 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 01 of an optional encoder module plugged into drive Port 5. The value for Host Parameter 01 - [DL From Net

01] would be 50001 [(10000 * 5) + 1]. [DL To Net 01]

Sets the port number and parameter number to which the selected Datalinks should connect. Each selected port/parameter will be read and their values transmitted over the network to the controller. These are parameters read by the controller (inputs to the controller).

If setting the value manually, the 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 01 of an optional I/O module plugged into drive Port 4. The value for Host Parameter 17 - [DL To Net 01] would be 40001 [(10000 * 4) + 1].

33 [Comm Flt Action]

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

ATTENTION: Risk of injury or equipment damage exists. Host Parameter 33 - [Comm Flt Action] lets you determine the action of the Option

Module and connected drive if I/O 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 cable).
