Features

The Interbus adapter features the following:

• The adapter is mounted in the PowerFlex drive and receives the required power from the drive. Captive screws are used to secure the adapter to the drive.

• A number of configuration tools can be used to configure the adapter and connected drive. The tools include the PowerFlex HIM on the drive, or drive-configuration software such as DriveExplorer (version 2.01 or higher) or DriveExecutive (version 1.01 or higher).

• Status indicators report the status of the drive, adapter, and network.

• I/O, including Logic Command/Reference and Datalinks, may be

configured for your application using a parameter.

• Explicit messages are supported (PCP Read/Write).

• User-defined fault actions determine how the adapter and PowerFlex

drive respond to communication disruptions on the network.

Safety Precautions

Please read the following safety precautions carefully.

ATTENTION:

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 a Interbus adapter. Failure to comply may result in injury and/or equipment damage.

ATTENTION:

may contain high voltages that can cause injury or death. Remove all

power from the PowerFlex drive, and then verify power has been removed before installing or removing a Interbus adapter.

ATTENTION:

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:

Interbus 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 equipment damage, injury, or death exists. Unpredictable operation may occur if you fail to verify that parameter

settings and switch settings are compatible with your application. Verify that settings are compatible with your application before applying power to the drive.

1. Close the door or reinstall the cover on the drive. Key status

indicators can be viewed on the front of the drive after power has been applied.

Note: Interbus compliance requires different LED functions than what is normally displayed on the front of the drive (Port, Mod, Net A, and Net B Leds). LED labels are provided with the adapter for application to the drive cover.

2. Apply power to the PowerFlex drive. The adapter receives its power

from the connected drive. When you apply power to the product for the first time, the status indicators should be green or off after initialization. Refer to Chapter information.

Configuring the Adapter 3-3

Setting the I/O Configuration

The I/O configuration determines the data that is sent to and from the drive. This is a two part process: enabling/disabling the data transmitted between the adapter and drive, and identifying the data transmitted between the adapter and the scanner.

1. Enable or disable the data transmitted between the adapter and drive.

A “1” enables the I/O A “0” disables the I/O

Set the bits in Parameter 8 - [DPI I/O Config]:

Bit Description

0 Logic Command/Reference (Default) 1 Datalink A 2 Datalink B 3 Datalink C 4 Datalink D 5 - 16 Not Used

Bit 0 is the right-most bit. In Figure 3.1, it is highlighted and equals “1.”

2. If Logic Command/Reference is enabled, configure the parameters in

the drive to accept the logic and Reference from the adapter. For example, set Parameter 90 - [Speed Ref A Sel] in a PowerFlex 70 or 700 drive to “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.

3. If you enabled one or more Datalinks, configure parameters in the

drive to determine the source and destination of data in the Datalink(s). Also, ensure that the Interbus adapter is the only adapter using the enabled Datalink(s).

3-4 Configuring the Adapter

4. Interbus requires the network I/O mapping to be configured first in

the adapter. CMD software will read this configuration online when it is configuring the scanner.

Process Input Data Description (PIDD) words map input data on the network (data seen as inputs to the scanner and controller program). Example input data includes Logic Status, Feedback and Datalinks (Datalink x1 Out). Up to 9 words of input data can be mapped.

Process Output Data Description (PODD) words map output data on the network (data sent as outputs from the scanner and controller program). Example output data includes Logic Command, Reference and Datalinks (Datalink x1 In). Up to 9 words of output data can be mapped.

The following indexes are used to select the I/O data:

Description

Note that Datalink D2 is not used in this example because maximum configuration has been reached. The maximum configuration is shown to illustrate utilizing all 9 words of inputs and 9 words of outputs. Depending on your application needs, any subset of the above example can be implemented.

The corresponding Parameter 8 - [DPI I/O Config] setting would be “11111” for all of the above information to transfer between the adapter and the drive.

5. Reset the adapter. Refer to the Resetting the Adapter

section in this

chapter.

The adapter is ready to receive I/O from the master (i.e., scanner). You must now configure the scanner to recognize and transmit I/O to the adapter. Refer to Chapter

4, Configuring the Interbus Scanner.

3-6 Configuring the Adapter

Setting a Fault 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 6 - [Comm Flt Action].

ATTENTION: Parameters 6 - [Comm Flt Action]

To change the fault action

• Set the values of Parameters to the desired responses:

Value Action Description

0 Fault (default) 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 after a

Changes to the parameter take effect immediately. A reset is not required.

To set the fault configuration parameters

If you set Parameter 6 - [Comm Flt Action] to the “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.

Number Name Description

10 Flt Cfg Logic A 16-bit value sent to the drive for Logic Command. 11 Flt Cfg Ref A 32-bit value (0 – 4294967295) sent to the drive as a 12 – 19 Flt Cfg x1 In

Reference or Datalink. 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.

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

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 the following parameter:

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 product will respond before resetting a connected adapter.

• Set the Parameter 05 - [Reset Module] to Reset Module:

Value Description

0 Ready (Default) 1 Reset Module 2 Set Defaults

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 settings. The value of this parameter will be restored to 0 = Ready after the adapter is reset.

3-8 Configuring the Adapter

The following parameters provide information about how the adapter is configured. You can view these parameters at any time.

Parameter No. Name and Description Details

01 [DPI Port]

Port to which the adapter is connected. This will usually be port 5.

03 [Ref/Fdbk Size]

Size of the Reference/Feedback. The drive determines the size of the Reference/Feedback.

04 [Datalink size]

Size of each Datalink word. The drive determines the size of Datalinks.

09 [DPI I/O Active]

I/O that the adapter is actively transmitting. The value of this parameter will usually be equal to the value of Parameter 13 - DPI I/O Config.
