Introduction

The Interbus module (RECOMM-IBUS) is an embedded communication option for DPI AC drives, such as the SP600 drive. The module is mounted in the drive and receives its required power from the drive and from the network.

The module can be used with other products that implement DPI, a peripheral communication interface. Refer to the documentation for your product for specific information about how it works with the module.

This manual is intended for qualified electrical personnel familiar with installing, programming, and maintaining AC drives and networks.

1.1 Interbus Module Features

The Interbus module features the following:

A number of configuration tools that can be used to configure the

•

module and connected drive. The tools include the LCD Operator Interface Module (OIM) on the drive and drive-configuration software such as VS Utilities (version 1.01 or later)

Status indicators that report the status of the drive

•

communications, module, and network. They are visible both when the cover is opened and when it is closed.

I/O, including Logic Command/Reference and up to four pairs of

•

Datalinks, that may be configured for your application using a parameter.

Explicit messages (PCP Read/Write.)

•

User-defined f ault actio ns that determine ho w the modul e and the

•

drive respond to communicat ion disruptions on the network.

4.1 Configuration Tools

The Interbus module stores parameters and other information in its own non-volatile memory. Therefore, you must access the module to view and edit its parameters. Table 4.1 lists the tools that can be used to access the module parameters.

4.3 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 module and drive, and identifying the data transmitted between the module and the scanner.

Step 1. Enable or disable the data transmitted between the

Interbus Communications Module

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

parameters in the drive to acc ept the Logic and Ref erence from the module. For example, set Speed Ref A Sel (90) in an SP600 drive to “Network” so that the drive uses the Reference from the module. Also, verify that the mask parameters (for example, Manual Mask (286)) in the drive are configured to receive the desired logic from the module.

Step 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 th at the Interbus module is the only module using the enabl ed Datalink(s).

Step 4. Interbus requires the network I/O mapping to be

configured first in the module . CM D softw are wi ll rea d 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 (dat a sent as outpu ts 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.

Description

Note that Datalink D2 is no t used in this e xampl e because maximum conf iguration has been reached. The maxim um configura tion is shown to illustrate utilizin g 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 DPI I/O Config (8) setting would be “11111” for all of the above information to transfer between the module and the drive.

Step 5. Reset the mod ule. Refer to the s ection 4.4.3, Resetting

the Module, in this chapter.

The module 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 module. Re fer to chapter 5, Configuring the Interb us Sc an ner.

4.4 Settin g 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 Comm Flt Action (6).

ATTENTION:

the action of the module and connected SP600 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 hazard of injury or equipment damage. Failure to observe this precaution could result in bodily injury or damage to equipment.

Comm Flt Action (6) lets you determine

4.4.1 Changing the Fault Action

Set the value of Comm Flt Action (6) to the desired response as shown in table 4.4. See figure 4.3 for a sample LCD OIM Fault Action screen.
