    Configuring the Adapter Setting a Fault Action By default, when communications are disrupted (for example, a cable is disconnected) or the master is idle, 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 10 - [Comm Flt Action] and a different response to an idle scanner using Parameter 11 - [Idle Flt Action].

  • Page 31: Resetting The Adapter

    Configuring the Adapter To set the fault configuration parameters If you set Parameter 10 - [Comm Flt Action], or 11 - [Idle Flt Action] to the “Send Flt Cfg,” the values in the following parameters are sent to the drive after a communications fault and/or idle fault occurs. You must set these parameters to values required by your application.

    A controller consists of a central processor, input/output interface, and memory. See also Scanner. ControlFLASH 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.
  • Page 148 DriveExplorer Software DriveExplorer software is a tool for monitoring and configuring Allen-Bradley products and adapters. It can be run on computers running Microsoft Windows 95, Windows 98, ME, Windows NT (version 4.0 or 2000), and Windows CE (version 2.01 or higher) operating systems.
  • Page 149 Glossary-3 occurs or when the scanner is switched out of run mode. The former uses a communications fault action, and the latter uses an idle fault action. Fault Configuration When communications are disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond with a user-defined fault configuration.
  • Page 150 PowerFlex Drives The Allen-Bradley PowerFlex family of drives includes PowerFlex 70, PowerFlex 700, and PowerFlex 7000 drives. These drives can be used for applications ranging from 0.37 kW (0.5 HP) to 3,000 kW (4,000 HP).
  • Page 151 Glossary-5 Reference/Feedback The Reference is used to send a Reference (for example, speed, frequency, torque) to the product. It consists of one word of input 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.
