Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. “Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls” (Publication SGI-1.1) describes some important differences between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.

Configuring the Adapter Using the PowerFlex HIM If your drive has either an LED or LCD HIM (Human Interface Module), access parameters in the adapter as follows: Using an LED HIM Step Key(s) Example Screens 1. Press the ALT key and then the Device Sel (Device) key to display the Device Screen.
Configuring the Adapter Setting the I/O Configuration The I/O configuration determines the type of data sent to the drive. Logic Command/Status and Datalinks may be enabled or disabled. 1. Set the bits in Parameter 9 - [DPI I/O Cfg]. A “1” enables the I/O.
Configuring the Adapter Setting the Comm Fault Action By default, when communications are disrupted (for example, a cable is disconnected), the drive will remain in its current state (e.g. a running drive will continue to run) until Parameter 7 - [RcvHrtBeat Time] has elapsed.
Configuring the Adapter • Setting Parameter 7 - [RcvHrtBeat Time] to “0” disables the fault action, and a value greater than “0” enables the fault action. If nviDrvSpeedStpt is not received by the adapter within the Parameter 7 - [RcvHrtBeat Time] value, the fault action in Parameter 6 - [Comm Flt Action] will be taken.
Configuring the Adapter To set the fault configuration parameters If you set Parameter 6 - [Comm Flt Action] or Parameter 8 - [Idle Flt Action] to “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.

Configuring the LonWorks Network Operating the Drive Using a LonMark Profile A LonMark profile defines the functional profile for a node communicating with other nodes. The profile specifies which SNVTs (Standard Network Variable Types) and SCPTs (Standard Configuration Property Types) are used, and provides a semantic meaning about the information being communicated.
Configuring the LonWorks Network Node Operations The following sections describe the basics of node operation. WINK (What is a WINK?) WINK is a network command that verifies communication with a node. The NET A indicator will flash to indicate that a WINK was received.

Configuring the LonWorks Network 4-13 Network Configuration Inputs (NCIs) The values of the NCIs change when written to and keep their values after a power cycle. All NCIs, with a corresponding parameter in the drive, are read from the drive after reset and when going from offline to online. When the parameter is updated from the network, it is written to the drive.
Page 42
4-14 Configuring the LonWorks Network Minimum Send Time NCI: nciMinOutTm Format: SNVT_time_sec Explanation: This network configuration input specifies the minimum period of time that expires before the network variable outputs can be re-sent. All variables are updated if they changed at each period end. This is good for limiting use of bandwidth on the LonWorks network.

Configuring the LonWorks Network 4-19 Conditions Required for Operation This section will describe what conditions are required for performing some common actions and how the combination of SNVTs and SCPTs affects the operation of the drive. Starting the Drive The drive will RUN if nviDrvSpeedStpt.state is TRUE. Stopping the Drive The drive stops using the default stop mode if NviSpeedStpt.state is set to zero or if the node is brought offline or disabled, depending on the...
4-20 Configuring the LonWorks Network nciMinOutTm vs. nciSendHrtBt The nciMinOutTm has priority over nciSendHrtBt. This means that heartbeats will not be sent as often as specified in nciSendHrtBt if nciMinOutTm has a longer time set. Error Handling If nciRcvHrtBt is larger than zero, and heartbeats are not received within the nciRcvHrtBt time, then communication with the LonWorks network is considered down.

Glossary Flash Update The process of updating firmware in the adapter. The adapter can be flash updated using the X-Modem protocol or Control FLASH, and a serial converter. Hold Last When communications are disrupted (for example, a cable is disconnected), the adapter and drive can respond by holding last. Hold last results in the drive receiving the last data received via the network connection before the disruption.
Page 74
Glossary LonWorks Network Intelligent devices that communicate with each other using the LonWorks protocol over one or more communications channels. LonWorks Protocol The open control networking protocol designed for applications involving sense, monitor, control, and identification functions. Also known as EIA 709.1 Control Networking Standard and as LonTalk protocol.
Page 75
Glossary Protocols Rules that order how information is transmitted and presented. An “open protocol” is one in which the manufacturer has made the language “translation” available to anyone who wishes to use it. Reference/Feedback The Reference is used to send a reference (for example, speed, frequency, torque) to the product.
Page 76
Glossary Zero Data When communications are disrupted (for example, a cable is disconnected), the adapter and drive can respond with zero data. Zero data results in the drive receiving zero as values for command data. If the drive was running and using the reference from the adapter, it will stay running but at zero reference.
