Chapter 3 Configuring the Adapter This chapter provides instructions and information for setting the parameters to configure the adapter.
3-2 Configuring the Adapter Using the PowerFlex 7-Class If your drive has either an LED or LCD HIM (Human Interface Module), it can be used to access parameters in the adapter as shown below. We HIM to Access Parameters recommend that you read through the steps for your HIM before performing the sequence. For additional information, see the drive documentation or the PowerFlex 7-Class HIM Quick Reference, publication 20HIM-QR001. Using an LED HIM Step Example Screens 1.
Configuring the Adapter Setting the I/O Configuration 3-3 The I/O configuration determines the data that is sent to and from the drive. Logic Command/Status, Reference/Feedback, and Datalinks may be enabled or disabled. (Datalinks allow you to read/write directly to parameters in the drive using implicit I/O.) A ‘1’ enables the I/O and a ‘0’ disables the I/O. 1. Set the bits in Parameter 9 - [DPI I/O Cfg].
3-4 Configuring the Adapter Setting a Communication Fault Action By default, when I/O communication is 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 the disrupted I/O communication by using Parameter 6 - [Comm Flt Action]. The drive will remain in its present state (for example, a running drive will continue to run) until the value in Parameter 7 - [RcvHrtBeat Time] has elapsed.
Configuring the Adapter Port 5 Device 20-COMM-L Parameter #: 07 RcvHrtBeat Time 120.0 s 0 <> 3276.7 3-5 Default = 120.0 s Changes to these parameters take effect immediately. A reset is not required. Setting the Fault Configuration Parameters When setting Parameter 6 - [Comm Flt Action] or 8 - [Idle Flt Action] to ‘Send Flt Cfg’, the values in the following parameters are sent to the drive after an I/O communication fault and/or idle fault occurs.
3-6 Configuring the Adapter Setting the Fault Configuration Parameters See Setting the Fault Configuration Parameters on page 3-5 for details, which apply to both Parameter 6 - [Comm Flt Action] and Parameter 8 [Idle Flt Action]. Resetting the Adapter Changes to some adapter parameters require that you reset the adapter before the new settings take effect. You can reset the adapter by power cycling the drive or by using Parameter 5 - [Reset Module].
Configuring the Adapter Updating the Adapter Firmware 3-7 The adapter firmware can be updated over the network or serially through a direct connection from a computer to the drive using a 1203-USB or 1203-SSS serial converter.

Chapter 4 Configuring the LonWorks Network This chapter provides information about configuring network variables to access a PowerFlex 7-Class drive over a LonWorks network.
4-2 Configuring the LonWorks Network Operating the Drive Using a A LonMark profile defines the functional profile for a node communicating with other nodes. The profile specifies which SNVTs (Standard Network LonMark Profile Variable Types) and SCPTs (Standard Configuration Property Types) are used, and provides a semantic meaning about the information being communicated. When a profile is implemented in a node, it is called a LonMark object. One node can have several objects implemented.
Configuring the LonWorks Network Figure 4.
4-4 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 status indicator flashes to indicate that a WINK was received. This LED flashes red according to the following sequence: • 3 fast flashes • OFF for 1 second This sequence is repeated 10 times.
Configuring the LonWorks Network Network Variable Inputs (NVIs) 4-5 This section provides descriptions of the Network Variable Inputs. Node Object Request Variable: nviObjRequest Format: SNVT_obj_request Explanation: This input enables control commands and updates from the network to specific objects in the node. The identification number for the node is 0 and for the drive object is 1. The request functionality is the same for both objects.
4-6 Configuring the LonWorks Network Drive Speed Setpoint Variable: nviDrvSpeedStpt Format: SNVT_switch Explanation: This network variable input provides a speed reference setpoint. When nviDrvSpeedStpt.state is set to zero, the drive is stopped. Valid Range: State Value Requested Speed 0 n/a STOPPED 1 0% 0% 1 0.5…100.0% 0.5…100.0% 1 100.0% 100.0% 0xFF n/a AUTO (Default) Default Value: Default value is AUTO (state = 0xFF). This value is adapted at power up.
Configuring the LonWorks Network 4-7 Module Configuration Variable: nviNV_config Format: UNVT_DPI_CONFIG Explanation: This network variable input provides information on how parameters should be mapped to network variables. The NVI contains two fields: • NV_index • DPI_parameter To check an already existing configuration, use the following procedures: A. To check which DPI parameter a network variable is connected to, use nviNV_config with the following data: UNVT_DPI_CONF.
4-8 Configuring the LonWorks Network Default Value: This configuration is the default for PowerFlex 70/700 drives. For other drives, the defaults are 0 and need to be configured prior to network commissioning. A value of 0 means the variable is disabled and cannot be used to send/receive data. Note: It is necessary to configure nciNmlFreq and nciMaxSpeed to operate the drive from the network.
Configuring the LonWorks Network Network Variable Outputs (NVOs) 4-9 This section describes the network variable outputs. No output values are sent over the network, unless they have changed (except nvoDrvSpeed, which is sent for the heartbeat functionality, and nvoObjStatus, if update status is requested).
4-10 Configuring the LonWorks Network Drive Speed Variable: nvoDrvSpeed Format: SNVT_level_percent Explanation: This network variable output provides the speed of the drive as a percentage of the nominal speed. This network variable output is also used as a heartbeat to monitor the health of the LonWorks communication interface. Default PowerFlex 70/700 Drive Parameter Mapping: Parameter 1 - [Output Freq] This can be mapped using the nviNV_config variable.
Configuring the LonWorks Network 4-11 Output Frequency Variable: nvoDrvFreqAct Format: SNVT_freq_hz Explanation: This network variable output provides the drive output frequency in Hz. This value is always positive. It does not indicate the forward/reverse direction of motor revolution. Default PowerFlex 70/700 Drive Parameter Mapping: Parameter 1 - [Output Freq] This can be mapped using the nviNV_config variable or adapter Parameter 28 - [DrvFreqActParam].
4-12 Configuring the LonWorks Network Datalink Outs Variable: nvoDatalinkA1 nvoDatalinkA2 nvoDatalinkB1 nvoDatalinkB2 nvoDatalinkC1 nvoDatalinkC2 nvoDatalinkD1 nvoDatalinkD2 Format: UNVT_DATALINK Explanation: These network variable outputs are used for generic parameter inputs by way of Datalink Outs. To set up a Datalink, configure the adapter according to the drive manual. All data is sent in raw format; that is, no scaling is performed.
Configuring the LonWorks Network Network Configuration Inputs (NCIs) 4-13 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.
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 can help to limit the use of bandwidth on the LonWorks network. Setting nciMinOutTm to ‘0’ disables transmission limiting. Valid Range: 0.0…6553.4 seconds. Default Value: 0.
Configuring the LonWorks Network 4-15 Minimal Speed NCI: nciMinSpeed Format: SNVT_lev_percent Explanation: This network configuration input specifies the minimum speed of the motor. Its value is entered as a percentage of nominal frequency as defined by the Nominal frequency (nciNmlFreq) configuration value. For example, if nciNmlFreq = 50 Hz. and nciMinSpeed = 10%, the minimum speed is 5 Hz. Valid Range: The minimum speed value must be validated as follows: -163.84% ≤ minimum speed ≤ maximum speed ≤ 163.
4-16 Configuring the LonWorks Network Ramp Up Time NCI: nciRampUpTm Format: SNVT_time_sec Explanation: This network configuration input sets the acceleration time. The value specifies the length of time it will take to bring the inverter from stop to maximum frequency. Default Value: 10.0 seconds Default PowerFlex 70/700 Drive Parameter Mapping: Parameter 140 - [Accel Time] This can be adjusted using the nviNV_config variable or adapter Parameter 33 - [RampUpTmParam].
Configuring the LonWorks Network 4-17 Generic Parameter Read Address NCI: nciParRdAdr Format: SNVT_count Explanation: This network configuration input is used to read any parameter in the drive. The data is read via the nvoGenData output. Default Value: 0 (Not used) Valid Range: Any valid drive parameter. Generic Parameter Write Address NCI: nciParWriAdr Format: SNVT_count Explanation: This network configuration input is used to set the parameter number to which a write operation is to be performed.
4-18 Configuring the LonWorks Network Conditions Required for Operation This section describes 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.
Configuring the LonWorks Network 4-19 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. The adapter response to loss of communication depends on the setting of adapter Parameter 6 - [Comm Flt Action]. See Chapter 5, Troubleshooting for more information on potential problems with the adapter and network.

Glossary A Adapter Devices such as drives, controllers, and computers usually require a network communication adapter to provide a communication interface between them and a network such as LonWorks. An adapter reads data on the network and transmits it to the connected device. It also reads data in the device and transmits it to the network. The 20-COMM-L LonWorks adapter connects PowerFlex 7-Class drives to a LonWorks network.
G-2 Glossary D Data Rate The speed at which data is transferred on the network. Each device on the network must be set for the same data rate. Datalinks A Datalink is a type of pointer used by PowerFlex 7-Class drives to transfer data to and from the controller. Datalinks enable specified parameters to be read or written to without using explicit messages. The drive determines the size of Datalinks.
Glossary F G-3 Fault Action A fault action determines how the adapter and connected drive act when a communication fault (for example, a cable is disconnected) occurs. Fault Configuration When communication is disrupted (for example, a cable is disconnected), the adapter and connected drive can respond with a user-defined fault configuration. The user sets the data that is sent to the drive using specific fault configuration parameters in the adapter.
G-4 Glossary LON™ An acronym for local operating network. Consists of intelligent devices, or nodes, that are connected by one or more communications media and that communicate with one another using a common protocol. LonMaker™ Software Windows™-based software package for designing, documenting, installing, and maintaining multi-vendor, open, interoperable LonWorks networks. LonWorks™ Device Hardware and software than runs an application and communicates with other devices using the LonWorks protocol.
Glossary P G-5 Ping A message that is sent by a DPI product to its peripheral devices. They use the ping to gather data about the product, including whether it can receive messages and whether they can log in for control. PowerFlex 7-Class (Architecture Class) Drives The Allen-Bradley PowerFlex 7-Class family of drives supports DPI and, at the time of publication, includes the PowerFlex 70, PowerFlex 700, PowerFlex 700H, PowerFlex 700S, PowerFlex 700L, and PowerFlex 7000.
