Important: If the Data Rate switch is set to “PGM” (Program), the module will use the setting of DF1 Addr Cfg (module parameter 3) for the node address. The default setting of this parameter is 1. Refer to chapter 4, Configuring the RS485 DF1 Module, for more information. Figure 3.1 – Setting the Module’s Node Address Step 2.
3.3 Connecting the Module to the Drive ATTENTION: The SP600 drive may contain high voltages that can cause injury or death. Remove power from the drive, and then verify power has been discharged before installing or removing a module. Failure to observe this precaution could result in severe bodily injury or loss of life. ! Step 1. Remove power from the drive. Step 2. Use static control precautions. Step 3.

3.4 Connecting the Module to the Network ATTENTION: The SP600 drive may contain high voltages that can cause injury or death. Remove power from the drive, and then verify power has been discharged before installing or removing a module. Failure to observe this precaution could result in severe bodily injury or loss of life. ! Step 1. Remove power from the drive. Step 2. Use static control precautions. Step 3. Connect an RS485 cable to the network, and route it through the bottom of the drive.
3.5 Applying Power ! ATTENTION: Unpredictable operation may occur if parameter settings and switch settings are not compatible with your application. Verify that settings are compatible with your application before applying power to the drive. Failure to observe these precautions could result in severe bodily injury of loss of life. Step 1. Close the door or reinstall the cover on the drive. The status indicators can be viewed on the front of the drive after power has been applied. Step 2.

CHAPTER 4 Configuring the RS485 DF1 Module Chapter 4 provides instructions and information for setting the parameters in the module. For a complete list of parameters, refer to Appendix B, RS485 DF1 Module Parameters. For definitions of terms in this chapter, refer to the Glossary. 4.1 Configuration Tools The module stores parameters and other information in its own nonvolatile memory. Therefore, you must access the module to view and edit its parameters. Table 4.
4.2 Using the LCD OIM to Configure the Module Use the procedure in figure 4.1 to access the parameters on the RS485 DF1 module using the LCD OIM. If you are unfamiliar with the operation of the LCD OIM, refer to the SP600 AC Drive User Manual (D2-3485 or D2-3501) for more information.
4.4 Setting the Data Rate If the Data Rate switch on the module is set to “PGM,” the value of module parameter 5 (DF1 Rate Cfg) determines the RS485 DF1 data rate. Your application may require a different setting. Step 1. Set the value of module parameter 5 (DF1 Rate Cfg) to the data rate at which your network is operating. Refer to figure 4.3. Port 5 Device RECOMM-485 Parameter #: 5 DF1 Rate Cfg 3 9600 bps Value 0 1 2 3 4 5 Baud Rate 1200 bps 2400 bps 4800 bps 9600 bps (default) 19.2 kbps 38.
4.6 Setting the I/O Configuration The I/O configuration determines the type of data sent to the drive. This is a two-part process: enabling/disabling the data transmitted between the module and the drive, and identifying the data transmitted between the module and the master (i.e., scanner). Step 1. Enable or disable the data transmitted between the module and the drive by setting the bits in module parameter 12 (DPI I/O Config). A “1” enables the I/O. A “0” disables the I/O. Bit 0 is the right-most bit.
4.7 Setting a Fault Action By default, when communications are disrupted (for example, a cable is disconnected) or the scanner 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 module parameter 10 (Comm Flt Action). ! ATTENTION: Module parameter 10 (Comm Flt Action) lets you determine the action of the module and connected drive if communications are disrupted. By default, this parameter faults the drive.
4.7.1 Setting the Fault Configuration Parameters If you set module parameter 10 (Comm Flt Action) to “Send Flt Cfg,” the values in the parameters shown in table 4.3 are sent to the drive after a communications fault occurs. You must set these parameters to values required by your application. Table 4.3 – Fault Configuration Parameters Parameter Number Name Description 14 Flt Cfg Logic A 16-bit value sent to the drive for Logic Command.
Set module parameter 9 (Reset Module) to “Reset Module.” See figure 4.7. Port 5 Device RECOMM-485 Parameter #: 9 Reset Module 1 Reset Module Value 0 1 2 Description Ready (default) Reset Module Set Defaults Figure 4.7 – Reset Screen on an LCD OIM When you enter 1 (“Reset Module”) the module is immediately reset. When you enter 2 (“Set Defaults”) the module sets all module parameters to their factory-default settings. The module should be reset after performing a “Set Defaults.
4.8 Viewing the Module Configuration The parameters in table 4.4 provide information about how the module is configured. You can view these parameters at any time. Table 4.4 – Module Configuration Status Parameters No. Name 01 DPI Port 02 DPI Data Rate 04 DF1 Addr Actual 06 DF1 Rate Actual 07 Ref/Fdbk Size 08 Datalink Size 11 Active Cfg 13 DPI I/O Active 25 26 CRC/BCC Act Dup Msg Detect 4-8 Description The port to which the module is connected. This will usually be port 5.
CHAPTER 5 Using VS Utilities on the RS485 Network Chapter 5 provides instructions for configuring VS Utilities (version 1.01 or higher) to access SP600 drives on the RS485 network. Figure 5.1 shows a typical RS485 DF1 network. PC Running VS Utilities RECOMM-232 Serial Converter Module SP600 Drives Figure 5.1 – Typical RS485 DF1 Network To connect to the network using VS Utilities: Step 1. Select Explore > Connect > Network as shown in figure 5.2. VS Utilities Figure 5.
Step 2. Select Single to connect to a single node on the network.

GLOSSARY BCC (Block Check Character) - A technique for error detection in data communications. A character is added to a transmission block, which is compared with a second BCC computer by the receiver to determine if the transmission is error free. controller - Also called programmable logic controller.
DPI product - A device that uses the DPI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a SP600 drive is a DPI product. In this manual, a DPI product is also referred to as “product” or “host.” fault action - Determines how the module and connected product act when a communications fault (for example, a cable is disconnected) occurs or when the scanner is switched out of run mode.
module - Devices such as drives, controllers, and computers usually require a module to provide a communication interface between them and a network such as RS485 DF1. An module 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 RS485 DF1 module connects SP600 drives to an RS485 DF1 network. Modules are sometimes also called “adapters,” “cards,” “embedded communication options,” “gateways,” and “peripherals.
Type 0/Type 1/Type 2 Control - When transmitting I/O, the module can use different types of messages for control. The Type 0, Type 1, Type 2 control events help Reliance Electric personnel identify the type of message that a module is using. transaction number (TNS) - A two-byte field in a DF1 message packet that is used in combination with the SRC (source node of the message) and CMD (command code) bytes to uniquely identify every message packet.
