5 Installation Procedure14 YASKAWA ELECTRIC SIEP C730600 42B 1000-Series Option SI-P3 Technical Manual5. Select the proper type of 9-pin D-sub CN5 connector and network cable.Refer to on page 41 for details on cable selections and cable lengths.Refer to the PROFIBUS-DP website at www.profibus.com for more information on cables and connectors.6. Connect the option to the network using a 9 pin D-sub connector as shown in Figure 7.Connection DiagramFigure 7Figure 7 Option Connection Diagram<1> The ground wire provided in the option shipping package must be connected during installation.PROFIBUS-DP TerminationThe option does not have a termination resistor. The termination resistance must be set on the final drive in thenetwork using a switch on the 9-pin D-sub connector. Make sure that only the connector for the final drive in thenetwork has a termination resistor; communication problems may arise if any other network drive has atermination resistor.Use only the input side cable entry as shown in Figure 8 when connecting both ends of the network. Most 9-pinD-sub connectors have a function for disconnecting the output side of the cable. Communication will not bepossible between devices if the connector is reversed. Most connectors have arrows indicating the input andoutput sides.Figure 8Figure 8 PROFIBUS Cable Connection with Termination ResistorsBus termination ON = incoming and outgoing cables not connected.Bus termination OFF = incoming and outgoing cables connected.Drive9-pin D-sub ConnectorFor the last node on the bus,turn on the termination resistor switch.SI-P3RTSDGNDVPA-lineB-line1B1A384652B2ACN5-AFE<1>PROFIBUS Cable PROFIBUS Cable Connector(Red)(Green)(Red)(Green)(Shell)To PROFIBUS-DPMasterTo the next slave(Shell)ONOFFOutgoing CableIncoming CableSwitchBus termination9-pin D-sub ConnectorOOO
