F.2 Connecting to a NetworkThis section explains how to connect the drive to an N2 network and the network termination required for a connection.u Network Cable ConnectionFollow the instructions below to connect the bypass to a N2 network.1. With the power shut off, connect the communications cable to the bypass controller and the master. Use terminal TB3for N2.TB34321SHLDTXRX-TXRX+IG5ShieldTransmit/Receive (-)Transmit/Receive (+)Isolated Ground ReferenceFigure F.2 Serial Communications Cable Connection Terminal (TB3)Note: Separate the communications cables from the main circuit cables and other wiring and power cables. Use shielded cables forthe communications cables, and properly shielded clamps to prevent problems caused by electrical interference.2. Check or set the termination resistor selection at all slaves. Refer to the description in the Network Terminationsection for details on the termination resistor.3. Switch the power on.4. Set the parameters needed for serial communications (Z3-01 through Z3-11) using the digital operator.5. Shut the power off and wait until the display on the digital operator goes out completely.6. Turn the power back on.7. The bypass is now ready to begin communicating with the master.F.2 Connecting to a NetworkYASKAWA ELECTRIC SIEP YAIZ1B 01E YASKAWA AC Drive – Z1000 Bypass Technical Manual 425F Metasys N2 NetworkProtocol
