C.4 BACnet Setup Parametersu BACnet Serial CommunicationThis section describes parameters necessary to set up BACnet communications.n Z3-01: Serial Communications Protocol SelectSelects the bypass serial communications protocol.No. Name Setting Range DefaultZ3-01 Serial Communications Protocol Select 0 to 3 3Setting 0: ModbusSetting 1: N2Setting 2: P1Setting 3: BACnetn Z3-02: Serial Communications Node SelectSelects the bypass serial communications node address.Note: Each slave must be assigned a unique slave address for serial communications to work properly. Slave addresses do not need to be assignedin sequential order, but no two slaves may share the same address.No. Name Setting Range DefaultZ3-02 Serial Communications Node Select 0 to 127 1n Z3-03: Serial Communications Baud Rate SelectSelects the bypass serial communications speed.Selecting settings 0, 1, or 2 will trigger an oPE29 error when using BACNet communication (Z3-01 = 3) in bypass controllersoftware versions VST800400 and later.No. Name Setting Range DefaultZ3-03 Serial Communications Baud Rate Select 0 to 8 3Setting 0: 1200 bpsSetting 1: 2400 bpsSetting 2: 4800 bpsSetting 3: 9600 bpsSetting 4: 19200 bpsSetting 5: 38400 bpsSetting 6: 57600 bpsSetting 7: 76800 bpsSetting 8: 115200 bpsn Z3-05: Serial Communications Fault SelectSelects the action to take when a serial communications fault is detected. A serial communications fault is detected when afterlast communicating, no communications occurs within the time set to Z3-06.No. Name Setting Range DefaultZ3-05 Serial Communications Fault Select 0 to 4 1Setting 0: IgnoreSetting 1: Alarm OnlySetting 2: Fault with EF0An EF0 fault will be sent to the drive.Setting 3: Fault with EF0 and Open ContactorsAn EF0 fault will be sent to the drive and the bypass contactor (K3) will be opened.C.4 BACnet Setup Parameters364 YASKAWA ELECTRIC SIEP YAIZ1B 01E YASKAWA AC Drive – Z1000 Bypass Technical Manual
