E.4 MEMOBUS/Modbus Setup Parametersu MEMOBUS/Modbus Serial CommunicationChanges to MEMOBUS/Modbus communications settings become effective after restarting the drive.n H5-01: Drive Slave AddressSets the drive slave address used for communications.Note: Cycle power for the setting to take effect.No. Name Setting Range DefaultH5-01 Drive Slave Address 0 to FFH 1FHEach slave drive must be assigned a unique slave address for serial communications to work. Slave addresses do not need tobe assigned in sequential order, but no two drives may share the same address.n H5-02: Communication Speed SelectionSets the communications speed for APOGEE FLN, BACnet, MEMOBUS/Modbus, and Metasys N2.Note: 1. Cycle power for the setting to take effect.2. When Metasys N2 communications are selected (H5-08 = 1), selecting a baud rate other than 9600 bps will trigger an oPE29 error.3. When APOGEE FLN (P1) communications are selected (H5-08 = 2), selecting a baud rate other than 4800 bps will trigger an oPE29error.4. When BACnet communications are selected (H5-08 = 3), selecting 115200 bps (Setting 8) will trigger an oPE29 error.No. Name Setting Range DefaultH5-02 Communication Speed Selection 0 to 8 <1><1> Default depends on H5-08 setting:H5-08 = 0, MEMOBUS/Modbus; default: 3H5-08 = 1, N2 (Metasys); default: 3H5-08 = 2, P1 (APOGEE FLN); default: 2H5-08 = 3, BACnet; default: 3H5-02 Communication Speed H5-02 Communication Speed0 <1> 1200 bps 5 <1> 38400 bps1 <1> 2400 bps 6 <1> 57600 bps2 4800 bps 7 <1> 76800 bps3 <1> 9600 bps 8 <1> <2> 115200 bps4 <1> 19200 bps<1> Not available when H5-08 is set to 2 P1 (APOGEE FLN).<2> Not available when H5-08 is set to 0 (MEMOBUS/Modbus) or 1 (Metasys N2).n H5-03: Communication Parity SelectionSets the parity used for communications.Note: Cycle power for the setting to take effect.No. Name Setting Range DefaultH5-03 Communication Parity Selection 0 to 2 0Setting 0: No paritySetting 1: Even paritySetting 2: Odd parityn H5-04: Stopping Method after Communication ErrorSelects the stopping method after a communications error (CE) has occurred.E.4 MEMOBUS/Modbus Setup ParametersYASKAWA SIEP YAIZ1U 03B YASKAWA AC Drive – Z1000 Programming Manual 307E MEMOBUS/ModbusCommunications
