F.3 N2 Setup Parameters
u N2 Serial Communication
This section describes parameters necessary to set up N2 communications.
n Z3-01: Serial Communications Protocol Select
Selects the communications protocol.
No. Name Setting Range Default
Z3-01 Serial Communications Protocol Selection 0 to 3 0
Setting 0: MEMOBUS/Modbus
Setting 1: N2
Setting 2: P1
Setting 3: BACnet
n Z3-02: Serial Communications Node Address Select
Sets the drive slave address used for communications.
Note: Cycle the power after changing this parameter to enable the new setting.
No. Name Setting Range Default
Z3-02 Serial Communications Node Address Select 0 to FFH 1FH
Each slave drive must be assigned a unique slave address for serial communications to work. Slave addresses do not need to
be assigned in sequential order, but no two drives may share the same address.
n Z3-03: Serial Communications Baud Rate Select
Selects the bypass serial communications speed.
No. Name Setting Range Default
Z3-03 Serial Communications Baud Rate Select 0 to 8 3
Setting 0: 1200 bps
Setting 1: 2400 bps
Setting 2: 4800 bps
Setting 3: 9600 bps
Setting 4: 19200 bps
Setting 5: 38400 bps
Setting 6: 57600 bps
Setting 7: 76800 bps
Setting 8: 115200 bps
n Z3-04: Serial Communications Parity Select
Sets the parity used for communications.
Note: Cycle the power after changing this parameter to enable the new setting.
No. Name Setting Range Default
Z3-04 Serial Communications Parity Select 0 to 2 0
Setting 0: No parity
Setting 1: Even parity
Setting 2: Odd parity
n Z3-05: Serial Communications Fault Select
Selects the action to take when a serial communications fault is detected. A serial communications fault is detected when after
last communicating, no communications occurs within the time set to Z3-06.
