MEMOBUS/Modbus Serial Communication
This section describes parameters necessary to set up MEMOBUS/Modbus communications.
n
H5-01: Drive Slave Address
Sets the drive slave address used for MEMOBUS/Modbus communications.
Note: Cycle the power after changing this parameter to enable the new setting.
No. Name Setting Range Default
H5-01 Drive Slave Address
0 to FFH
<1>
1FH
<1> If the address is set to 0, no response will be provided during communications.
Each slave drive must be assigned a unique slave address for serial communications to work. Setting H5-01 to any value
besides 0 assigns the drive its address in the network. Slave address do not need to be assigned in sequential order, but no two
drives may share the same address.
n
H5-02: Communication Speed Selection
Sets the MEMOBUS/Modbus communications speed.
Note: Cycle the power after changing this parameter to enable the new setting.
No. Name Setting Range Default
H5-02 Communication Speed Selection 0 to 5 3
H5-02 Communication Speed H5-02 Communication Speed
0 1200 bps 5 38400 bps
1 2400 bps 6 57600 bps
2 4800 bps 7 76800 bps
3 9600 bps 8 115200 bps
4 19200 bps
n
H5-03: Communication Parity Selection
Sets the parity used for MEMOBUS/Modbus communications.
Note: Cycle the power after changing this parameter to enable the new setting.
No. Name Setting Range Default
H5-03 Communication Parity Selection 0 to 2 0
Setting 0: No parity
Setting 1: Even parity
Setting 2: Odd parity
n
H5-04: Stopping Method after Communication Error
Selects the stopping method after a communications error (CE) has occurred.
No. Name Setting Range Default
