C.4 MEMOBUS/Modbus Setup Parameters
 MEMOBUS/Modbus Serial Communication
The settings for MEMOBUS/Modbus communications become effective when the drive is restarted after they have been
made.
H5-01: Drive Slave Address

Sets the drive slave address used for MEMOBUS/Modbus communications.
Note: After changing this parameter, the power must be cycled to enable the new setting.
No.
H5-01
<1> If the address is set to 0, no response will be provided during communications.
For serial communications to work, each individual slave drive must be assigned a unique slave address. Setting H5-01
to any value besides 0 assigns the drive its address in the network. Slave address don't need to be assigned in sequential
order, but each address needs to be unique so that no two drives have the same address.
H5-02: Communication Speed Selection

Sets the MEMOBUS/Modbus communications speed.
Note: After changing this parameter, the power must be cycled to enable the new setting.
No.
H5-02
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
H5-03: Communication Parity Selection

Sets the parity used for MEMOBUS/Modbus communications.
Note: After changing this parameter, the power must be cycled to enable the new setting.
No.
H5-03
Setting 0: No parity
Setting 1: Even parity
Setting 2: Odd parity
H5-04: Stopping Method after Communication Error

Selects the stopping method after a MEMOBUS/Modbus communications error (CE) has occurred.
