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.
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.
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.
Setting 0: No parity
Setting 1: Even parity
Setting 2: Odd parity
H5-04: Stopping Method after Communication Error
