H5: MEMOBUS/Modbus Serial Communication

Serial communication is possible in the drive using the built-in RS-422/485 port (terminals R+, R-, S+, S-) and programmable
logic controllers (PLCs) or similar devices running the MEMOBUS/Modbus protocol.
The H5-ooparameters set the drive for MEMOBUS/Modbus Communications.
n H5-01: Drive Slave Address
Sets the drive slave address used for communications.
Note: Cycle the power after changing this parameter to enable the new setting.
No.
H5-01
<1> If the address is set to 0, no response will be provided during communications.
