12.8 H: Terminal Functions
You can use the MEMOBUS/Modbus protocol over the RS-485 port (terminals D+ and D-) in the drive to use serial
communication with programmable controllers (PLC).

H5-01: Drive Node Address
No.
Name
(Hex.)
H5-01 Drive Node Address
(0425)
Note:
• Re-energize the drive or set H5-20 = 1 [Communication Parameters Reload = Reload Now] after you change the parameter setting.
• Setting 0 will not let the drive respond to MEMOBUS/Modbus communications.
To enable the drive to communicate with the controller (master) over MEMOBUS/Modbus communications, you
must set the drive with a slave address. Set H5-01 ≠ 0.
Set a node address that is different from the master and other slave devices.
