H5: Memobus/Modbus Communication - YASKAWA GA700 Series Technical Manual

12.8 H: Terminal Functions
Note:
• When H4-20 = 0.00 kW, the output power monitor 10 V level = motor rated power. The setting changes when the A1-02 [Control
Method Selection] value changes:
–A1-02 = 0, 1 [V/f, CL-V/f]: E2-11 [Motor Rated Power]
–A1-02 = 2, 3, 4 [OLV, CLV, AOLV]: E2-11 [Motor Rated Power]
–A1-02 = 5, 6, 7 [OLV/PM, AOLV/PM, CLV/PM]: E5-02 [PM Motor Rated Power]
–A1-02 = 8 [EZOLV]: E9-07 [Motor Rated Power]

H5: Memobus/Modbus Communication

H5 parameters configure the drive to use MEMOBUS/Modbus communications.
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).

(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.
