Note:
Make sure that you also set jumper S5 on the control circuit terminal block when you change this parameter.

100% Level
(0B53)
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 [V/f]: E2-11 [Motor Rated Power]
–A1-02 = 5 [OLV/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).
■
H5-01: Drive Node Address
No.
Name
(Hex.)
H5-01 Drive Node Address
(0425)
Note:
• Restart the drive after you change the parameter setting.
• Setting 0 will not let the drive respond to MEMOBUS/Modbus communications.
• When Y1-01 = 3 [Multiplex Mode = Memobus Network], the setting range changes when the Y9-25 [Highest Node Address] setting
changes.
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 slave address that is different from other slave devices.
