H4-20 An.Pwr Mon 100% Level
(0B53)
Note:
• When H4-20 = 0.00 kW, the output power monitor 10 V level = motor rated power (kW). The A1-02 [Control Method] setting sets the
motor rated power:
–A1-02 = 0, 1 [V/f Control, PG V/f Control]: E2-11 [Motor Rated Power (kW)]
–A1-02 = 2, 3, 4 [OLVector, CLVector, Adv OLVector]: E2-11 [Motor Rated Power (kW)]
–A1-02 = 5, 6, 7 [PM OLVector, PM AOLVector, PM CLVector]: E5-02 [PM Mot Rated Power (kW)]
–A1-02 = 8 [EZ Vector]: E9-07 [Motor Rated Power (kW)]

H5: MODBUS PORTS

H5 parameters configure the drive to use Modbus communications.
You can use the Modbus protocol over the RS-485 port (terminals RS485+ and RS485-) in the drive to use serial
communication with programmable controllers (PLC).

H5-01 Mbus Address
No.
Name
(Hex.)
H5-01 Mbus Address
(0425)
Note:
• Restart the drive after changing the parameter setting.
• Setting 0 will not let the drive respond to Modbus communications.
To enable the drive to communicate with the controller (master) over 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.

H5-02 Mbus BaudRate
No.

(Hex.)
H5-02 Mbus BaudRate

Note:
Restart the drive after you change the parameter setting.
1 : 1200 bps
2 : 2400 bps
3 : 4800 bps
4 : 9600 bps
