3 : 4 to 20 mA
■ H4-08 AO2 Signal Level Select
No.
(Hex.)
Name Description
Default
(Range)
H4-08
(0424)
AO2 Signal Level Select
Sets the MFAO terminal AO2 output signal level.
1
(1 - 3)
Note:
Set jumper S5 on the terminal board to the correct position after changing this parameter.
1 : 0 to 10 Vdc
2 : -10 to +10 Vdc
3 : 4 to 20 mA
■ H4-20 An.Pwr Mon 100% Level
No.
(Hex.)
Name Description
Default
(Range)
H4-20
(0B53)
An.Pwr Mon 100% Level
Sets the level at 10 V when U1-08 [Output Power] is set for analog output.
0.00 kW
(0.00 - 650.00 kW)
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.
(Hex.)
Name Description
Default
(Range)
H5-01
(0425)
Mbus Address
Sets the communication slave address for drives.
1FH
(0 - FFH)
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.)
Name Description
Default
(Range)
H5-02
(0426)
Mbus BaudRate
Sets the communications speed for Modbus communications.
4
(1 - 9)
Note:
Restart the drive after you change the parameter setting.
1 : 1200 bps
2 : 2400 bps
3 : 4800 bps
4 : 9600 bps
