■ H4-20: Analog Power Monitor 100% Level
No.
(Hex.)
Name Description
Default
(Range)
H4-20
(0B53)
Analog Power
Monitor 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 Selection]
setting sets the motor rated power:
–A1-02 = 0, 1 [V/f Control, V/f Control with Encoder]: E2-11 [Motor Rated Power (kW)]
–A1-02 = 2, 3, 4 [Open Loop Vector, Closed Loop Vector, Advanced Open Loop Vector]: E2-11 [Motor Rated Power (kW)]
–A1-02 = 5, 6, 7 [PM Open Loop Vector, PM Advanced Open Loop Vector, PM Closed Loop Vector]: E5-02 [PM Motor Rated Power
(kW)]
–A1-02 = 8 [EZ Vector Control]: E9-07 [Motor Rated Power (kW)]
◆ 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.
(Hex.)
Name Description
Default
(Range)
H5-01
(0425)
Drive Node 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 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 slave address that is different from other slave devices.
■ H5-02: Communication Speed Selection
No.
(Hex.)
Name Description

Speed Selection
Sets the communications speed for MEMOBUS/Modbus communications.
