H4-07 Terminal AM Signal Level
Select
(0423)
Note:
Set jumper S5 on the control circuit terminal block accordingly when changing these parameters.
0 : 0-10V
2 : 4 to 20 mA

H4-20: Analog Power Monitor 100% Level
No.
Name
(Hex.)
H4-20 Analog Power Monitor
100% Level
(0B53)
Note:
• When H4-20 = 0.00 kW, the output power monitor 10 V level = motor rated power (kW). The setting changes when the A1-02 [Control
Method Selection] value changes:
–A1-02 = 0 [V/f]: E2-11 [Motor Rated Power]
–A1-02 = 2 [OLV]: E2-11 [Motor Rated Power]
–A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E5-02 [PM Motor Rated Power]
–A1-02 = 8 [EZOLV]: E9-07 [Motor Rated Power]

H5: Memobus/Modbus Communication

H5 parametersconfigure 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:
• 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.

H5-02: Communication Speed Selection
No.

Note:
Re-energize the drive or set H5-20 = 1 [Communication Parameters Reload = Reload Now] after you change the parameter setting.
