H4-07: MFAO Term FM Signal Level Select
No.
Name
(Hex.)
H4-07 Terminal FM Signal
Level Select
(0423)
Note:
Set jumper S5 on the control circuit terminal block accordingly when changing these parameters.
0 : 0-10 VDC
1 : -10 +10 VDC
2 : 4-20 mA
■
H4-08: MFAO Term AM Signal Level Select
No.
Name
(Hex.)
H4-08 Terminal AM Signal
Level Select
(0424)
Note:
Set jumper S5 on the control circuit terminal block accordingly when changing these parameters.
0 : 0-10 VDC
1 : -10 +10 VDC
2 : 4-20 mA

H4-20: Output Power Monitor Level
No.
Name
(Hex.)
H4-20 Output power
monitor level
(0B53)
Note:
• When H4-20 = 0.00 kW, the output power monitor 10 V level = motor rated power (kW). It is determined by the A1-02 [Control
Method Selection] setting.
–A1-02 = 0, 1 [V/f Control, Closed Loop V/f Control]: E2-11 [Motor Rated Power (kW)]
–A1-02 = 2, 3, 4 [Open Loop Vector Control, Closed Loop Vector Control, Advanced OpenLoop Vector Control]: E2-11 [Motor Rated
Power (kW)]
–A1-02 = 5, 6, 7 [PM Open Loop Vector Control, PM Advanced Open Loop Vector, PM Closed Loop Vector Control]: E5-02 [PM
Motor Rated Capacity]
–A1-02 = 8 [EZ Open Loop Vector Control]: E9-07 [Mtr Rated Power]

H5: Memobus/Modbus Communication

H5 parameters are used to configure the drive to use MEMOBUS/Modbus communications.
Serial communication with programmable controllers (PLC) can be performed using the MEMOBUS/Modbus
protocol over the RS-485 port (terminals D+ and D-) built into the drive.
■
H5-01: Drive Node Address
No.
Name
(Hex.)
H5-01 Drive Node Address
(0425)
Note:
• Restart the drive to enable the settings.
• Setting the parameter to 0 will cause the drive to stop responding to MEMOBUS/Modbus communications.
The drive must be configured with a slave address to enable the drive to communicate with the controller (master)
over MEMOBUS/Modbus communications. Set H5-01 to any value other than 0.
816
V/f CL-V/f OLV CLV AOLV
Selects the output signal level from the MFAO terminal FM.
V/f CL-V/f OLV CLV AOLV
Selects the signal level output from the MFAO terminal AM.
V/f CL-V/f OLV CLV AOLV
Sets the level at 10 V when U1-08 [Output Power] executes analog output.
V/f CL-V/f OLV CLV AOLV
Sets the communication slave address for drives.
