H4-07
(0423)
Terminal AM Signal Level
Select
Sets the MFAO terminal AM output signal level.

(0, 2)
Note:
Set jumper S5 on the control circuit terminal block accordingly when changing these parameters.
0 : 0-10V

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 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 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:
• Re-energize the drive or set H5-10 = 1 [Modbus Register 0025H Unit Sel= 1 V units] 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.
