The operation panel can access and configure any settings stored in the inverter memory, extra
hardware is not necessary to reconfigure your new unit to the same condition as your old drive.
However, changing 300 parameters with the panel is a time consuming process. To get around
this, a computer software program can be used to upload the settings.

See paragraph 3-10,

Accessing Frequency Control Settings.

However, a few parameter settings with the operation

panel are required to initialize the communication with the new inverter. Once all the parameter
settings are loaded for the new inverter, you must perform an Auto Tune procedure, of the new
inverter/motor combination.

See paragraph 3-11, Auto Tune of

Drive

. The following

instruction shows how to initialize the unit:

2-8A Initial Configuration of Mitsubishi Inverters

The Mitsubishi Inverters must be manually configured before they can communicate over the RS-
485 connection to the computer. This configuration is performed using the FRU-DU04 Control
Panel. The Control Panel is connected to the inverter using an 8- pin straight through RJ-45
cable, or by directly mounting the Control Panel on the inverter using the straight through RJ-45
plug included with each inverter. It can only be connected to a single inverter at a time.

There are four (4) parameters that must be manually configured before the computer will talk to
any respective inverter. Following the steps outlined below manually configure the four initial
parameters.

1. Enter the parameter setting mode. Press the

MODE

button until “Pr” appears in the

display.

2. Select the Parameter Number. Press the

SET

button to directly enter a parameter number

one digit at a time. The

and

DOWN

buttons will move the flashing digit up or

down. Press

SET

button again to move to the next digit.

3. After the Parameter number is et, press the

SET

button to display the selected Parameter

Value.

4. Use

the

and

DOWN

buttons to adjust the parameter value.

5. Save the new value. Press the

SET

button and hold it down for at least 1.5 seconds.

When the value has been saved, the Control Panel will beep and display will begin to
flash between parameter and the value.

6. Press

the

SET

button once to change the Parameter Number using the

and

DOWN

buttons, then continue at Step 3; or Press the

MODE

button 5 times and continue at Step

2 to directly enter a Parameter Number.

Figure 4 Key Operation (FRU-DU04) NOTE pg 47, Mitsubishi Inverter Manual.

NOTE:

To insure that the entered values take into EPROM memory of the inverter you must

hold the set button for approximately two seconds or until parameter number and set value
numbers flash back and forth.

1. Power up the inverter.
2. Connect the operation panel to the PU connector on the inverter by using a standard 10Base-

T networking cable (or the modular jack type relay connector that comes with the unit), the
panel LED display should come on upon the connection.

3. Change to parameter setting mode by using the MODE key.
4. Set parameter write disable selection (Pr.77) to

5. Set station number (Pr. 117) according to its driving axis

. (Pitch=0, Roll=1, Lift=2,

Counterweight=3)
