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 2.
5. Set station number (Pr. 117) according to its driving axis. (Pitch=0, Roll=1, Lift=2,
Counterweight=3)
6. Set number of communication retries (Pr. 121) to 9999.
7. Set communication check time interval (Pr. 122) to 9999.
Important: The inverters must be reset (powered off then back on) in order for changes to
Parameter 117 (Station Number) to take effect.
8. Disconnect the operation panel, reconnect the RS-485 communication cable between the RS-
485 terminal outlet and the PU connector.
9. Make sure there is a connection between the RS-485 communication port and the computer
running the inverter setup program

2-9 Checking the Operation Panel Display at Alarm Stop
The alarm code is displayed on the operation panel to indicate the cause of a faulty operation.
Clear up the cause and take proper action. See Mitsubishi Inverter Manual attachment for error
code table.
For a history log of recent alarm stops, access the HELP MODE menu with the operation panel
FR-DU04. (See attachment I, “5) Help mode” for instruction).
After you have replaced and initialized the new inverter (paragraph 3-9), you must verify that the
rest of the settings for that inverter are correct. Since there are over 300 possible settings, you can
use the control console computer to access the inverter and its settings, and make changes as
needed for proper operation of inverter and the system. The following information is critical, you
must address the correct inverter to
check or make changes. This is done by knowing the inverters
address, where it is located and how the computer finds each separate inverter. Since there are four
frequency drive inverters you must follow these addresses and have the correct part number listed
for each axes. They are as follows:
1. Node 00 --- is for the Pitch Inverter, Inverter part number ( Standard) FR-A520,
size 3.7/ (Foreign) FR-A540,size 3.7
2. Node 01 – is for the Roll Inverter, Inverter part number (Standard) FR-A520,
size 3.7 (Foreign) FR-A540, size 3.7
3. Node 02 – is for the Lift Inverter, Inverter part number (Standard) FR-A520,
size 3.7 (Foreign) FR-A540, size 3.7
4. Node 03 – is for the C/W, Inverter part number FR-E520, size 0.1 (All)
NOTE! The inverter part numbers may vary if you are using this unit on foreign power ie: 220,
380, 440 or 477 VAC. Check install order for verification.
