2-11 AUTO TUNE OF THE INVERTER CIRCUIT
FIGURE 3
After inverter has been replaced, initialized and settings checked, you must perform an “AUTO TUNE” of
that inverter. This is required so that the inverter memory knows the voltage values, motor current draw,
RPM of motor and knowledge of all associated wiring. This must be completed before you can use that
inverter drive in our regular program. Perform the test in the following sequence. It is imperative that there
are no persons near the motion platform for this test.
WARNING: During the following test it is possible that the motion platform could
move due to inadvertent actuation of the drive motor being tested. All personnel
must stay clear of all rotation planes associated with this unit. Injury or possible
death of person/s is very possible.
Perform the “AUTO TUNE” test as follows:
1. Ensure power is applied to the inverters
2. Ensure inverter is initialized and all parameters have been checked
3. Open the “Mitsubishi Frequency Control Interface” program
4. Click “OFF LINE” square, it will turn to say “ON LINE”
5. Click Block read and the window will state that all program parameters are OK or there is a problem.
Click “OK”
6. Click on top row “TEST SYSTEM” then select “AUTO RUN”.
7. Red “X” will show in a window stating for you to enter a change setting in parameter 96
a. Enter the number “1” to run auto run without turning the platform
b. Enter the number “101” to actually move the platform. Do not use this test unless
absolutely necessary. Always use step (a.) above. Read the above warning before
continuing.
8. When you entered the number “1” in parameter 96, click Block write then click “OK” for the rest.
9. The window now allows you to either initiate a forward or reverse auto run test.
10. The bottom of the window will show a step of green blocks, this shows you that the system is testing.
Select AUTO TUNE from
Test Running, top line
Parameter (96) must be changed
b
efore test can be initiated. See
step # 7 below for warning
These windows will show status
of test. All green means all is
