① The method of connection of the rated voltage power supply and measuring tools is the same as
"ADJUSTMENT OF MR DUTY".
② Make sure that the electric current and voltage of the rated voltage power supply are set to the set values
on the PC screen.
③ Turn the rated voltage power supply ON.
④ In the adjustment for Electrical Device of the AF-S 18-135 inspection program, after " Adjustment for
MR-duty (Adjustment 1 of 2)", it automatically goes to "Adjustment for Frequency and Control (Adj. 2 of
2)". The lens automatically starts the driving of scanning.
⑤ When the above Fig.1 is displayed, if the motor driving stops, select "Yes" to complete the adjustment.
In case the motor does not stop driving, select "No " to make adjustments again.
In case the motor does not stop driving even after the readjustments, adjust the MR duty again and repeat
"ADJUSTMENT FOR DRIVING FREQUENCY & MOTOR CONTROL".
If the adjustment is not successful in spite of the above, the SWM unit, fix-tube unit, or MR head unit
may be defective.
