Adjustment of Driving frequency and Motor control
● In case of replacing the main PCB, SWM unit and MR encoder unit, be sure to make adjustments.
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 Select "2. ADJUSTMENT FOR DRIVING FREQUENCY & MOTOR CONTROL" in the menu of the
AF-S DX18-55 inspection program. 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.
