How to adjust
① Make sure that the electric current and voltage of the connected rated voltage power supply are set to the set
values. Then, turn the rated voltage power supply ON for the contacts A and F.
② Select "MR DUTY ADJUSTMENT" in the menu of the AF-S DX-zoom 17-55 inspection program.
③ The display for checking whether the fixed values are written in EEPROM appears. Select a proper item.
④ According to the instructions on the screen, rotate the MF ring from the near distance to the infinity to the near
distance direction slowly by hand. Make sure that the waveform on the oscilloscope has duty 50% and then stop
the MF ring at the near distance end.
⑤ According to the instructions on the screen, rotate the MF ring from the near distance to the infinity direction
slowly by hand. Make sure that the waveform on the oscilloscope has duty 50% and then stop the MF ring at the
infinity end.
Note:In case the waveform from infinity to close distance position or vice versa does not have duty 50%, repeat
"INSPECTION AND ADJUSTMENT OF THE MR ENCODER OUTPUT WAVEFORM" on Page L20.
●In case of replacing the main PCB, SWM unit or MR encoder unit, be sure to make adjustments.
① The connetion of the rated voltage power supply and measuring tools is the same as "ADJUSTMENT OF MR
DUTY". Turn on the rated voltage power supply.
② Make sure that the current and voltage of the rated voltage power supply are the set values.
③ Turn on the rated voltage power supply.
④ Select "ADJUSTMENT FOR DRIVING FREQUENCY & MOTOR CONTROL" in the menu items of the AF-S
DX-zoom 17-55/2.8G inspection program. The lens starts scanning automatically.
⑤ When the abobe display apears and the motor stops driving, select Yes (Y) to end the djustment.
If the motor does not stop driving, select No (N) to make the adjustments again.
If the afjustment is done again but the motor does not stop driving, adjust the MR duty again and then perform
"ADJUSTMENT FOR DRIVING FREQUENCY & MOTOR CONTROL" again.
If the adjustment is not successful yet. the SWM unit or cam ring unit may be defective.
・Menu items
The items 1 and 2 are used for adjustments.
The item 3 is used for reading and writing EEPROM DATA.
The items 4~7 are used for inspections.
・Selection items
After selecting any item, one of the lens selection display, the focal length selection display, the voltage setting,
display, the inspection start display, etc. appears. The displays are differrent depending on the items. Follow the
instructions of a personal computer.
・Operating voltage
・Initial driving
When "WAIT FOR SOME SECONDS" appears, perform the initial driving (drive scanning five times and stop at
infinity-end).
Caution:If the MF ring is rotated during lens scanning, error value is shown the pulses.
Do NOT touch the MF ring during operations.
Execute inspection for the 5 positions as below.
When the inspection is ended, the inspection result appears in the next page.
The total number of pulses when inspecting must be within the standard.
Standard of the total pulses : 4044 ± 125 PLUSE(S)
OK
CANCEL
Caution:If the MF ring is rotated while the lens scanning is driven, the pulse shows an abnormal value. Do NOT
touch the MF ring during operations.
During the lens driving, the above screen is displayed. Make inspections at the 5 positions as below.
The number of overrun/underrun pulses must be within the standards after the 5 lens back-and forth driving motions
("5/5TIME (S)." in [1] of the display).
If the lens stops while inspecting the lens-servo stop accuracy, select "3.SET DELAY-TIME" and input a
figure from 0 to 1000 for the delay time (msec: millisecond) to prevent stopping the lens into the entry field
of "DELAY-TIME" of the below.
Note:
The value of "ADUST DELAY-TIME" is set by the adjustment software. So, if the lens does not
stop during the inspection of "LENS DRIVING STOP ACCURACY", any value can be input without
problem.
However, the larger the value of "ADJUST DELAY-TIME" gets, the longer the inspection time becomes.
