After the assembly, be sure to make inspections of lens operations.
Inspection items of lens operation
1. Inspection of GMR-encoder Operations
Activate the scanning drive of lens and check all the pulse numbers.
If GMR encoder is defective, the pulse number will be out of standard.
2. Inspection of Lens Driving Stop Accuracy
Check the overrun/underrun pulse number, compared with each lens drive amount, (i.e. deviation amount of
the stop position from the target position) upon lens driving.
3. Inspection of Lens Driving Time
Using an oscilloscope, check the each driving time (from starting to ending of servo-motor driving) upon lens
driving.
4. Inspection of Lens switches and Lens condition
Check ON/OFF operations of each switch, and the operating condition of focus encoder.
