MR encoder output-waveform inspection

● When the GMR unit is disassembled and replaced, be sure to make an adjustment.

1. Device:

　　・

Single-output rated voltage power-supply

1 unit: 5V 100mA

　　・

Oscilloscope

1 unit

　　・

Self-made tool

1 unit

Caution:

If there is a problem with continuity between the contacts of the self-made tool and the relay FPC,

the contacting surface of the relay FPC may be dirty, eroded, or oxidized. So polish the contacts and

connect them.

2. Preparation of the lens for measurement

　　・

Assemble the MR-head-attached zoom index ring unit, the SWM, and the MF ring into the lens body.

Then connect the assembled lens to each measuring machines as follows:

Self-made tool that is created by using
the main PCB of AF-S VR 18-200

GMR tape unit

Self-made tool

Rated voltage power-supply

(GND)

Set value
5.0 V
100 mA

Oscilloscope
(2ch type)

・

How to inspect and adjust:

①

Confirm that the electric current and voltage of the connected rated voltage power-supply are set values, then

turn it ON.

②

Set the oscilloscope, and turn the GMR tape unit by holding the focus coupling key.

Note

The waveform varies according to the rotational speed of the focus ring. So change “Time/Div” setting

accordingly.

Connect to the front-side connector of the

self-made tool PCB.
