VIONiC encoder system quick-start guide

This section is a quick-start guide to installing a VIONiC encoder system.

More detailed information on installing the system is contained on 

page 12

 and 

page 13

 of this installation guide. 

The optional Advanced Diagnostic Tool ADTi-100* (A-6165-0100) and ADT View software 

†

 can be used to aid installation and calibration. 

INSTALLATION

Ensure scale, readhead optical window and mounting faces are clean and free from obstructions.

If required, ensure reference mark selector magnet is correctly positioned 

(‘VIONiC readhead installation drawing’, page 4)

.

Connect the readhead to receiving electronics and power‑up. The set‑up LED on the readhead will flash.

Install and align the readhead to maximise signal strength over the full axis of travel as indicated by a Green flashing LED.

CALIBRATION

Cycle the power to the readhead to initiate the calibration routine. The LED will single flash Blue.

Move the readhead along the scale at slow speed (< 100 mm/s), without passing a reference mark, until the LED starts double flashing Blue.

The system is now calibrated and ready for use. Calibration values, Automatic Gain Control (AGC) and Automatic Offset Control (AOC) status are stored in readhead non-volatile memory at power down.

 

NOTE: 

If calibration fails, restore factory defaults by obscuring the readhead optical window on power-up 

(page 14)

. Repeat the installation and calibration routine.

Reference mark

Move the readhead back and forth over the selected reference 

mark until the LED stops flashing.

No reference mark

If a reference mark is not being used, the calibration routine should now be 

exited by cycling the power. The LED will stop flashing.
