2.

 

Insure that the turntable is positioned to allow more than a full 
revolution of travel in the clockwise direction and use the 

STEP

 keys to run the turntable clockwise a few degrees to 

remove any play in the table. 

3.

 

Mark the current location of the turntable against the ground 
ring (masking tape works well), and set the current position 
reading to 000.0. 

4.

 

Using the 

STEP

 keys, rotate the turntable clockwise until it is 

again aligned with the mark on the ground ring. For best 
results, the last motion should always be in the clockwise 
direction to insure that any play in the gearing between the 
motor and encoder is accounted for. 

5.

 

Record the reading of the display, ignoring the decimal point 
(i.e. 360.0 would be 3600). This is the encoder calibration 
value.  

NOTE:  If the value is below 3600, the resolution of the 

encoder is low and thus the 2090 will not provide 0.1 degree 
resolution, even though the display shows that digit.  If the 
value has gone past 9999, the encoder has too many counts per 
meter and the 2090 can not correct for it.  In this case, contact 
ETS-Lindgren for assistance.

 

6.

 

Enter this value for the encoder calibration value and reset the 
limits and position information. 

7.

 

Test the turntable by moving it a complete revolution and 
comparing the alignment marks.  It may be necessary to adjust 
the encoder calibration value up or down slightly depending on 
the result.  

NOTE:  When scanning between limits, it is not 

uncommon to have a small discrepancy between the absolute 
position of the table and the display on the 2090.  This is 
because reversing the direction of rotation reverses any gear 
play between the encoder and the table top, allowing that play 
to be visible in the positioning accuracy. 

 

TT CALIBRATION EXAMPLE  

 
The table is set at the 0 degree position. A piece of tape is placed 
on the edge of the TT to line up with the edge of the gearbox 
cover. The table is stopped when the tape travels exactly 360
