Checking and setting the encoder for a TOE turret |
If you have to change the turret encoder, it is very important to set the position of the encoder. Make sure that the turret is locked in any position. Rotate the new encoder until the turret disk position and the encoder position bits are matched (you can check this on the diagnostic screen of the control, or measure the position bit signals at the wire terminal).
At that point, rotate the encoder slowly in one direction, until the strobe signal will be low and make a mark on the encoder bracket. Rotate the encoder in the opposite direction until the strobe signal will be low again and make the 2nd mark. Rotate the encoder back between the two marks, and secure the screws. The strobe signal needs to be on in order to energize the solenoid of the pre-indexing pin. |
