Optical Encoder

The above time/temp test should have already

 

 

been performed. Remove dust cover from the

 

 

gearmotor and inspect the coupling and encoder

 

 

disc. The coupling set screws should be tight and

 

 

not slipping on the motor shaft or the tach.

 

 

generator shaft. The encoder disc should be firmly

 

 

attached to the coupling and not warped. Check the

 

 

positioning of the optical encoder disc. The disc

 

 

should not be touching the optical encoder

 

 

assembly and the encoder assembly should be

 

 

mounted so it is squarely facing the coupling shaft.

 

 

This is to allow the infrared beams to be broken by

 

 

the encoder disc. If all this is okay, then replace the

 

 

optical encoder assembly.
