INSTALLATION AND WIRING
Terminal name Description
For the power supply (5 V) for the encoder
For the incremental sine signal output from the sinusoidal encoder
For the incremental cosine signal output from the sinusoidal encoder.
The cosine signal has a phase difference of 90 degrees with respect to
the sine signal (phase A).
For the home position signal output from the sinusoidal encoder
For the sine signal taken from the Z1 track of the sinusoidal encoder
(one period per revolution)
For the cosine signal taken from the Z1 track of the sinusoidal encoder
(one period per revolution)
