Reference terminal
Frequency-division circuit in the servodrive processes encoder input signal by the mode of frequency-division,
which is output by differential bus mode. Interface circuit includes high-speed photocoupler interface and
differential chip interface. Take the example of encoder A phase pulse frequency-division output.
