use of quadrature encoder feed back connecting to micro controller are plc

[raman00084]

i am having a panasonic servo drive and motor that accepts step and direction signals. The encoder from the motor is connected to the servo drive and there is an option to take encoder feedback and connect to plc are micro controller. my doubt is that if i give 2000 pulses from a micro controller like pic it makes one complete rotation what is the use of encoder feedback connecting to pic micro controller, it is already connected to the servo drive that adjusts automatically according to pulse. will there be any use of connect the encoder feedback to pic micro controller?

you could use the encoder feedback to check the motor speed and direction and display it?
