Servo System
3. When the speed control voltage is received by the servodriver, it rotates the
motor at a speed corresponding to the speed control voltage. The rotational
speed is in proportion to the speed control voltage.

Rotational speed +N (rpm)
4. The rotary encoder directly connected to the motor axis rotates in sync with
the motor and generates feedback pulses.
5. The feedback pulses are subtracted until the error counter goes to zero.
When the error counter goes to zero, the speed control voltage to the servo-
driver becomes zero and the motor stops rotating.
