Lab Experiment for AC Position Control System

EXPERIMENTS

 

EXPERIMENT 1:

 

AIM:

To study the Operation of AC servomotor position control with PI controller using PS-CS-APCS.

APPARATUS REQUIRED:

  • PS-CS-APCS
  • Motor Set up
  • Patch Chords.
 

 

PRECAUTIONS:

  • Check whether power ON/OFF switch is in OFF condition.
  • Check whether 230V AC ON/OFF switch is OFF condition.
  • Check whether main winding voltage 230V AC is in OFF condition.

 

CONNECTION PROCEDURE:

  • Connect set position (SP) to error detector (SP) input.
  • Connect position feedback (PV) to error detector (PV) input.
  • Connect 12-0-12V output of centre table transformer to input 12 - 0 -12V of power circuit.
  • Connect output of power circuit to motor control winding CV output to motor input.

 

EXPERIMENTAL PROCEDURE:

  • Switch ON the trainer power ON/OFF.
  • Switch ON the constant 230V AC main winding voltage.
  • Switch ON the transformer primary 230V AC ON/OFF switch.
  • Set the motor position using set position knob and take the reading for set position and output position and tabulate it in table 1.
  • Repeat the same procedure step by step up to 340°.
  • For each step note down set position and output position and tabulate it in table 1.
