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.
