i have DELTA 28SV PLC AND I USING SPD X1 K1000 D100 COMMAND FOR SPEED DETECTING(X1 ENCODER A PHASE) THEN SAME D100 USED FOR SERVO CONTROLS LIKE THIS DPLSR D100 K500 K100 YO. WHEN I CHANGE THE ENCODER SPEED IT WILL EFFECT ON NEXT SECOND OR NEXT COMMAND EXECUTION. SO I NEED INSTANT SPEED VALUE OF ENCODER FOR SERVO CONTROL.
