OKK VP400 5 AXIS Z AXIS OFFSET ERROR WHEN MACHINE TURN A AND C AXIS

HELLO
TO ALL
I HAVE A PROBLEM IN THE MACHINING OF THE ROTARY AXLES OF AN OKK VP400 THE G54 IS ABOUT THE MASTER PART WITH THE A Y C AXES IN ZRN EXACTLY AT 0.026 THOUSANDS UP FROM THIS WHEN A MEASURE VERIFICATION IS CARRIED OUT IN THE FOUR FACES OF THE MASTER BLOCK MESURES AS FOLLOW :
SIDE 1 MEASURE 0.024 "
SIDE 2 MEASURE 0.030 "PLACED BELOW SIDE 1
SIDE 3 MEASURE 0.018 "
SIDE 4 MEASURE 0.033 "
THE MEASURES ARE ALWAYS PERFORMED WITH THE PART ORIENTED PLANE XY
I TRY TO MOVE THE PARAMETERS OF FANUC 19700,19701, 19702 AND NO CHANGES ARE ALREADY REMAINED. (THE PARAMETER CHANGES BUT THERE IS NO CHANGES PHYSICALLY)
THE GEOMETRY OF THE AXES A AND HAVE BEEN VERIFIED ITS PLANNING IS BELOW 0.010mm 0° AND 90°
I hope someone has information on how to enable the compensation of axes A and C OR WHY Z AXIS IS COMPENSATE IN THIS WAY I WILL APPRECIATE THE HELP
