Thx Richard, now I understand.

Now, AN6 work corectly. The value of CCPR1L is 2 x adval. If I divide adval to 2 , exist a little diference betwen PWM1 and PWM2 on outputs (~ 0,8 units)

Code:
t2con=4
PR2 = 255
ccp1con=12

pause 200
'========================PROGRAM=============================
main:
adcin 6 , adval 
pause 10

CCPR1L = adval/2            ;set pwm
duty1 = adval

hpwm 2 , duty1, 2000 

high inh1
high inh2

goto main
end
