Speed Feedback with Discrete PID and PWM

Hi, i've got a problem with the blocks PID and the PWM Generator (2-Level) commanding a Universal Bridge connected to a PMSM machine from the power system block (the machines works when not closed in feedback). I got my feedback loop with the speed error signal which is driving the PID block. When i feed the output of the PID to the PWM generator, it exits 3 identical pwm signals (i've tried feeding the pwm block with the output of a 3-phase sinuosoid generator block, and it creates 3 different pwm signals with, obviously, identical duty cycle, amplitude but different phase). I can't realize how i can manage to modulate the pwm with the output signal from the PID....suggestions??
