ST92141 - 3-PHASE INDUCTION MOTOR CONTROLLER (IMC)

INDUCTION MOTOR CONTROLLER (Cont’d)

If the 11-bit Compare register value is greater than

the extended Compare 0 Register (the 11th bit is

set to ‘0’), the corresponding PWM output signal is

held at ‘1’.

If the 11-bit Compare register value is 0, the corre-

sponding PWM output signal is held at ‘0’.

Figure 65 shows some Zerocentered PWM wave-

forms in an example where the Compare 0 register

value = 8.
