ST92141 - 3-PHASE INDUCTION MOTOR CONTROLLER (IMC)

INDUCTION MOTOR CONTROLLER (Cont’d)

7.4.5.2 IMC Software Operating mode

In this operating mode, the Repetition register and

any Compare register can be independently up-

dated by software by setting the SDT bit in the

PCR2 register (this bit will be reset by hardware)

and the corresponding enable bit in the same reg-

ister.

No hardware loading is performed when an ADT

interrupt is generated.

Note: The Repetition Counter is decremented im-

mediately when the Repetition Counter is updated.

7.4.6 IMC Output selection

The IMC Output can be selected from the following

sources:

– OPR register (bit 5:0), by setting the ODS bit in

the OPR register.

– Dead Time Generator outputs, by setting the

ODCS bit in PCR0 register.

– PWM Counter outputs (h and l) are not comple-

mented when the ODCS bit is reset.

Figure 70 shows the IMC output selection.
