STR91xFAxxx

Three-phase induction motor controller (IMC)
The STR91xFA provides an integrated controller for variable speed motor control
applications.
Six PWM outputs are generated on high current drive pins P6.0 to P6.5 for controlling a
three-phase AC induction motor drive circuit assembly. Rotor speed feedback is provided by
capturing a tachometer input signal on pin P6.6, and an asynchronous hardware emergency
stop input is available on pin P6.7 to stop the motor immediately if needed, independently of
firmware.
The IMC unit has the following features:
●
Three PWM outputs generated using a 10 or 16-bit PWM counter, one for each phase
U, V, W. Complimentary PWM outputs are also generated for each phase.
●
Choice of classic or zero-centered PWM generation modes
●
10 or 16-bit PWM counter clock is supplied through a programmable 8-bit prescaler of
the APB clock.
●
Programmable 6 or 10-bit dead-time generator to add delay to each of the three
complimentary PWM outputs
●
8-bit repetition counter
●
Automatic rotor speed measurement with 16-bit resolution. Schmitt trigger tachometer
input with programmable edge detection
●
Hardware asynchronous emergency stop input
●
A dedicated interrupt to CPU with eight flags
●
Enhanced Motor stop output polarity configuration
●
Double update option when PWM counter reaches the max and min values in Zero-
centered mode
●
Locking feature to prevent some control register bits from being advertently modified
●
Trigger output to start an ADC conversion
