MOTOROLA
The even numbered fault pins work almost the same way except that the
PWMs will be enabled on the next PWM cycle after the software has
acknowledged the fault andthe fault signal is negated. This provides
ultimate protection, even for the condition where the FTACK bit may
have been accidentally cleared (for instance, runaway code). Another
application would be when the software has granted PWM enabling by
clearing the FTACK bit, but in the meantime wants the PWMs to remain
disabled until the fault input is negated. At that point, the PWMs will
come back on line automatically. An easy way to remember the
difference between the odd and even fault pins is to think that the even
pins provide even more protection.
Take It to the Limit
in Automatic
Mode
Automatic mode is a unique operating mode where the PWM outputs
can be turned back on automatically at the start of the next PWM cycle,
assuming that the offending fault has gone away. The primary
application for this mode of operation is cycle-by-cycle current limiting,
as illustrated in
Figure 7
. A resistor inserted in series with the motor
develops a voltage when current is flowing through the motor. This
voltage is compared to a threshold representing a safe upper current
limit, and the comparator output constitutes the fault input signal. The
dashed portion of the PWM waveform indicates the normal duty cycle
that would have occurred without current feedback. The solid line shows
early termination of the PWM signal's "on" time resulting from the current
threshold being reached. Cycle-by-cycle current limiting allows the
motor current to be regulated automatically by the protection hardware
of the 'MP16, thus freeing the software to focus on other control tasks.
