Development Tool Compatibility
When using the development equipment with some motor control
micros, extreme care must be taken or damage may result to the motor
and the drive under development. For example, when a break point is
encountered in the code stream, some micros just leave the PWMs on
with their present pulse width, or worse, freeze the PWMs in their
present states. For many motor types (including AC induction motors),
either of these conditions causes the motor to stop abruptly, resulting in
potential damage to the motor drive.
The 'MP16 was designed to take emulation tool support into
consideration by negating all of the PWMs (driving them hard off) under
break conditions. This disables the power stage, resulting in the motor
coasting safely to a stop.
Whose Fault is It
Most motor drives on the market today have earned a reputation for
being robust and "bulletproof" thanks in large part to their fault tolerance.
Sensing of such parameters as bus voltage, heat sink temperature, and
over-current conditions as means of protection are becoming more and
more commonplace. Signals representing these parameters are often
supplied to an analog-to-digital (A/D) converter and then regulated by
software. However, if corrective action is required immediately, software
alone is often inadequate to provide the necessary protection. For this
reason, such system parameter signals are often compared in hardware
against a threshold that represents an unacceptable level, and fault
signals are created to disable the drive immediately. Therefore, the
drive's microcontroller should have the capability to process these
signals, and immediately disable the PWM outputs when a fault
condition is present.
However, most microcontrollers on the market today can accommodate
only one fault signal, requiring the hardware designer to include extra
circuitry just to gate all the fault signals together. It is left up to the
software engineer to figure out which signal is responsible for the fault.
