Setup and Operation
1.3.4.2
POWER MODULE OUTPUT VOLTAGE FEEDBACK
Up to 4 power module output voltage feedback signals are accommodated. These
signals may be useful for detection of position or speed (i.e., so called sensorless
operation). Alternatively, they may be used to correct for output voltage distortion which
occurs due to power device voltage drops and dead-time.
The signals are referred to as VPH_#1 - VPH_#4. VPH_#1 - VPH_#3 are assigned to
AN12-AN14, respectively. VPH_#4 is only brought to the analog prototyping header J6
and must be manually assigned if required.
1.3.4.3
DC BUS VOLTAGE AND RECTIFIED AC VOLTAGE FEEDBACK
The DC bus voltage and, for AC input power modules with PFC, the rectified AC
voltage is accommodated.
The DC bus voltage is assigned to AN11.
The rectified AC voltage, if used, is assigned to AN9.
1.3.5
Back EMF Crossing Detection
One method of operating a brushless DC motor without a position sensor has been
included in the design of certain power modules. This method relies on detecting when
the voltage of an inactive phase's output lead, due to it's back EMF, crosses the nomi-
nal center point of the DC bus. Comparators are included within the power module
which detect the crossover points.
Three such crossover signals are accommodated in the design. Two of these signals
can not be used at the same time as the Phase#4 firing signals (which are not required
by the power modules that provide the back EMF crossing signals).
If the user wishes to use the back EMF crossing signals then they must do the
following:
? Make sure LK4 and LK5 are in position 2-3.
? Make sure that no Hall commutation transducer is connected to J3. This is
because the three input capture channels are common.
