PG/FG
The special PG pulse is derived from the negative-going
zero-crossing from the MOT3 output (pin 16). The external
PG signal (PG IN on pin 5) must sense a positive-going
voltage (
>
80 mV) within 1.5 to 7.5 commutation periods
before the negative-going zero-crossing in MOT3
(see Fig.8).
The voltage requirements of the PG IN input are such that
an inexpensive pick-up coil can be used as a sensor
(see Fig.9).
Example: If p = 6, then one revolution contains 6
×
6 = 36
commutations. The tolerance is 6 periods, that is 60
degrees (mechanically) or 6.67 ms at 1500 rpm.
If a PG sensor is not used, the PG IN input must be
grounded, this will result in a 50% duty factor FG signal.
