Refer to Figure 2-9 and note the generated output voltages of the amplifier relative to the
Hall sequences applied to HALL A, HALL B, and HALL C connections at connector
J6. For proper operation, the CEMF generated motor phase voltages should be aligned to
the amplifier’s output generated voltage with the given Hall effect sequence shown in.
If the sequence of Hall signals relative to the generated motor voltage (e.g. motor CEMF)
is adhered to as illustrated in Figure 2-9; a positive (+) voltage signal applied to pin 8
(+INPUT) of connector J6 relative to pin 21 (-INPUT) of J6 or pin 14 (signal common)
of J6 produces a CCW (e.g., a negative rotation) rotation of the motor shaft as viewed
from the front of the motor.
