Hook-up Procedure for Motors with Timing Diagrams

It is prudent that when first testing the motor a DC ammeter be placed in series with the DC source.
Zero to twenty amperes is fine (an analog movement is preferable).
Most manufacturers of BLDC motors send timing diagrams with their product. These diagrams show
the sequencing of the Hall sensor outputs as related to the three motor phases. See pages 9 & 10.
The Hall sensor sequencing is very useful, but since everyone has a slightly different way of notating
the same information, deciphering the motor phases is typically quite confusing. The recommended
procedure is to hook up the sensors according to their diagrams, then test for the proper motor phases.
The current limit circuitry will protect the control from miswired phases.
First, determine the spacing of the motor Hall sensors. They will either be 60 or 120 degrees. Usually
the motor manufacturer will supply the spacing. If they don't, compare the sensor diagram sent with
the motor with those at the end of this manual. Observe that 60 degree spacing will, at some position,
have all sensor lines at logic high. With 120 degree spacing, all three sensors are never at the same
logic level at the same time.
Once the spacing is determined, make sure the control is set correctly. Return to the correct wiring
diagram and connect the sensors to terminals S3, S2 and S1 of P1. Notice that for the 60 degree
spacing there is a specific sensor line that leads the sequence, followed by a line lagging by 60 degrees,
and a third line lagging the second by 60 degrees. It is important that the middle line in the train be
connected to terminal S2 of P1.
After the sensors are connected, attach the sensor power line to terminal 6.25V of P1. The sensor
common line is connected to terminal COM of P1. Now attach the three motor armature wires and
test for proper hook-up.
It is recommended arbitrarily attaching the phase lines to terminals P1, P2, and P3 of connector P1.
Choose a configuration, test it, and then keep track of the results on paper.
