4.2 Practical example of Hall, Motor and MiniAx phasing.
Read the Initial Start Up note carefully. Especially if:
A) The Brushless motor wasn't purchased through and paired with the MiniAx by CONTROL TECHNIQUES.
B) the Brushless motor doesn't appear in the indicated identification table.
If this is the case, follow the following notes carefully:
1) A DC power supply from an insulated transformer (output must be between 24 - 80VDC).
2) A speed reference (A potentiometer "see figure previous connections) or a 1.5 - 3V battery.
3) Brushless motor with (60° Hall Cells or 160° Hall Cells powered with +5v).
4) A MiniAx.
5) An Enable switch (can be substituted by a wire bridge).
PROCEDURE:
--If present, Encoder channels were not mentioned to facilitate proper phasing research. They will be
connected to the drive at the end of the following procedure.
--Verify the necessary power supply values for Hall effect Sensors. the drives are preset at the factory t
supply +5V on the +V terminal.
--Connect DC Power Supply between +AT and AT. (Be sure that they are sectioned and properly protected.)
--Connect potentiometer as on page 33, or the battery between +ref and -ref.
--Preset the switch between +10V and enable or a wire bridge. the Enabling happens by putting positive
voltage on the enable pin.
--Connect the Hall Signals between the motor and drive.
GND , +V ,Hall A , Hall B , Hall C.
--Enable MINIAX and turn motor shaft. If the OK LED remains on and the AH LED is off, the motor has Hall
Effect Sensors 120° and all 3 signals are present.
If turning the motor shaft the AH LED comes on, the causes may be the following:
1)the motor has Hall Effect Sensor of 60°. In this case, close solder bridge S10 and try again. All of this
must be done with the power supply off.
2) Hall Effect Sensor's are not powered.
3) Hall Effect Signal is missing. check with multimeter.
--Insert the 3 unknown motor phases in U V W which we will call A B C. There are 6 possible combinations
to find the correct phasing. They are:
UVW
1) A B C
2) A C B
3) B A C
4) B C A
5) C A B
6) C B A
Only one of these combinations is correct.
--Power MiniAx and enable it.
If the motor turns (even at low speeds and delivering torque) in both directions CW and CCW the U V W
connections are correct.
The other 5 combinations (wrong) could cause the following:
-- the motor turns at max. speed without the possibility to control it by reference signal.
--vibration when motor is still in torque without the possibility to control it by reference signal.
-- Intermittent motor movement felt when touching the motor shaft.
Upon finding the correct U V W combination use it to connect the motor and drive.
