Quick Start
The following steps show the operation to spin a motor.
step 1. Connect motor phases and Hall sensor bias, ground and signal outputs.
The rotational direction determination is shown in Table 2. Terminals
are provided with:
•
For motor phases
o
Through halls UO, VO and WO inside the circle,
o
Pins UO, WO and VO, or
o
Pin header CON1 pin 1, 2 and 3 for U, V and W individually
(Hirose DF1-8)
•
Hall sensor bias
o
Pin HB and Pin GND
o
Pin header CON1 pin 4 and 5 for HB and GND individually
•
Hall sensor signal
o
Pins IN1 and IN2
o
Pin header CON1 pin 6 and 7 for IN1 and IN2 individually
step 2. Connect PWM signal to PWM pin of the board.
The connection points, described in step 1 and 2, are shown in figure 2
and 3.
step 3. Set appropriate duty cycle of PWM.
step 4. Connect power supply, and turn it on.
That’s all.
