Potentiometer functionality based on open/closed loop driving strategy (continued)
If during the GUI configuration phase the "from RV1" control was unchecked, the value of
the duty cycle (or the value of the current reference) is not set by P1 but has a fixed value.
If during the GUI configuration phase the "from RV2 - RV3" control was unchecked, the
value of the rising delay coefficient and the value of the falling delay coefficient are not set by
P2 and P3 but have fixed values.
The maximum current allowed by the GUI has been set to 8 A (see
Stopping the motor (LED action)
Push the Start/Stop button to stop the motor. The LEDs toggle from green to red to indicate
an "idle" state.
Driving the BLAC motor
This section describes how to drive the brushless permanent magnet motor. You should first
check that the board has been set-up for BLAC driving (see
Specific sensor connections
In order to be driven correctly, the motor must have three position sensors, in this case three
hall sensors. For this demonstration we suggest using one Ametek BLDC blower motor
(voltage max 30 Vdc). Refer to the connections in
power board.
