Sensor-less Motor Start-up Parameter
The parameters for sensor-less motor start-up are shown as below. When the sensor-less motor do not start well, the
parameter can be modified to improve the start-up performance.
Motor Protection Parameter
The speed range and the phase current of the motor and other protection parameter for the motor control can be modified
at this part.
A . 1 . 1 H a r d w a r e S e t t i n g
The Hardware settings for the HW can be set in the H file ‘H05_user/ HardwareConfig.h’
Clock and ADC Set
The MCU clock and the ADC port and relevant coefficient are set at this part.
