Parameter Values/Description
An AMETEK 24 V BLDC blower is the default
motor included in the AK-ST7FMC Starter Kit.
This motor features 3 Hall sensors but is
controlled in Sensorless mode by default. It can
also be controlled in Sensor mode (see below).
The “Default Settings” button restores the best
performance settings for this motor.
Any other BLDC motor (including compressor)
with or without sensors can be controlled by the
AK-ST7FMC Starter Kit. Motors (including
compressors) wound to use sinewave mode (so
called PMAC motors) can also be controlled with
optimum results in trapezoidal mode. Note that
all basic and advanced parameters are by
default those chosen for the AMETEK motor. It is
unlikely that these settings will suit your motor.
The AK-ST7FMC Control Panel can help you
find these parameters.
The default sensorless control method is the
STMicroelectronics patented three-resistor
method.
Other standard sensorless methods can be
implemented by modifying the Motor Control
board hardware and by selecting the appropriate
BEMF sampling method. All sensorless methods
implemented in this Starter Kit use a six-step
signal driving topology.
MCRA register, bit SR at 0.
To run the motor in Sensor mode you need to
properly set jumpers W14, W15, W16. You need
to connect sensors and respect sensor wiring.
