Parameter name
"3-phase BLAC/DC (trapezoidal)" basic parameters
Number of pole (north/south) pairs in the motor.
Manner in which to run the motor, either open loop (without speed regulation) or closed
loop (with speed regulation).
Software current limitation value (only in voltage mode): if the current flowing inside one of
the three phases of the motor reaches this value, overcurrent is not generated but the
pwm is managed to limit the current at this level.
Back EMF (BEMF) detection mode (rotor position), either sensorless, hall (effect) sensor
60°, or hall (effect) sensor 120°.
Percentage of final duty cycle applied at the end of the alignment phase (only in voltage
mode).
Value of current flowing inside the motor at the end of the alignment phase (only in current
mode).
Duration of the alignment phase in milliseconds (ms).
Mechanical acceleration rate of the rotor during the ramp UP in RPMs (or Hz) per second
(alternate between RPM and Hz settings by clicking on the RPM button).
Duty cycle percentage during the ramp UP (only in voltage mode).
Value of current flowing inside one of three phases of the motor at the end of the
acceleration phase (only in current mode).
Number of consecutive Z events that occur before the microcontroller runs the motor in
auto-switched mode.
Maximum target rotor frequency in closed loop, expressed in Hz.
When the "From RV1" checkbox is selected:
– duty cycle value is defined by the RV1 potentiometer (only for voltage mode), or
– current reference is defined by the RV1 potentiometer (only for current mode), or
– target speed is defined by the RV1 potentiometer (only for closed loop).
If this box is unchecked, the above parameters are set by the user.
Duty cycle percentage when the motor is run in "open loop voltage mode".
Value of current flowing inside one of three phases of the motor at run time in "open loop
current mode".
Target mechanical (rotor) speed in RPMs (or Hz) if speed regulation is set to "closed loop"
(alternate between RPM and Hz settings by clicking on the RPM button).
When the "From RV2 - RV3" checkbox is selected, the value of the rising delay is defined
by the RV2 potentiometer and the value of the falling delay is defined by the RV3
potentiometer. If this box is unchecked, the above parameters are set by the user.
Motor driving mode, current mode or voltage mode.
Minimum target rotor frequency in closed loop, expressed in Hz.
