Sets the coefficient used to compute the delay when the BEMF is
rising.
MWGHT register.
Sets the coefficient used to compute the delay when the BEMF is
falling.
MWGHT register.
Closed Loop parameter. For beginning with a new motor, it is
recommended to start from 0. The higher the value, the shorter the
time necessary to cancel the static error, but a value too high will
render the system unstable.
Closed Loop parameter. The higher the value, the lower will be the
static error, but a value too high will render the system unstable.
The time interval between two PI control samplings. The lower the
sampling time the better will be the regulation bandwith. However, a
value too low will not increase the system dynamic response above a
certain point, and will consume microcontroller resources.
Rotor speed reading.
This value can be read in Hz or RPM (click the “Hz” or “RPM” button
next to the value to switch between units).
Available in Closed Loop only. Displays the duty cycle computed by
the PI control, which is directly applied on power switches (in Voltage
mode), or used to modulate the current reference (in Current mode).
