Turning the P3 potentiometer modifies the "phase shift" parameter. To optimize driving, the
correct value of this parameter must be set. Finding the optimum value of the "phase shift"
can be useful to monitor the DC current provided by the power supply. You should try to
fine-tune the P3 potentiometer to minimize current absorption. When this parameter has
been found, the potentiometer P3 can be left at this value for all future tests.
During any state: idle, start, run or brake, a blinking red LED indicates a fault condition. A
fault condition is due to one of the following:

Changing the real-time parameters
The real-time parameters can be changed using the control board’s potentiometers.

Potentiometer functionality based on an open-/closed-loop driving strategy
If during the GUI configuration phase the "set phase shift according to Pf/F curve" control
was checked, the value of the "phase shift" is not set by P3 but is calculated at run-time
based on the Pf/F curve (see
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.
hardware overcurrent: current flowing inside the motor reaches a value greater than the
maximum allowed current of 7.65 A (see
Over-voltage: the bus voltage reaches a value greater than 29 Vac.
Over-temperature: the on-board temperature sensor measures a temperature greater
than 110° C.
Start-up failed: no signal is received from the sensors at the end of the start-up
sequence.
Motor stalled: during the running of the motor no sensor signal has been observed.
