Sets the duty cycle percentage from 0% to 100%.
Sets the current reference value from 0 A to the
maximum current allowed.
After power-on, the control board’s green LED should blink, signaling that the firmware has
started to run. After a while a green LED stays on indicating an "idle" state.
Setting the potentiometers
Before running the motor, the three potentiometers P1, P2, P3 must be set
the correct configuration).
Running the motor (LED action)
Push the Start/Stop button. After pushing the button the LEDs toggle from green to red to
indicate a "run" state. The motor starts running.
During any state: idle, start, run or brake, a still red LED together with the brake of the motor
indicates a fault condition. A fault condition is due to one of the following:
●
●
●
●
●
Blinking of the red LED during the running of the motor indicates that a software current
limitation is in action.
Changing the real-time parameters
The real-time parameters can be changed using the control board’s potentiometers.
Table 19
Potentiometer functionality based on open/closed loop driving strategy
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: the start-up phase ends without getting a sufficient number of valid zero
crossing events.
Motor stalled: during the running of the motor no zero crossing events have been
observed.
explains the potentiometer functionality based on the driving strategy.
