Turn on the power supply. For this demonstration the power supply output voltage should be
set to 30 Vdc and current limitation of the power supply should be set to 4 amp. After power
on the control board LED behavior should be the following:
●
●
Setting of potentiometer
●
●
●
Running the motor (LED behavior)
Push the start/stop button. After pushing the button the LEDs toggle from green to red to
indicate "RUN state". The motor starts to run.
During any state: idle, start, run or brake, blinking of the red LED along with the brake of the
motor indicates a fault condition.
A fault condition is due to one of the following conditions:
●
●
●
●
●
Blinking of the red LED during the running of the motor indicates that software current
limitation is in action.
Changing real-time parameters
The real-time parameters can be changed using the potentiometers of the control board.

Red LEDs blink signaling that the firmware has started to run.
After a while a green LED stays on to indicate "idle state"
Set P1 potentiometer in middle position from full counter clockwise to full clockwise.
Set P2 potentiometer in middle position from full counter clockwise to full clock wise.
Set P3 potentiometer in middle position from full counter clockwise to full clockwise.
Hardware overcurrent: current flowing inside motor reaches a value greater than max
current allowed 4.1 amp
GUI)
Over voltage: bus voltage reaches a value greater than 280 Vac.
Over temperature: onboard temperature sensor measures a temperature greater than
60°.
Startup failed: startup phase ends without getting a sufficient number of valid zero
crossing events.
Motor stalled: during the run of the motor no other zero crossing events have been
observed.
