Changing the maximum allowed bus voltage level
The board includes an over-voltage protection mechanism that protects the system,
preventing the motor from starting if the bus voltage is greater than a given voltage. If this
occurs, the red LED starts blinking.
This threshold value is coded inside the firmware and its default value is set to 29 V. To
change it, one parameter inside the source code must be modified and the executable must
be rebuilt. To do this, find the following definition inside the adc.c source file.
#define HVBUS_THRESHOLD
Refer to
replace the number 539 in the statement above with this value.
