Connection and first execution of the electronic speed controller (ESC) program
7.
Generate on J3 connector a PWM signal at 490 Hz and duty cycle value between
1060 µs and 1860 µs, the motor starts to rotate respectively from the minimum to the
maximum speed. The ESC is not armed (no driving signals generated) if the duty cycle
is lower than 1060 µs.
Note:
In case the motor is already started, a blank time of 1500 ms on the PWM signal determines
the switch off of the system (ESC turned OFF).

Second case: daughterboard removed

Set the SWD interface inside the IDE tool, for instance, a picture of IAR Workbench is
shown in
If the daughterboard is removed the following pad connections are available on it:
•
On the top side -> SWDIO, SWCLK
•
On the bottom side -> NRST, +10V,+5V, 5V_ESC, GND
