Potentiometer functionality based on open/closed loop driving strategy (continued)
If during the configuration using GUI , the "From RV1" control has been unchecked, the
value of duty cycle (or the value of current reference) is not set by P1, but has a fixed value.
If during the configuration using GUI, the "From RV2 - RV3" control has been unchecked,
the value of the rising delay coefficient and the value of the falling delay coefficient are not
set by P2 and P3, but have fixed values.
The maximum duty cycle allowed in voltage mode depends on the value of PWM frequency
and the value of PWM min off time set by the GUI.
The maximum current allowed has been set to 4.1A. (see

Stopping the motor (LED behavior)
Push the Start/Stop button to stop the motor. The LEDs toggle from green to red to indicate
"idle state"
It is possible to configure the system to drive the BLDC motor in current mode and or in
closed loop and restart the demonstration from

Driving the BLDC Motor (trapezoidal - sensored)
Before proceeding with the motor control demonstration, the power board STEVAL-
IHM011V1 must be set up to drive "3 Phase BLAC/DC (trapezoidal - sensored)" settings as
described in the power board user manual.
Let's start the demonstration driving the brushless permanent magnet motor in voltage
mode - open loop - sensor 60° . At this point please check that the control board has been
maximum current allowed.
