 - Sinusoidal (SIN_CTRL)
 - Field Oriented Control (FOC_CTRL) with the following 3 control modes that can be set in config.h file with parameter CTRL_MOD_REQ:
   - **VOLTAGE MODE(VLT_MODE)**: in this mode the controller applies a constant Voltage to the motors. Recommended for robotics applications or applications where a fast motor response is required.
-  - **SPEED MODE(SPD_MODE)**: in this mode a closed-loop controller realizes the input speed target by rejecting any of the disturbance (resistive load) applied to the motor. Recommended for robotics applications or constant speed applications.
+  - **SPEED MODE(SPD_MODE)**: in this mode a closed-loop controller realizes the input speed RPM target by rejecting any of the disturbance (resistive load) applied to the motor. Recommended for robotics applications or constant speed applications.
   - **TORQUE MODE(TRQ_MODE)**: in this mode the input torque target is realized. This mode enables motor "freewheeling" when the torque target is `0`. Recommended for most applications with a sitting human driver.
