The frequency of the current injection used to calculate RoverL is set by the following parameter in user.h, specifying the frequency in Hz.
//! \brief Defines the R/L estimation frequency, Hz
//!
#define USER_R_OVER_L_EST_FREQ_Hz (100)
For high speed motors, the default value of 100 Hz might cause the motor to spin or move back and forth. If that is the case for the motor under test, increase this frequency to a higher value using 50 Hz increments until the motor does not move at all during the R over L state.
