The only difference between the PMSM and ACIM motor identification process in this state is that for ACIM motors a typical frequency of 5 Hz is used, as opposed to a typical of 20 Hz used for PMSM motors.
// During Motor ID, maximum commanded speed in Hz
#define USER_MOTOR_FLUX_EST_FREQ_Hz (5.0)
The following oscilloscope plot shows a zoomed in plot of a phase current, where the frequency is ramped up to 5 Hz. Note that the default ramp-up acceleration of 2.0 Hz/s, shown previously for PMSM in Section 7.6.5, is used for the ACIM example shown in Figure 7-7.
