Hello,
I meet a problem when i ran the lab2a, the details are as follows:
hardware: my own designed driver board with F28069m.
software: motorware1.13 & ccs5.5 & v6.2.3 compiler
error occurred when EST_State_RampUp, the motor could just speed up for 2 or 3 seconds, and it stop at the speed didn't reach the "right" value.
I had changed USER_R_OVER_L_EST_FREQ_Hz from 100Hz to 300Hz, but nothing changed.
the motor rated current is 20A, and if i Enlarge USER_MOTOR_RES_EST_CURRENT from 2A to 3A(4A), the motor will more unstable and noise.
is there any factors related with RampUp i could check up.
and i think this Process is running in open-loop control, whether the current and voltage feedback unrelated?
sorry for my poor English, offers my sincerest respect.
