versions   
Note: please check the driver firmware version through U2-07. 
 
6.4.4 Internal instruction auto-tuning steps 
Driver panel auto-tuning steps 
1.  The inertia identification is carried out, and the inertia estimation steps please refer to chapter 
6.2.4 operation steps. 
2.  Enter F0-09, panel display is iat-; 
 
3. Press ENTER, panel display is iat--, servo is in enabled status right now; 
 
4. Press INC or DEC, panel display is tune and flashing, enter auto-tuning status;   
 
5.  Driver will  automatically send  pulse instructions, if  the auto-tuning is  successful, the  panel 
shows done and flashing.   
                                               
6. Press STA/ESC to exit internal instruction auto-tuning.   
Note: In the process of auto-tuning, press STA/ESC will exit the auto-tuning operation and use the 
gain parameters at the exit time. If auto-tuning fails, it is necessary to initialize the driver before 
auto-tuning again. 
 
  Panel alarm in auto-tuning process   
Failure to search for optimal gain 
Too large inertia ratio; too weak rigidity of 
mechanism 
Overtrip alarm in auto-tuning process   
Please make  sure  that there  is no overrun 
and alarm before auto-tuning. 
Driver is not in "bb" state at the time of
