9.

Set PC master software control mode and start motor (see

 

 

Application Control and PC Master Software (Remote)

 

 

Operating Mode)

 

10.

Set the speed to the middle of minimal and maximal speed

 

11.

Increase, step by step, the proportional gain

 

 

SPEED_PIREG_P_GAIN with PC master software, until speed

 

noise or oscillation appears, or up to 128

 

12.

If SPEED_PIREG_P_GAIN is set to 128, increase proportional

 

gains in SPEED_PIREG_P_GAINSCALELEFT further with PC

 

master software, steps 0, 1, 2 ... 8 otherwise leave

 

 

SPEED_PIREG_P_GAINSCALELEFT as 0

 

13.

Increase, step by step, the integral gain SPEED_PIREG_I_GAIN

 

with PC master software, up to current oscillation or noise, or up

 

to 128

 

14.

If SPEED_PIREG_I_GAIN is set to 128, do further integral gain

 

increases to SPEED_PIREG_I_GAINSCALELEFT with PC

 

 

master software, steps 6, 5, 4...0; otherwise, leave

 

 

SPEED_PIREG_I_GAINSCALELEFT as 7

 

15.

You can further evaluate the setting of the regulator parameters in

 

order to get a smoother current waveform until the regulation

 

 

seems to be performing well

 

16.

Open const_cust_x.h and modify the regulator parameters with

 

the final variable values evaluated with PC master software

 

17.

Start motor (see Application Control and PC Master Software

 

(Remote) Operating Mode)

 

18.

Set minimal desired speed

 

19.

If the displayed real speed is not able to go down to the desired

 

minimal speed, it is necessary to decrease minimal PWM duty

 

cycle DUTY_PWM_MIN in const_cust_x.h!

 

20.

Then, you can tune dynamic characteristics of speed regulators

 

(steps 22. to 29.) or finish tuning the regulators

 

21.
