RX220 YROTATE-IT-RX220 Motor Control Kit
In our case, at 350 it started to be very unstable, but the motor is still running. Set the speed to "0".
Then use half of the found value: 175 in our case, click on "write" and set the speed to 2000 RPM.
Do the same for the parameter n°14 which is the speed loop Ki parameter. Increase it until it becomes unstable.
In our case the critical value is reached at 2800 for Ki, so the value to be used is: 1400.
n) Test now all the speed ranges and different rotation.
o) Finally the parameters list can be saved in a file in .CSV format for further used and can also be uploaded later on:
