Speed PI Autotune [371]
The function speed autotune will perform a torque step change, and mea-
sures the reaction on shaft speed.
It automatically sets the internal speed I time to its optimum value. The speed
PI autotune must be done during operation with the motor load connected and
the motor running. “Spd PI Auto” will be blinking in the display during the auto-
tune operation. When the test is successfully concluded, the display will show
“Spd PI OK!” for 3 s.
Communication information
Note
Run the autotune at speed lower than 80% of the nominal motor speed.
Otherwise autotune will fail.
Note
The setting will automatically return to Off when the autotuning is finished.
Note
This menu is only visible if VSD Mode = Speed or V/Hz.
For adjusting the P gain of the internal speed controller. The speed P gain
must be manually tuned for a faster reaction to load changes. The speed P
gain can be increased until there is audible noise from the motor and then
decreased until the noise disappears.
