This parameter records the value of the "100% speed in rpm" parameter at the time the autotune was carried out.
"100% speed in rpm" determines the max speed at which the motor can be commanded to run. When the autotune is carried out, it
can only measure the motor characteristics up to this speed. Beyond this speed, the motor characteristics are filled in according to the
best possible estimate, but are not necessarily accurate.
If at a later date the "100% speed in rpm" parameter is increased, then that will allow the motor to run in the region where the motor
characteristics have been estimated, not measured. The further into this region the motor is allowed to run, the less accurate will be
the motor characteristics and hence the control.
The user is allowed to increase "100% speed in rpm" up to 2 times the value stored in “Max Spd when Autotuned”. Beyond this it is
considered that the resulting control inaccuracy may be unacceptable. In this case, an error will be generated. If the user wishes to
run the motor more than 2 times the value at which it was autotuned, then he must carry out a new autotune at the higher speed.
