the machine to be higher than expected, which in turn causes the estimated speed to be inaccurate.
The rotating autotune calculates the actual field current required to produce a 100 % field flux at ¼ rated speed with no load. This compensation
makes the estimated speed calculation more accurate. The rotating autotune sets this value in the range of 80 % to 100 %.
On motors with a high level of armature reactance the autotune level may need to be increased so the field is always fully fluxed.
