▲
Run the drive as a speed regulator long enough to stabilize the mechanical
characteristics of the load (bearings, couplings, etc.).
▲
Set the speed reference to 10% of TOP LINE SPEED (P.020).
▲
Run the drive and adjust FRICTION LOSS (P.123) until the speed loop PI output
SPD LOOP OUTPUT (P.299) is zero.
▲
Set the speed reference to 100% of TOP LINE SPEED (P.020).
▲
Run the drive and adjust WINDAGE LOSS (P.243) until SPD LOOP OUTPUT (P.299)
is zero.
Range: 0.0 to 50.0% P.123 = %
Range: 0.0 to 50.0% P.243 = %
