Mountain, the inching mode in the ABB drives are currently set to turn the SAG mill at about 10 % of rated speed and the ball mills at about 3% of rated speed (mill speed 0.40 rpm). Furthermore tests during the hot commissioning have shown that the drives can even operate in inching mode at as little as 1% rated speed (mill speed 0.10 rpm).
