The acceleration is reduced in all spindle modes above the speed defined in MD 2471* -
2478*. The degree of weakening can be set with the matching factor MD 2479* - 2486*.
The machine data has no effect is zero or a value above the maximum speed is entered.
The unit is defined as 0.1 or 1 rpm in MD 5200, bit 3.
