If AccelerationRateSelector (02.010) = 9 the acceleration rate is selected based on the value of PresetSelectedIndicator (01.050), i.e. 1 selects
AccelerationRate1 (02.011), 2 selects AccelerationRate2 (02.012), etc.

See RampRateUnits (02.039) for the definition of Ramp rate frequency.
AccelerationRate1 (02.011) - AccelerationRate8 (02.018) can be selected to define the linear ramp rate. The acceleration rate applies when the
frequency is changing away from zero.
Selecting a ramp rate that has been set to zero in Asynchronous mode disables the ramp system so that the PostRampReference (02.001) follows
the Pre-rampReference (01.003) without any delay for acceleration or deceleration. It should be noted that this also disables the standard ramp d.c. link
voltage controller and the frequency based current limits.
