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.

Acceleration Rate 1 (02.011) to Acceleration Rate 8 (02.018) can be selected to define the linear ramp rate. The acceleration rate applies when the
frequency/speed is changing away from zero.
Selecting a ramp rate that has been set to zero in Open-loop 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.
The units of Acceleration Rate 1 (02.011) to Acceleration Rate 8 (02.018) are s / Ramp rate frequency or s / Ramp rate speed. See Ramp Rate Units
(02.039) for the definition of Ramp rate frequency and Ramp rate speed.
