Deceleration Rate 1 (02.021) to Deceleration Rate 8 (02.028) can be selected to define the linear ramp rate. The deceleration rate applies when the
frequency/speed is changing towards 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 thePre-
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 Deceleration Rate 1 (02.021) to Deceleration Rate 8 (02.028) 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.
