When parameter Pr 2.20 is set to 9 the appropriate deceleration rate is automatically selected depending on the value of parameter Pr 1.50, and so a
deceleration rate can be programmed to operate with each reference. Since the new ramp rate is selected with the new reference, the deceleration
applies towards the selected preset if the motor needs to decelerate to reach the preset.

NOTE
When switching between preset speeds and using the preset deceleration ramps, the deceleration ramp used is the one associated to the target
preset speed, i.e. if switching from preset speed 3 to preset speed 4 deceleration rate 4 would be used.
If enabling and running to a preset speed using the Run Forward and Run Reverse terminals, the preset deceleration ramp used will be the one
associated to the preset speed being run to.

Jog deceleration rate

Default 0.2

The jog deceleration rate is only used when the drive is changing speed because the jog reference has changed or to stop from the jog reference. It
is not used to go from the jog to the run state. This prevents the fast ramps normally used with jog from being used when changing between running
and jogging.
There are eight deceleration rates programmable for normal operation, plus one for jogging. The ramp rates are expressed as a time for a change of
100 Hz on the ramp output, therefore with a programmed ramp time of 5 seconds the ramp output will go from 50 Hz to 0 in 2.5 seconds (depending
on the setting of Pr 2.39).
