This parameter is used to select deceleration ramp rates as follows:
0 Ramp rate selection by terminal input
1 Ramp rate 1 selected
2 Ramp rate 2 selected
3 Ramp rate 3 selected
4 Ramp rate 4 selected
5 Ramp rate 5 selected
6 Ramp rate 6 selected
7 Ramp rate 7 selected
8 Ramp rate 8 selected
9 Ramp rate selection by preset reference selection
When 2.20 is set to 0 the deceleration ramp rate selected depends on the state of bit parameters 2.35, 2.36 & 2.37. These
bits are for control by digital inputs such that ramp rates can be selected by external control. The ramp rate selected depends
on the binary code generated by these bits as follows:
When 2.20 is set to 9 the appropriate deceleration rate is automatically selected depending on the preset reference selected.
Thus an deceleration rate can be programmed to operate with each preset reference. Since the new ramp rate is selected
with the new reference, the deceleration applies towards the selected preset.
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. the preset speed being decelerated to.
Although the deceleration rate can be set to 0.0, there is a minimum ramp time within the software of 0.1s/100Hz.
