Emerson unidrive m200 - S Ramp Set-Up Mode; Maximum Rate of Change of Acceleration 1

Parameter 02.041 S Ramp Set-up Mode
Short description Defines the mode used by the S ramp system

SRampSet-upMode (02.041) defines the method used to set up the S ramp function.
0: Single maximum rate of change of acceleration
The maximum rate of change of acceleration in either direction, when the frequency is changing away from or towards zero, is defined by
MaxRateOfChangeOfAcceleration (02.007).
1: S ramp percentage
A single maximum rate of change of acceleration is used in either direction, when the frequency is changing away from or towards zero, but this is
specified as the percentage of the ramp from zero to Maximum frequency which is covered by the S shaped profile. See SRampPercentage (02.040).
2: Four independent maximum rate of change of acceleration values
The maximum rate of change of acceleration can be specified as four independent values. See MaxRateOfChangeOfAcceleration (02.007).
Parameter 02.042 Maximum Rate Of Change Of Acceleration 1
Short description Defines the 1st maximum rate of change of acceleration used by the S ramp system
Mode Open‑loop
Minimum 0.0 Maximum 300.0

If SRampSet-upMode (02.041) = 2 it is possible to set up four independent maximum rate of change of acceleration values as shown in the diagram
below. The values from 1 to 4 correspond to MaximumRateOfChangeOfAcceleration1 (02.042) to MaximumRateOfChangeOfAcceleration4
(02.045) respectively.
