If S-ramps are selected, set the level of non-linear jerk compensation required. Set jerk compensation by defining the proportion of
ramp-up and ramp-down times where acceleration and deceleration are variable (that is, increasing or decreasing). The S-ramp ac-
celeration and deceleration settings are defined as a percentage of the actual ramp time.

A digital impulse triggers the emergency mode operation with stop on all alarms as option [2] Trip, all alarms/test in parameter 24-09
Emergency Mode Alarms Handling. This test impulse signal can only activate 1 test time period and the normal emergency mode
operation takes over as soon as the test time ends, or it stops the test period if the emergency mode signal disappears. Only "normal
