7.5.8 Kick Start

This parameter makes it possible to tune the kick start voltage level which is ap-
plied for a short time duration, before a normal start ramp is performed. Kick Start
provides enough torque during start, but still ensuring a soft start.
It can be set on any of the predefined voltage levels. For each voltage level there is
a fixed time duration relation (t), which is increasing with the different kick voltage
levels. This function can be useful for applications with high initial friction or having
a need of extra power in the first part of the start, as jammed pumps or conveyor
belts. See table 7.2 and graph in figure 7.19.
