The ‘Parameter set’ ‘Custom’ enables individual adjustment/optimisation of the control response
for an application. This adjustment enables greater pressure dynamics in the face of a constriction
compared to a standard controller. This considerably reduces settling times for pressure jumps. The
two required model parameters (‘Tuning parameter pressure increasing’/‘Tuning parameter pressure
decreasing’) can be determined automatically via homing. The determined model parameters can also
be manually adjusted later. Free input of the two model parameters without homing is also possible.
