 +The determination of the cycle time calculation is part of the [[..:eingabe_der_verfahrensparameter:eingabe_der_verfahrensparameter|process parameters]].

 +
 +Via the drop-down selection, four different options for determining the cycle time are provided.
 +
 +In general, the following applies:
 +
 +$$t_{cycle}=t_{plasticizing}+t_{downtime}$$
 +
 +The downtime therefore also includes, among others, the injection time and the holding pressure time. Thus, the following condition must hold:
 +
 +$$t_{downtime} \geq t_{injection} + t_{holding}$$

 +==== Screw speed is calculated, times are specified ====
 +In this mode, the three fields must be defined:
 +  * Cycle time
 +  * Plasticizing time
 +  * Downtime
 +
 +Any two values can be entered; the third is calculated automatically.
 +From the [[..:eingabe_der_verfahrensparameter:eingabe_der_verfahrensparameter|shot volume]] (mandatory input) and the plasticizing time, the mass throughput is determined. The screw speed required to achieve this throughput is then calculated by PSI.

 +==== Screw speed is calculated, throughput is specified ==== 
 +In this mode, the two fields must be defined:
 +  * Downtime
 +  * Throughput
 +
 +From the throughput and the [[..:eingabe_der_verfahrensparameter:eingabe_der_verfahrensparameter|shot volume]] (mandatory input), the plasticizing time is derived, and therefore also the cycle time. The screw speed required to achieve the specified mass throughput is calculated by PSI.
 +
 +==== Screw speed and cycle time are specified ==== 
 +In this mode, the two fields must be defined:
 +  * Screw speed
 +  * Cycle time
 +
 +Based on the screw speed, the mass throughput is calculated (this can also be entered directly as an option). From the mass throughput and the [[..:eingabe_der_verfahrensparameter:eingabe_der_verfahrensparameter|shot volume]] (mandatory input), the plasticizing time is determined, and thus the downtime is also known.
