6.4 INPUT VARIABLES
TheconvertersoftheTPD32-EVseriesenablereferencevaluesfortherampandregulatortobespeciedin
differentdimensions:
- asapercentageoftheSpeed base value
- inadimensionthattheusercandenehimselfwiththefactor-function,i.eg.asaspeedm/s.Thedefault
factorysettingisrpm.
Thevalueprocessesinsidethedeviceisthesameirrespectiveofhowitwasdened.Thismeansthattheother
referenceisoverwrittenwiththenewvalue.
Example:
Amotorhasamaximumspeedof1500rpm.Thiscorrespondsto100%andatthesametimetheuser-dened
valueof10,000bottlesperhour(see6.11.7).
Changingthereferencevalueto50%willautomaticallyresultinachangeoftheothervalueto5,000bottlesperhour.
Thetablebelowshowstherelationshipofreferencevalues.Intheeventofachange,theotherparametersare
overwrittenautomatically.

Therampreferencevaluespeciesthespeedthedriveshouldreachoncetheaccelerationphasehasbeencom-
pleted.Modicationstotherampreferencevaluearethereforetransferredtotherampaccordingly.Theheight
oftherampreferencevaluedeterminesthemotorspeed.Asforthefourquadrantdrives(TPD32-EV...4B...)the
rotationdirectionisdeterminedbythereferencepolarity.
note!  TwoquadrantTPD32-EV...2B...drivesacceptonlypositivereferences.Negativevaluesare
notconsidered!
