• Field circuit
TheTPD32-EVregulationcardisshippedwiththeeldcurrentfeedbackresistordipswitchesS14calibrated
forthemaximumratingoftheeldpackagecapacityforeachsizeTPD32-EV.
ComparetheactualmotorelddatatothemaximumratingoftheeldpackageoftheTPD32-EVmodelsup-

Calibrationtotheexacteldcurrentsettingisnotrequired,aslongastheaboveconditionsaremet.
Calibrationisnotrequirediftheeldcontrolisprovidedbyaseparateeldconverter.
Inordertoobtainacurrentsettingvaluedifferentfromthosestatedinthetable,usethefollowingformulasto
calculatetheresistancetobeusedbetweentheterminalsLAandLBontheregulationcard.Inthiscaseallthe
switcheshavetobesettozero(OFF).
1) For sizes TPD32-EV-.../...-20-..-A (17-NA-..-A) ... up to TPD32-EV-.../...-1050-..-C (850-NA-..-C) :
Resistance = 1667 / eld current (A).
