5.3.5.3 Field converter
ThedefaultTPD32 -EV convertersaresettooperatewithoutVoltagecontrol.Thefollowingsettingsmustbetaken
intoconsiderationwhenafunctioninginVoltagecontrolisneededorwhentheeldoftheconnectedmotoris
notpowersuppliedviatheconverter.
Allthesettingsdescribedinthischaptermustbecarriedoutindisablecondition(novoltageonterminal12).
Selection of the functioning system
- Withaconstanteldcurrent:  Flux reg mode =Constantcurrent
Enable ux reg=Enabled
- WithVoltagecontrol:  Flux reg mode=Voltagecontrol.

Setting the rated field current
- SettheratedeldcurrentofthemotorviatheMotor nom ux parameter.
