Overload current Armaturecurrentthatispermissibleduringtheoverloadtime(setwithOverload time).
Itisalways200%asamaximumoftheactivecurrentat Full load currandtherefore
proportionaltothetorque.
Base current Armaturecurrentthatispermissibleduringthepausetime(setwithPausetime).The
percentagereferstotheactivecurrentatFull load curr.
Overload time MaximumtimeinwhichtheOverload currentispermissible.
Ventil. Type AUTO Autofanindicatesthepresenceofafanunitmountedonthe
motorshaftthatthereforeturnsataspeedpropor-tionaltothe
motorspeed.Coolingisnotveryeffectiveatlowmotorspeeds.
 SERVO Servofanindicatesthepresenceofanindependentfanunitthat
thereforealwaysrunsattheratedspeed.Iten-suresoptimum
coolingefciencyatallmotorspeeds.
note !  Themanagementofmotorcontroloverloadwithauto-ventilatedmotorhastheaimofgen-
eratingamotorOverloadalarmbeforethethreshold(conguredbytheparameters310
Overload timeand312Overload current isreached)whenthemotorspeedislessthan
halfofthenominal.
 ItisalsoimplementedtosavetheinternalI2taccumulatorofthedriveandmotoratthepower
off.Inthisway,atthepowerontheparametervalue655(Motor I2t accum)and1439(Drive
I2t accum)willbeequaltothepresentvalueatthetimeofthepreviouspoweroff.
Derating factor ThisparameterisusedtosetthederatingfactorforAutofanmotorandrepresentsthe
continuousoutputcurrentvalueatzerospeedexpressedaspercentageofthefullload
current.Whenmotorspeedisbelow50%ofnominalvaluethecontinuousoutputcur-
rentislinearlydecreasedfrom100%offullloadcurrenttothisvalue.
