Thefollowingequationgivestherelationbetweensynchronousspeed,frequency,andthenumberofpoles:
Ss=120f/p
Where: Ss= Synchronousspeed(rpm) f= frequency(Hz) p= numberofpoles
Inthreephaseinductionmotorstheactualshaftspeeddiffersfromthesynchronousspeedasloadisapplied .Thisdifferenceisknownas“slip” .Slipiscommonlyexpressedasapercentageofsynchronousspeed .Atypicalvalueisthreepercentatfullload .
Thestrengthofthemagneticfieldinthegapbetweentherotorandstatorisproportionaltotheamplitudeofthevoltageatagivenfrequency .Theoutputtorquecapabilityofthemotor is, therefore,a functionof theappliedvoltageamplitudeatagiven frequency .Whenoperatedbelowbase (rated) speed,ACmotors run in the rangeof “constanttorque” .Constant torqueoutput is obtainedbymaintaininga constant ratiobetweenvoltageamplitude(Volts)andfrequency(Hertz) .For60Hzmotorsratedat230,460,and575Vac,commonvaluesforthisV/Hzratioare3 .83,7 .66,and9 .58respectively .OperatingwiththeseV/Hzratiosgenerallyyieldsoptimumtorquecapability .Operatingatlowerratiovaluesresultsinlowertorqueandpowercapability .Operatingathigherratiovalueswillcausethemotortooverheat .Moststandardmotorsarecapableofprovidingfulltorqueoutputfrom3to60Hz .However,atlowerspeeds,wheremotorcoolingfansbecomelesseffective,supplementalcoolingmaybeneededtooperateat full torqueoutputcontinuously .
Ifthefrequencyappliedtothemotorisincreasedwhilethevoltageremainsconstant,torque capability will decrease as speed increases . This will cause the horsepowercapabilityofthemotortoremainapproximatelyconstant .Motorsruninthismodewhenoperated above base speed, where drive output voltage is limited by the input linevoltage .Thisoperatingrangeisknownasthe“constanthorsepower”range .Thetypicalmaximumrangeforconstanthorsepowerisabout2 .3to1(60to140Hz) .ThediagrambelowdepictsthecharacteristicsofatypicalACinductionmotorwitha60Hzbasespeed .

RUN Drive is in RUN mode and is within + 0.3 Hz of the speed setpoint.
FAULTDrive has shut down due to a FAULT condition. If the fault condition has passed, pressing the STOP key will clear the fault and return thedrive to the STOP mode.
LOCK Drive is in FAULT LOCKOUT after five unsuccessful restart attempts.
BRAKE DC BRAKE is energized.
LIMIT Drive is in CURRENT LIMIT due to an overloaded motor, or ACCEL is set too fast.
F DEC Drive is in DECEL FREEZE because DECEL is set too fast.

17 MOTOROL (MOTOROVERLOAD)
TheMC3000SeriesisULapprovedforsolidstatemotoroverloadprotection .Therefore,a separate thermal overload relay is not required for single motor applications . TheMOTOR OVERLOAD circuit is used to protect the motor from overheating due toexcessivecurrentdraw .
The trip time for theMOTOROVERLOAD isbasedonan “inverse I2t” function .Thisfunctionallowsthedrivetodeliver150%oftheratedoutputcurrentforoneminute,andevenhighercurrentlevelsforshorterperiodsoftime .Oncetheoverloadcircuit“timesout”,thedrivewilltripintoanOVERLOADfault .
The MOTOR OVERLOAD should be set to a value which is equal to the ratio (inpercentage)ofthemotorfullloadcurrentratingtothedriveoutputcurrentrating .Thiswillresultinanoverloadcapacityof150%oftheMOTORcurrentratingforoneminute .Ifthisparameterissetto100%,themotorwillbeallowedtodraw150%oftheDRIVEoutputcurrentratingforoneminute .Thisdistinctionisimportantincaseswherethemotorfullloadcurrentratingissignificantlylessthanthedriveoutputcurrentrating,suchasapplicationswherethedriveisoversizedtomeettorquerequirements .
Example1:A5Hp,480Vacdriveisoperatinga3HPmotorwithafull loadcurrentratingof4 .8amps .Dividethemotorcurrentratingbythedriveoutputcurrentrating:4 .8/7 .6=63% .Enteringthisvaluewillallowcontinuousoperationat4 .8amps,andwillalsoallowthemotortodraw7 .2amps(150%of4 .8amps)foroneminute .Ifthesettingisleftat100%,themotorcoulddraw11 .4amps(150%of7 .6amps)foroneminutebeforefaulting .

NOTE1: The above diagram is based on a MOTOR OL setting of 100% . ForlowerMOTOROLsettings,reducethe%CURRENTvaluesbythesamepercentage . For example, if MOTOR OL is set to 75%, reduce the %CURRENTvaluesby25% .Therefore,thecurveshiftsdown,buttheshapeofthecurveremainsthesame .
The“non-compensated”thermaloverloadcircuitallows100%currentcontinuously,and150%currentforoneminute,atallspeeds .Intheexampleabove,themotoroperatingat10Hzwithout“speed-compensated”protectionwouldbeallowedtooperatecontinuouslyat27Amps,andcoulddraw40 .5Ampsforoneminutebeforetripping .Withoutsufficientmotorcooling,thiscanresultinmotorfailureduetooverheating .

FAULT MESSAGES
FAULT DESCRIPTION POSSIBLE CAUSES
OUTPUT Output transistor fault:Output current exceeded 200% of drive rating
Phase to ground short.Phase to phase short.FX BOOST set too high.Bad transistor module (IPM).
LO VOLTS Low DC Bus Voltage fault:DC bus voltage below 60% of normal.
Low line voltage.
HI VOLTS High DC Bus Voltage fault:DC bus voltage above 120% of normal.
High line voltage.Overhauling load.DECEL rate is set too fast.
HI TEMP Temperature fault:Internal drive temperature too high.
Ambient temperature too high.Fan failure (if equipped).
OVERLOAD Current Overload fault:Output current rating exceeded for too long.
Drive undersized for theapplication.Problem with motor and/or driven equipment.
PWR TRAN Power Transient fault:Low line voltage.
AC line dipped or sagged.
PWR SAG Power Sag fault:Control board voltage is below tolerance.A new control board has been installed that is different from the previous version.
Erratic AC line.Perform a factory reset usingParameter 65-PROGRAM.This will update the softwareand allow the fault to be reset.
LANGUAGE Language fault:Selected language not present
Defective language EEPROM.Language EEPROM (U11)removed after programming.
EXTERNAL External fault:TB-13D is open or closed to TB-2, depending on setting of Parameter 50 - TB13D.
Check setting of Parameter 50.Check devices wired between TB13D and TB-2.
DB ERROR Dynamic Brake fault:DB circuit has sensed a resistor overload.
The DB duty cycle is too high, causing the resistors to overheat.
