01/02 AWB8230-1413GB8 TroubleshootingFault Condition Possible cause RemedyThe motor will notstart.The motor turns inthe wrong direction.The motor will notstart.There is voltagepresent at outputs U,V <strong>and</strong> W.There is voltagepresent at outputs U,V <strong>and</strong> W.Is voltage applied to terminalsL1terminals L1, L2<strong>and</strong> L3?If yes, is the ON lamp lit?Does the LED display on the keypad indicate afault (E……) an?Has a start signal been issued?Has a frequency setpoint value been enteredunder PNU F001 (keypad operation only)?Are the setpoint definitions through thepotentiometer correctly wired to terminals H, O<strong>and</strong> L?Are inputs O, , O2 <strong>and</strong>/or OI correctly connectedfor external setpoint definition?Are the digital inputs configured as RST or FRSstill active?Has the correct source for the frequency setpoint(PNU A001) been set?Has the correct source for the start <strong>com</strong>m<strong>and</strong>(PNU A002) been set?Is the motor blocked or is the motor load toohigh?– Are output terminals U, V <strong>and</strong> W correctlyconnected? Does the connection of terminals U, V<strong>and</strong> W correspond with the direction of rotationof the motor?Are the control signal terminals correctly wired?Has PNU F004 been configured correctly?– A setpoint value is not present on terminal O O,O2 <strong>and</strong>/or OI.Is a fixed frequency accessed?Is the motor load too high?Check terminals L1, L2, L3 <strong>and</strong> U, V, W. Switchon the supply voltage.Analyze the cause of the fault signal (a section“Messages”, page 151). Acknowledge the faultmessage with the reset <strong>com</strong>m<strong>and</strong> (e.g. bypressing the OFF key).Issue the start signal with the ON key or throughthe FWD/REV input.Enter a frequency setpoint value underPNU F001.Check that the setpoint signal is correctlyconnected.Check that the setpoint signal is correctlyconnected.Deactivate RST <strong>and</strong>/or FRS.Check the signal on digital input 1 (defaultsetting: RST).Correct PNU A01.Correct PNU A02. (a section “Setting thefrequency <strong>and</strong> start signal parameters”,page 107)Reduce the load acting on the motor. Test themotor without load.Connect output terminals U, V <strong>and</strong> W correctly tothe motor according to the required direction ofmotor rotation (generally the sequence U, V, Wcauses clockwise operation).Use control signal terminal FW(D) for clockwiserotation, REV for anticlockwise rotation.Under PNU F004, enter the required direction ofrotation.Check the potentiometer or the external setpointgenerator <strong>and</strong> replace if necessary.Observe the sequence of priority: the fixedfrequencies always have priority over the inputsO, O2 <strong>and</strong> OI.Reduce the motor load as the overload limit willprevent the motor reaching its normal speed ifthere is an overload.157
