Parameters A - 32Reference DetectionL4-01Speed AgreementDetection LevelSpd Agree LevelThese parameters configure the multi-function output (H2-)settings “Fref/Fout agree 1”, “Fref/Set agree 1”, “Frequencydetection 1,” and “Frequency detection 2". Parameter L4-01 sets thelevel while parameter L4-02 sets the hysteresis for the speed detec-tion output function.VariesbyDutyRating* 10.0Hz A A A AL4-02Speed AgreementDetection WidthSpd Agree Width0.0 to20.0 2.0Hz A A A AL4-03Speed AgreementDetection Level (+/-)Spd Agree Lvl +-These parameters configure the multi-function output (H2-)settings “Fref/Fout agree 2”, “Fref/Set agree 2”,“Frequency detection 3,” or “Frequency detection 4".

The frequency reference is considered lost when referencedrops 90% or more of its current value in less than 400ms.0: Stop - Drive will stop.1: Run at L4-06 PrevRef - Drive will run at the percentage set inL4-06 of the frequency reference level at the time frequencyreference was lost.0 to 1 0 A A A AL4-06Frequency Reference Level atLoss FrequencyFref at FlossIf the frequency reference loss function is enabled (L4-05=1) andfrequency reference is lost, the Drive will run at a reducedfrequency reference determined by the following formula:Fref = Fref at time of loss * L4-06.0 to 100.0 80.0% A A A AFault RestartL5-01Number of Auto RestartAttemptsNum of RestartsSets the counter for the number of times the Drive will perform anautomatic restart on the following faults: GF, LF, OC, OV, PF, PUF,RH, RR, OL1, OL2, OL3, OL4, UV1. Auto restart will check to seeif the fault has cleared every 5ms. When no fault is present, theDrive will attempt an auto restart. If the Drive faults after an autorestart attempt, the counter is incremented. When the Driveoperates without fault for 10 minutes, the counter will reset to thevalue set in L5-01.0 to 10 0 A A A AL5-02Auto Restart Operation Selec-tionRestart SelDetermines if the fault contact activates during an automatic restartattempt.0: No Fault Relay - fault contact will not activate during anautomatic restart attempt.1: Fault Relay Active - fault contact will activate during anautomatic restart attempt.0 to 1 0 A A A ATorque DetectionL6-01Torque DetectionSelection 1Torq Det 1 SelDetermines the Drive's response to an Overtorque/Undertorquecondition. Overtorque and Undertorque are determined by thesettings in parameters L6-02 and L6-03. The multi-function outputsettings “B” and “17” in the H2- parameter group are alsoactive if programmed.0: Disabled1: OL3 at Speed Agree - Alarm (Overtorque Detection only activeduring Speed Agree and Operation continues after detection).2: OL3 at RUN - Alarm (Overtorque Detection is always active andoperation continues after detection).3: OL3 at Speed Agree - Fault (Overtorque Detection only activeduring Speed Agree and Drive output will shut down on an OL3fault).4: OL3 at RUN - Fault (Overtorque Detection is always active andDrive output will shut down on an OL3 fault).5: UL3 at Speed Agree - Alarm (Undertorque Detection is onlyactive during Speed Agree and operation continues afterdetection).6: UL3 at RUN - Alarm (Undertorque Detection is always activeand operation continues after detection).7: UL3 at Speed Agree - Fault (Undertorque Detection only activeduring Speed Agree and Drive output will shut down on an OL3fault).8: UL3 at RUN - Fault (Undertorque Detection is always active andDrive output will shut down on an OL3 fault).0 to 8 0 A A A ADenotes that parameter can be changed when the Drive is running.*1 For Heavy Duty (HD) Rating: Setting Range=0.0 to 300.0.
