VLT® 5000 Crane■ Crane Functions■ Introduction to Crane ParametersThis parameter group contains all the crane specificparameters making the VLT 5000 Crane standout from other VLT products.It is important to notice that theseparameters only should be handled byskilled personnel as wrong handlingmay cause serious accidents!701 LOAD LOWValue:0 - 5000 RPM ✭ Depends on unitFunction:The values for Load Low are set in this parameterin RPM. If the speed set for the load contact isexceeded, the frequency converter will trip.Description of choice:The value of parameter 701 may only be higher orequal to the value of parameter 702.702 LOAD HIGHValue:0 - 1250 RPM ✭ Depends on unitFunction:The values for Load High are set in thisparameter in RPM.If the speed set for the load contact is exceeded,the frequency converter will trip.703 LOAD MONITORINGValue:Disable (DISABLE) [0]✭Enable (ENABLE) [1]Function:Load Monitoring of load contacts 1 and 2 can beeither disabled or enabled in this parameter.704 LOW SPD. AT ERRORValue:-200 - 200 RPM ✭ 50 RPMFunction:With this parameter you can choose the loweringspeed at brake fault 1, which is when the systembrake cannot hold the load.705 BRAKE ON RPMValue:5 - 50 RPM ✭ 20 RPMFunction:This parameter allows choosing the min. speed atwhich the system brake signal of relay 1-3 must beremoved (the system brake takes over the load).707 HOIST DIRECTIONValue:✭0 (FORWARD) [0]1 (BACKWARD) [1]Function:In this parameter the direction, in which the motoris to rotate during hoisting, is set.708 START TORQUEValue:0 - 170% ✭ 100%Function:This parameter allows choosing the start torquefor the motor when taking over the load from thesystem brake. Set the start torque in % of therated motor torque set in the software.709 RAMP TORQUEValue:0.0 - 2 SEC ✭ 0.2 SECFunction:With this parameter the build-up time of thestart torque is set.✭ = factory setting.
