NOTEAutomatic reset will also be active for resetting safe stopfunction.14-21 Automatic Restart TimeRange: Function:10.0 s* [0.0 - 600.0 s] Enter the time interval from trip to start ofthe automatic reset function. Thisparameter is active when 14-20 Reset Modeis set to Automatic reset [1] - [13].14-22 Operation ModeOption: Function:Select Initialisation[2] to reset all parametervalues to default.[0] * NormaloperationSelect Normal operation [0] for normaloperation of the frequency converter with themotor in the selected application.[2] Initialisation Select Initialisation [2] to reset all parametervalues to default settings, except for15-03 Power Up's, 15-04 Over Temp's and15-05 Over Volt's. The frequency converter willreset during the next power-up.14-22 Operation Mode will also revert to thedefault setting Normal operation [0].14-27 Action At Inverter FaultOption: Function:Select how the frequency converter should react atinverter fault. Action At Inverter Fault[0] Trip[1] * Warning3.10.4 14-4*Energy OptimisingParameters for adjusting the energy optimisation level inboth Variable Torque (VT) and Automatic Energy Optimi-zation (AEO) mode.Automatic Energy Optimization is only active if 1-03 TorqueCharacteristics, is set for Auto Energy Optim. [3].14-40 VT LevelRange: Function:90 %* [40 - 90%]Enter the level of motor magnetisation at lowspeed. Selection of a low value reduces energyloss in the motor, but also reduces loadcapability.This parameter cannot be adjusted while themotor is running.14-41 AEO Minimum MagnetisationRange: Function:66 %* [40 - 75 %] Enter the minimum allowable magnetisationfor AEO. Selection of a low value reducesenergy loss in the motor, but can also reduceresistance to sudden load changes.3.10.5 14-5* EnvironmentThese parameters help the frequency converter to operateunder special environmental conditions.14-50 RFI FilterOption: Function:[0] Off Select Off [0] only if the frequency converter is fed by anisolated mains source (IT mains).In this mode, the internal RFI filter capacitors betweenchassis and the mains RFI filter circuit are cut-out toreduce the ground capacity currents.[1] * On Select On [1] to ensure that the frequency convertercomplies with EMC standards.14-51 DC-Link Voltage CompensationOption: Function:[0] Off Disables DC Link Compensation.[1] * On Enables DC Link Compensation.14-52 Fan ControlOption: Function:Only valid for the following frequencyconverters: 380-480V, 30-90kW.[0] * Auto[4] Auto Low Temp Env.14-53 Fan MonitorOption: Function:Select which reaction the frequency convertershould take in case a fan fault is detected. (Onlyvalid for some drive sizes.)[0] Disabled[1] * Warning[2] Trip14-55 Output FilterOption: Function:Select wether a output filteris present.[0] * No Filter[1] Sine-Wave Filter[3] Sine-Wave Filter with FeedbackParameters VLT HVAC Basic Drive Programming GuideMG.18.B1.02 - VLT® is a registered Danfoss trademark 593 3
