22-47 Sleep Speed [Hz]Range: Function:0 * [ 0 - 400.0 ] Set the speed below which the frequencyconverter will go into Sleep Mode.3.15.2 22-6* Broken Belt DetectionThe Broken Belt Detection can be used in both closed andopen loop systems for pumps and fans. If the estimatedmotor torque (current) is below the broken belt torque(current) value (22-61 Broken Belt Torque) and thefrequency converter output frequency is above or equal to15 Hz, 22-60 Broken Belt Function is performed22-60 Broken Belt FunctionOption: Function:Select the actions to be performed if the brokenbelt condition is detected.[0] Off[1] Warning The frequency converter will continue to run, butactivates a broken belt warning [W95]. A frequencyconverter digital output or a serial communicationbus can communicates a warning to otherequipment.[2] Trip The frequency converter will stop running andactivate a broken belt alarm [A95]. A frequencyconverter digital output or a serial communicationbus can communicate an alarm to otherequipment.22-61 Broken Belt TorqueRange: Function:10 %* [5 - 100 %] Sets the broken belt torque as a percentageof the rated motor torque.22-62 Broken Belt DelayRange: Function:10 s* [0 - 600 s] Sets the time for which the broken beltconditions must be active before carrying outthe action selected in 22-60 Broken BeltFunction.3.16 Parameters: 30-** Special Features30-83 Speed PID Proportional GainRange: Function:Size related* [0 - 1 ] Enter the speed controller proportionalgain. Quick control is obtained at highamplification. However, if amplification istoo great, the process may becomeunstable.Parameter Descriptions VLT® AutomationDrive FC 360 Programming GuideMG06C102 - VLT® is a registered Danfoss trademark 813 3
