3.6 Parameters 4-** Limits/Warnings3.6.1 4-1* Motor LimitsDefine torque, current, and speed limits for the motor, andthe reaction of the frequency converter when the limits areexceeded.A limit may generate a message in the display. A warningalways generates a message in the display or on thefieldbus. A monitoring function may initiate a warning or atrip, after which the frequency converter stops andgenerates an alarm message.4-10 Motor Speed DirectionOption: Function:Selects the motor speed direction required.When parameter 1-00 Configuration Mode isset to [3] Closed loop, the parameter defaultis changed to [0] Clockwise. If both directionsare selected, running in counterclockwisedirection cannot be selected from the LCP.[0] * Clockwise[1] Counterclockwise[2] Bothdirections4-11 Motor Speed Low Limit [RPM]Range: Function:Sizerelated*[ 0 - par.4-13RPM]Enter the minimum limit for motor speedin RPM. The motor speed low limit can beset to correspond to the minimum motorspeed recommended by the manufacturer.The motor speed low limit must notexceed the setting inparameter 4-13 Motor Speed High Limit[RPM].4-12 Motor Speed Low Limit [Hz]Range: Function:Sizerelated*[ 0 -par. 4-14Hz]Enter the minimum limit for motor speedin Hz. The motor speed low limit can beset to correspond to the minimum outputfrequency of the motor shaft. The speedlow limit must not exceed the setting inparameter 4-14 Motor Speed High Limit [Hz].4-13 Motor Speed High Limit [RPM]Range: Function:Sizerelated*[ 0 -60000RPM]NOTICEAny changes in parameter 4-13 MotorSpeed High Limit [RPM] reset the valuein parameter 4-53 Warning Speed Highto the value set inparameter 4-13 Motor Speed High Limit[RPM].NOTICEMaximum output frequency cannotexceed 10% of the inverter switchingfrequency (parameter 14-01 SwitchingFrequency).Enter the maximum limit for motor speed inRPM. The motor speed high limit can be setto correspond to the manufacturer’smaximum rated motor. The motor speedhigh limit must exceed the setting inparameter 4-11 Motor Speed Low Limit [RPM].The parameter name appears as eitherparameter 4-11 Motor Speed Low Limit [RPM]or parameter 4-12 Motor Speed Low Limit [Hz],depending on:• The settings of other parameters inthe Main Menu.• Default settings based ongeographical location.4-14 Motor Speed High Limit [Hz]Range: Function:Sizerelated*[ .1 -par.4-19Hz]Enter the maximum limit for motor speed inHz. Parameter 4-14 Motor Speed High Limit[Hz] can be set to correspond to themanufacturer's recommended maximummotor speed. The motor speed high limitmust exceed the value inparameter 4-12 Motor Speed Low Limit [Hz].The output frequency must not exceed 10%of the switching frequency(parameter 14-01 Switching Frequency).Parameter Description VLT® AQUA Drive FC 20272 Danfoss A/S © 05/2018 All rights reserved.
