3.6.2 4-5* Adj. WarningsDefine adjustable warning limits for current, speed,reference, and feedback.NOTICENot visible in the display, only in MCT 10 Set-upSoftware.4-50 Warning Current LowRange: Function:0 A* [ 0 - par. 4-51A]Warnings are shown on the display,programmed output, or fieldbus.130BA064.10(P 4-18)(P 4-51)(P 4-50)(P 4-11) (P 4-53)(P 4-52) (P 4-13)IHIGHILOWnLOW nHIGHnmotorImotorREFON REFIN RANGEI LIMnMAXnMIN[RPM]Illustration 3.25 Low CurrentLimitEnter the ILOW value. When themotor current drops below thislimit (ILOW), the display reads Currentlow. The signal outputs can beprogrammed to produce a statussignal on terminal 27 or 29, and onrelay output 01 or 02. Refer toIllustration 3.25.4-51 Warning Current HighRange: Function:Sizerelated*[ par. 4-50 -par. 16-37 A]Enter the IHIGH value. When themotor current exceeds this limit(IHIGH), the display reads Currenthigh. The signal outputs can beprogrammed to produce a statussignal on terminal 27 or 29, and onrelay output 01 or 02. Refer toIllustration 3.25.4-52 Warning Speed LowRange: Function:0 RPM* [ 0 - par. 4-53RPM]Enter the nLOW value. When themotor speed exceeds this limit, thedisplay reads Speed low.4-53 Warning Speed HighRange: Function:Sizerelated*[ par. 4-52 -60000 RPM]NOTICEAny changes inparameter 4-13 Motor SpeedHigh Limit [RPM] reset thevalue inparameter 4-53 Warning SpeedHigh to the same value as setin parameter 4-13 Motor SpeedHigh Limit [RPM].If a different value is neededin parameter 4-53 WarningSpeed High, it must be setafter programming ofparameter 4-13 Motor SpeedHigh Limit [RPM].Enter the nHIGH value. When themotor speed exceeds this limit(nHIGH), the display reads Speed high.The signal outputs can beprogrammed to produce a statussignal on terminal 27 or 29, and onrelay output 01 or 02. Program theupper signal limit of the motorspeed, nHIGH, within the normalworking range of the frequencyconverter. Refer to Illustration 3.25.4-54 Warning Reference LowRange: Function:-999999.999*[ -999999.999- par. 4-55 ]Enter the lower reference limit.When the actual reference dropsbelow this limit, the display showsRefLow. The signal outputs can beprogrammed to produce a statussignal on terminal 27 or 29, and onrelay output 01 or 02.4-55 Warning Reference HighRange: Function:999999.999*[ par. 4-54 -999999.999 ]Enter the upper reference limit.When the actual reference exceedsthis limit, the display reads RefHigh.The signal outputs can beprogrammed to produce a statussignal on terminal 27 or 29, and onrelay output 01 or 02.Parameter Descriptions Programming GuideM0010001 Danfoss A/S © 10/2019 All rights reserved. 833 3
