3.5 Main Menu - Limits/Warnings - Group 43.5.1 4-1* Motor LimitsDefine current and speed limits for the motor, and thereaction of the adjustable frequency drive when the limitsare exceeded.4-10 Motor Speed DirectionOption: Function:[0] Clockwise Only operation in a clockwise direction willbe allowed.[2] Both directions Operation in both a clockwise and counter-clockwise direction will be allowed.NOTE!The setting in 4-10 Motor Speed Direction has impact on1-73 Flying Start.4-12 Motor Speed Low Limit [Hz]Range: Function:0 Hz* [ 0 - 400.0Hz]Enter the minimum limit for motor speed.The Motor Speed Low Limit can be set tocorrespond to the minimum outputfrequency of the motor shaft. The SpeedLow Limit must not exceed the setting in4-14 Motor Speed High Limit [Hz].4-14 Motor Speed High Limit [Hz]Range: Function:65 Hz* [ 0.1 -400.0 Hz]Enter the maximum limit for motor speed.4-14 Motor Speed High Limit [Hz] can be setto match the manufacturer's recommendedmax. motor speed. The Motor Speed HighLimit must exceed the value in 4-12 MotorSpeed Low Limit [Hz].NOTE!Max. output frequency cannot exceed 10% of the inverterswitching frequency (14-01 Switching Frequency).NOTE!Motor Speed High Limit cannot be set higher than4-19 Max Output Frequency.4-18 Current LimitRange: Function:110 %* [0 - 300 %]4-19 Max Output FrequencyRange: Function:Size related* [ 0.0 - 400 Hz]3.5.2 4-4* Adjustable Warnings 24-40 Warning Frequency LowRange: Function:0.00Hz*[0.0 Hz-Depends on thevalue of 4-41WarningFrequency High]Use this parameter to set a lower limitfor the frequency range.When the motor speed falls below thislimit, the display reads SPEED LOW.Warning bit 10 is set in 16-94 Ext.Status Word. Output Relay can beconfigured to indicate this warning.LCP warning light does not light whenthis parameter set limit is reached.4-41 Warning Frequency HighRange: Function:400.0Hz*[Depends onthe value of 4-40WarningFrequency Low -400.0 Hz]Use this parameter to set a higherlimit for the frequency range.When the motor speed exceeds thislimit, the display reads SPEED HIGH.Warning bit 9 is set in 16-94 Ext.Status Word. Output Relay can beconfigured to indicate this warning.LCP warning light does not lightwhen this parameter set limit isreached.3.5.3 4-5* Adj. WarningsDefine adjustable warning limits for current. Warnings areshown on the display, programmed output or serial bus.4-50 Warning Current LowRange: Function:0 A* [ 0 - 194.0A]Enter the ILOW value. When the motor currentfalls below this limit, a bit in the drive's statusword will be set. This value can also beprogrammed to produce a signal on thedigital output or the relay output.4-51 Warning Current HighRange: Function:Sizerelated*[ 0.0 -194.0 A]Enter the IHIGH value. When the motorcurrent exceeds this limit, a bit in thedrive's status word will be set. Thisvalue can also be programmed toproduce a signal on the digital outputor the relay output.Parameters VLT® HVAC Basic Drive Programming GuideMG18B222 - VLT® is a registered Danfoss trademark 3-173 3
