VLT ® 2800 Series- overruled to stop with subsequent trip [5]319 Analogue output terminal 42(AO 42 FUNCTION)Value:No function (NO OPERATION) [0]External reference min.-max. 0-20 mA(REF MIN-MAX = 0-20 MA) [1]External reference min.-max. 4-20 mA(REF MIN-MAX = 4-20 MA) [2]Feedback min.-max. 0-20 mA(FB MIN-MAX = 0-20 MA) [3]Feedback min.-max. 4-20 mA(FB MIN-MAX = 4-20 MA) [4]Output frequency 0-max 0-20 mA(0-FMAX = 0-20 MA) [5]Output frequency 0-max 4-20 mA(0-FMAX = 4-20 MA) [6]✭Output current 0-I INV 0-20 mA(0-IINV = 0-20 MA) [7]Output current 0-I IINV 4-20 mA(0-IINV = 4-20 MA) [8]Output power 0-P M,N 0-20 mA(0-PNOM = 0-20 MA) [9]Output power 0-P M,N 4-20 mA(0-PNOM = 4-20 MA) [10]Inverter temperature 20-100 °C 0-20 mA(TEMP 20-100 C=0-20 MA) [11]Inverter temperature 20-100 °C 4-20 mA(TEMP 20-100 C=4-20 MA) [12]Function:The analogue output can be used for stating aprocess value. It is possible to choose two typesof output signals 0 - 20 mA or 4 - 20 mA.If used as a voltage output (0 - 10 V), a pull-downresistor of 500 must be fitted to common(terminal 55). If the output is used as a currentoutput the resulting resistance from the equipmentconnected may not exceed 500 .Description of choice:No function. Is selected if the analogueoutput is not to be used.External Ref MIN - Ref MAX 0-20 mA/4-20 mA.An output signal is obtained, which is proportionalto the resulting reference value in the intervalMinimum reference, Ref MIN - Maximum reference,Ref MAX (parameters 204/205).FB MIN -FB MAX 0-20 mA/ 4-20 mA.An output signal is obtained, which is proportional to thefeedback value in the interval Minimum feedback, FB MIN- Maximum feedback, FB MAX (parameter 414/415).0-f MAX 0-20 mA/4-20 mA.An output signal is obtained, which is proportional tothe output frequency in the interval 0 - f MAX (parameter202 Output frequency, high limit, fMAX).0 - I INV 0-20 mA/4-20 mA.An output signal is obtained, which is proportionalto the output current in the interval 0 - I INV0 - P M,N 0-20 mA/4-20 mA.An output signal is obtained, which is proportional tothe present output power. 20 mA corresponds to thevalue set in parameter 102 Motor power, P M,N .✭ = factory setting.
