3.24.3 26-2* Analog Input X42/3Parameters for configuring the scaling and limits for analoginput, terminal X42/3.26-20 Terminal X42/3 Low VoltageRange: Function:0.07 V* [ 0 - par. 6-31V]Enter the low voltage value. Thisanalog input scaling value shouldcorrespond to the low reference/feedback value set inparameter 26-24 Term. X42/3 LowRef./Feedb. Value.26-21 Terminal X42/3 High VoltageRange: Function:10 V* [ par. 6-30 -10 V]Enter the high-voltage value. Thisanalog input scaling value shouldcorrespond to the high reference/feedback value set inparameter 26-25 Term. X42/3 HighRef./Feedb. Value.26-24 Term. X42/3 Low Ref./Feedb. ValueRange: Function:0* [-999999.999- 999999.999 ]Enter the analog input scaling valuethat corresponds to the low-voltagevalue set inparameter 26-20 Terminal X42/3 LowVoltage.26-25 Term. X42/3 High Ref./Feedb. ValueRange: Function:100* [-999999.999- 999999.999 ]Enter the analog input scaling valuethat corresponds to the high-voltage value set inparameter 26-21 Terminal X42/3 HighVoltage.26-26 Term. X42/3 Filter Time ConstantRange: Function:0.005 s* [0.005 - 10 s] NOTICEThis parameter cannot beadjusted while the motor isrunning.Enter the time constant. This is afirst-order digital low-pass filtertime constant for suppressing noisein terminal X42/3. A high timeconstant value improvesdampening, but also increases thetime delay through the filter.26-27 Term. X42/3 Live ZeroOption: Function:This parameter makes it possible toenable the live zero monitoring, forexample, where the analog input isthe frequency converter control,rather than being used as adecentral I/O system, such as abuilding management system.[0] Disabled[1] * Enabled3.24.4 26-3* Analog Input X42/5Parameters for configuring the scaling and limits for analoginput, terminal X42/5.26-30 Terminal X42/5 Low VoltageRange: Function:0.07 V* [ 0 - par. 6-31V]Enter the low-voltage value.
