6-25 Terminal 54 High Ref./Feedb. ValueRange: Function:100.000 N/A*[-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the high voltage/high current value set inpar. 6-21Terminal 54 High Voltage and par. 6-23Terminal 54 High Current.6-26 Terminal 54 Filter Time ConstantRange: Function:0.001 s* [0.001 - 10.000 s] Enter the time constant. This is a first-order digital low pass filter time constant for suppressingelectrical noise in terminal 54. A high time constant value improves dampening but also increasesthe time delay through the filter.This parameter cannot be adjusted while the motor is running.6-27 Terminal 54 Live ZeroOption: Function:This parameter makes it possible to disable the Live Zero monitoring. E.g. to be used if the analogoutputs are used as part of a de-central I/O system (e.g. when not as part of any frequency con-verter related control functions, but feeding a Building Management System with data).[0] Disabled[1] * Enabled6-50 Terminal 42 OutputOption: Function:Select the function of Terminal 42 as an analog current output. A motor current of 20 mA corre-sponds to Imax.[0] * No operation[100] Output freq. 0-100 0 - 100 Hz, (0-20 mA)[101] Reference Min-Max Minimum reference - Maximum reference, (0-20 mA)[102] Feedback +-200% -200% to +200% of par. 20-14Maximum Reference/Feedb., (0-20 mA)[103] Motor cur. 0-Imax 0 - Inverter Max.
