6-22 Terminal 54 Low CurrentRange: Function:4 mA * [0.0 to par. 6-23 mA] Enter the low current value. This reference signal should corre-spond to the low reference/feedback value, set in par. 6-24. Thevalue must be set at >2 mA in order to activate the Live ZeroTime-out Function in par. 6-01.6-23 Terminal 54 High CurrentRange: Function:20.0mA *[Par. 6-22 to - 20.0mA]Enter the high current value corresponding to the high refer-ence/feedback value set in par. 6-25.6-24 Terminal 54 Low Ref./Feedb. ValueRange: Function:0.000Unit *[-1000000.000 to par.6-25]Enter the analog input scaling value that corresponds to the lowvoltage/low current value set in par. 6-20/6-22.6-25 Terminal 54 high ref./feedb. valueRange: Function:100.000Unit *[Par. 6-24 to1000000.000]Enter the analog input scaling value that corresponds to the highvoltage/high current value set in par. 6-21/6-23.6-26 Terminal 54 Filter Time ConstantRange: Function:0.001s* [0.001 - 10.000 s] Enter the time constant. This is a first-order digital low pass filtertime constant for suppressing electrical noise in terminal 54. Ahigh time constant value improves dampening but also increa-ses the 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 mon-itoring. E.g. to be used if the analog outputs are used as part ofa decentral I/O system (e.g. when not part of any frequencyconverter related control functions, but feeding an external con-trol system with data)[0] Disabled[1] * Enabled2.8.6. 6-3* Analog Input 3 (MCB 101)Parameter group for configuring the scale and limits for analog input 3 (X30/11) placed on optionmodule MCB 101.2.
