6-24 Terminal 54 Low Ref./Feedb. Value
Range: Function:
0.000 N/A* [-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the low voltage/low current value set in
par. 6-20
Terminal 54 Low Voltage and par. 6-22 Terminal 54 Low Current .
6-25 Terminal 54 High Ref./Feedb. Value
Range: 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 in
par. 6-21
Terminal 54 High Voltage and par. 6-23 Terminal 54 High Current .
6-26 Terminal 54 Filter Time Constant
Range: 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 suppressing
electrical noise in terminal 54. A high time constant value improves dampening but also increases
the time delay through the filter.
This parameter cannot be adjusted while the motor is running.
6-27 Terminal 54 Live Zero
Option: Function:
This parameter makes it possible to disable the Live Zero monitoring. E.g. to be used if the analog
outputs 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).

3.8.5 6-3* Analog Input 3 MCB 101
Parameter group for configuring the scale and limits for analog input 3 (X30/11) placed on option module MCB 101.
6-30 Terminal X30/11 Low Voltage
Range: Function:
0.07 V* [Application dependant] Sets the analog input scaling value to correspond to the low reference/feedback value (set in
par. 6-34
Term. X30/11 Low Ref./Feedb. Value ).
6-31 Terminal X30/11 High Voltage
Range: Function:
10.00 V* [Application dependant] Sets the analog input scaling value to correspond to the high reference/feedback value (set in
par. 6-35
Term. X30/11 High Ref./Feedb. Value ).
6-34 Term. X30/11 Low Ref./Feedb. Value
Range: Function:
0.000 N/A* [-999999.999 - 999999.999 N/A] Sets the analog input scaling value to correspond to the low voltage value (set in par. 6-30 Terminal
X30/11 Low Voltage
).
6-35 Term. X30/11 High Ref./Feedb. Value
Range: Function:
100.000 N/
A*
[-999999.999 - 999999.999 N/A] Sets the analog input scaling value to correspond to the high voltage value (set in par. 6-31 Terminal
X30/11 High Voltage
).
