6-14 Terminal 53 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 set in
par. 6-10
Terminal 53 Low Voltage and par. 6-12 Terminal 53 Low Current .
6-15 Terminal 53 High Ref./Feedb. Value
Range: Function:
Application
dependent*
[-999999.999 - 999999.999 N/A] Enter the analog input scaling value that corresponds to the high voltage/high current value set in
par. 6-11
Terminal 53 High Voltage and par. 6-13 Terminal 53 High Current .
6-16 Terminal 53 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 53. 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.
6-17 Terminal 53 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).

3.8.4 6-2* Analog Input 2
Parameters for configuring the scaling and limits for analog input 2 (terminal 54).
6-20 Terminal 54 Low Voltage
Range: Function:
0.07 V* [Application dependant] Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value, set in par. 6-24
Terminal 54 Low Ref./Feedb. Value .
6-21 Terminal 54 High Voltage
Range: Function:
10.00 V* [Application dependant] Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par. 6-25
Terminal 54 High Ref./Feedb. Value .
6-22 Terminal 54 Low Current
Range: Function:
4.00 mA* [Application dependant] Enter the low current value. This reference signal should correspond to the low reference/feedback
value, set in par. 6-24
Terminal 54 Low Ref./Feedb. Value . The value must be set at >2 mA in order
to activate the Live Zero Time-out Function in par. 6-01
Live Zero Timeout Function .
6-23 Terminal 54 High Current
Range: Function:
20.00 mA* [Application dependant] Enter the high current value corresponding to the high reference/feedback value set in
par. 6-25
Terminal 54 High Ref./Feedb. Value .
