Danfoss VLT AHF 005 Programming Guide

6-23 Terminal 54 High Current
Range: Function:
20 mA* [ par. 6-22 -
20 mA]
Enter the high current value
corresponding to the high reference/
feedback value set in
parameter 6-25 Terminal 54 High Ref./Feedb.
Value.
6-24 Terminal 54 Low Ref./Feedb. Value
Range: Function:
0* [-999999.999 -
999999.999 ]
Enter the analog input scaling value that
corresponds to the low voltage/low
current value set in
parameter 6-20 Terminal 54 Low Voltage
and parameter 6-22 Terminal 54 Low
Current.
6-25 Terminal 54 High Ref./Feedb. Value
Range: Function:
100* [-999999.999 -
999999.999 ]
Enter the analog input scaling value
that corresponds to the high voltage/
high current value set in
parameter 6-21 Terminal 54 High Voltage
and parameter 6-23 Terminal 54 High
Current.
6-26 Terminal 54 Filter Time Constant
Range: Function:
0.001 s* [0.001 -
10 s]
NOTICE
This parameter cannot be adjusted
while the motor is running.
Enter the lter time constant. This is a
rst-order digital low-pass lter time
constant for suppressing electrical noise in
terminal 54. A high time constant value
improves dampening but also increases
the time delay through the lter.
6-27 Terminal 54 Live Zero
Option: Function:
Disables the live zero-monitoring, for example if
the analog outputs are used as part of a
decentral I/O system (that is if these are used to
feed a building management system with data,
and not as part of any control functions related
to the frequency converter).

3.8.4 6-3* Analog Input 3 MCB 101
Parameter group for conguring 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* [ 0 - par.
6-31 V]
Sets the analog input scaling value to
correspond to the low reference/feedback
value (set in parameter 6-34 Term. X30/11
Low Ref./Feedb. Value).
6-31 Terminal X30/11 High Voltage
Range: Function:
10 V* [ par. 6-30 -
10 V]
Sets the analog input scaling value to
correspond to the high reference/feedback
value (set in parameter 6-35 Term. X30/11
High Ref./Feedb. Value).
6-34 Term. X30/11 Low Ref./Feedb. Value
Range: Function:
0* [-999999.999 -
999999.999 ]
Sets the analog input scaling value to
correspond to the low voltage value (set
in parameter 6-30 Terminal X30/11 Low
Voltage).
6-35 Term. X30/11 High Ref./Feedb. Value
Range: Function:
100* [-999999.999 -
999999.999 ]
Sets the analog input scaling value to
correspond to the high voltage value
(set in parameter 6-31 Terminal X30/11
High Voltage).
6-36 Term. X30/11 Filter Time Constant
Range: Function:
0.001 s* [0.001 - 10
s]
NOTICE
This parameter cannot be adjusted
while the motor is running.
Enter the lter time constant. This
constant is a rst-order digital low-pass
lter time for suppressing electrical noise
in terminal X30/11. A high value improves
dampening, but also increases the delay
through the lter.
