Danfoss VLT AHF 005 Operating Instructions

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 of a de-central I/O
system (e.g. when not as of any frequency
converter related control functions, but feeding a
Building Management system with data).

6-20 Terminal 54 Low Voltage
Range: Function:
0.07 V* [ 0 - par.
6-21 V]
Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value, set in
parameter 6-24 Terminal 54 Low Ref./Feedb.
Value.
6-21 Terminal 54 High Voltage
Range: Function:
10 V* [ par. 6-20
- 10 V]
Enter the high voltage value. This analog
input scaling value should correspond 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 time constant. This is a first-
order digital low pass filter time constant
for suppressing electrical noise in terminal
6-26 Terminal 54 Filter Time Constant
Range: Function:
54. A high time constant value improves
dampening but also increases the time
delay through the filter.
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 of a de-central I/O
system (e.g. when not as of any frequency
converter related control functions, but feeding a
Building Management System with data).
