Function:
Enter the low voltage value. This analog
input scaling value should correspond
to the low reference/feedback value set
in 6-14 Terminal 53 Low Ref./Feedb. Value.
Function:
Enter the high voltage value. This
analog input scaling value should
correspond to the high reference/
feedback value set in 6-15 Terminal 53
High Ref./Feedb. Value.
Function:
0.00 - Enter the low current value. This reference
signal should correspond to the low
reference/feedback value, set in
6-14 Terminal 53 Low Ref./Feedb. Value. The
value must be set at >2 mA in order to
activate the Live Zero Time-out Function
in 6-01 Live Zero Timeout Function.
Function:
par. 6-12 - Enter the high current value
corresponding to the high
reference/feedback set in
6-15 Terminal 53 High Ref./Feedb.
Value.
Function:
Enter the analog input scaling
value that corresponds to the low
voltage/low current set in
6-10 Terminal 53 Low Voltage and
6-12 Terminal 53 Low Current.
Function:
[-999999.999 - Enter the analog input scaling
value that corresponds to the
high voltage/high current value
set in 6-11 Terminal 53 High
Voltage and 6-13 Terminal 53
High Current.

Function:
[0.001 - Enter the time constant. This is a first-
10.000 s] 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.
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 converter related control functions, but
feeding a Building Management system with
data).
Function:
[ 0.00 - par. Enter the low voltage value. This analog
6-21 V] input scaling value should correspond
to the low reference/feedback value, set
in 6-24 Terminal 54 Low Ref./Feedb. Value.
Function:
[ par. 6-20 - Enter the high voltage value. This
10.00 V] analog input scaling value should
correspond to the high reference/
feedback value set in 6-25 Terminal 54
High Ref./Feedb. Value.
Function:
[ 0.00 - Enter the low current value. This reference
par. 6-23 signal should correspond to the low
mA] reference/feedback value, set in
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 6-01 Live Zero Timeout Function.
