Parameter Description
3.8.2 6-1* Analog Input 1
Parameters for configuring the scaling and limits for
analog input 1 (terminal 53).
6-10 Terminal 53 Low Voltage
Range: Function:
0.07 V [ 0.00 - par. Enter the low voltage value. This analog
*
6-11 V] input scaling value should correspond
to the low reference/feedback value set
in 6-14 Terminal 53 Low Ref./Feedb. Value.
6-11 Terminal 53 High Voltage
Range: Function:
10.00 V [ par. 6-10 - Enter the high voltage value. This
*
10.00 V] analog input scaling value should
correspond to the high reference/
feedback value set in 6-15 Terminal 53
High Ref./Feedb. Value.
6-12 Terminal 53 Low Current
Range: Function:
4.00 [ 0.00 - Enter the low current value. This reference
mA par. 6-13 signal should correspond to the low
*
mA] 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 Timeout Function in
6-01 Live Zero Timeout Function.
6-13 Terminal 53 High Current
Range: Function:
20.00 mA [ par. 6-12 - Enter the high current value
*
20.00 mA] corresponding to the high
reference/feedback set in
6-15 Terminal 53 High Ref./Feedb.
Value.
6-14 Terminal 53 Low Ref./Feedb. Value
Range: Function:
0.000 [-999999.999 - Enter the analog input scaling
*
999999.999 ] value that corresponds to the low
voltage/low current set in
6-10 Terminal 53 Low Voltage and
6-12 Terminal 53 Low Current.
6-15 Terminal 53 High Ref./Feedb. Value
Range:
Size related [-999999.999 - 999999.999 ]

6-16 Terminal 53 Filter Time Constant
Range:
0.001 s
NOTE!
This parameter cannot be adjusted while the motor is
running.
6-17 Terminal 53 Live Zero
Option:
[0]
[1]
Function:
MG11CD22 - VLT ® is a registered Danfoss trademark
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.
Function:
This parameter makes it possible to disable the
Live Zero monitoring. For example, this is to be
used if the analog outputs are used as part of a
de-central I/O system (e.g., when not used as part
of any adjustable frequency drive related control
functions, but for feeding a building management
system with data).
