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 6-25 Terminal 54
High Ref./Feedb. Value.
6-24 Terminal 54 Low Ref./Feedb. Value
Range: Function:
-1 * [-999999.999 -
999999.999 ]
Enter the analog input scaling value
that corresponds to the low
voltage/low current value set in
6-20 Terminal 54 Low Voltage and
6-22 Terminal 54 Low Current.
6-25 Terminal 54 High Ref./Feedb. Value
Range: Function:
Size related* [-999999.999 -
999999.999
]
Enter the analog input scaling
value that corresponds to the
high voltage/high current value
set in 6-21 Terminal 54 High
Voltage and 6-23 Terminal 54
High Current.
6-26 Terminal 54 Filter Time Constant
Range: Function:
0.001 s* [0.001 - 10
s]
Enter the time constant. This is a first-
order
digital low pass filter time constant
for suppressing electrical noise in
terminal 54. A high time constant value
improves dampening but also increases
the time delay through the filter.
NOTE
This
parameter cannot be adjusted while the motor is
running.
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).

3.8.5 6-3* Analog Input 3 MCB 101
Parameter group for configuring 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 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 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 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 6-31 Terminal X30/11
High Voltage).
6-36 Term. X30/11 Filter Time Constant
Range: Function:
0.001 s* [0.001 - 10 s]
A 1
st
order digital low pass filter time
constant for suppressing electrical noise
on terminal X30/11.
NOTE
This
parameter cannot be changed while the motor is
running.
6-37 Term. X30/11 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 decentral I/O
system (e.g. when not of any frequency converter
related control functions, but feeding a Building
Management System with data).

3.8.6 6-4* Analog Input 4 MCB 101
Parameter group for configuring the scale and limits for
analog
input 4 (X30/12) placed on option module MCB
101.
