3.8.3 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 - par.
6-11
V]
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.
6-11 Terminal 53 High Voltage
Range: Function:
10 V* [ par.
6-10 -
10
V]
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.
6-12 Terminal 53 Low Current
Range: Function:
4 mA* [ 0 - par.
6-13
mA]
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.
6-13 Terminal 53 High Current
Range: Function:
20 mA* [ par. 6-12 - 20
mA]
Enter
the high current value
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 * [-999999.999 -
999999.999
]
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.
6-15 Terminal 53 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 6-11 Terminal 53 High
Voltage and 6-13 Terminal 53
High Current.
6-16 Terminal 53 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 53. 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.
6-17 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).
[0] Disabled
[1] * Enabled
3.8.4 6-2* Analog Input 2
Parameters for configuring the scaling and limits for
analog input 2 (terminal 54).
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
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
6-25 Terminal 54 High Ref./Feedb. Value.
6-22 Terminal 54 Low Current
Range: Function:
4 mA* [ 0
- par.
6-23
mA]
Enter the low current value. This reference
signal should correspond to the low
reference/feedback value, set in
6-24 Terminal 54 Low Ref./Feedb. Value. The
value must be set at >2 mA to activate the
Live Zero Time-out Function in 6-01 Live Zero
Timeout Function.
