3.7.3 AN-1# Analog Input 1
Parameters for configuring the scaling and limits for analog
input 1 (terminal 53).
Illustration 3.26
AN-10 Terminal 53 Low Voltage
Range:
Function:
0.07
V
*
[0 - par.
AN-11 V]
NOTICE
For the live zero alarms to work,
parameter AN-10 Terminal 53 Low
Voltage
must have a value of 1 V or
greater.
Enter the low voltage value. This analog
input scaling value should correspond to the
low reference feedback value set in
parameter AN-14 Terminal 53 Low Ref./Feedb.
AN-11 Terminal 53 High Voltage
Range:
Function:
10 V
*
[par. AN-10
- 10 V]
Enter the high-voltage value. This analog
input scaling value should correspond to the
high reference feedback value set in
parameter AN-15 Terminal 53 High Ref./Feedb.
.
AN-12 Terminal 53 Low Current
Range:
Function:
4 mA
*
[0 - par.
AN-13
mA]
Enter the low current value. This reference
signal should correspond to the low reference
feedback value, set in
parameter AN-14 Terminal 53 Low Ref./Feedb.
. Set the value at >2 mA to activate the
parameter AN-01 Live Zero Timeout Function
AN-13 Terminal 53 High Current
Range:
Function:
20 mA
*
[par. AN-12
- 20 mA]
Enter the high current value
corresponding to the high reference/
feedback set in
AN-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
and
AN-15 Terminal 53 High Ref./Feedb. Value
Range:
Function:
100.000
*
[-999999.999 -
999999.999]
Enter the analog input scaling value
that corresponds to the high voltage/
high current value set in
parameter AN-11 Terminal 53 High
and
.
AN-16 Terminal 53 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 filter time constant. This
constant is a first-order digital low-pass
filter time for suppressing electrical noise
in terminal 53. A high value improves
dampening, but also increases the delay
through the filter.
AN-17 Terminal 53 Live Zero
Option:
Function:
Disables the live zero monitoring, for example if
the analog outputs are used as part of a
decentral I/O system (that is if these are used to
feed a building management system with data,
and not as part of any control functions related
to the frequency converter).
