Danfoss VLT FC 103 Programming Guide

26-15 Term. X42/1 High Ref./Feedb. Value
Range: Function:
100 * [-999999.999 -
999999.999
]
Enter the analog input scaling
value that corresponds to the high
voltage value set in 26-11 Terminal
X42/1 High Voltage.
26-16 Term. X42/1 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 noise in terminal X42/1. 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.
26-17 Term. X42/1 Live Zero
Option: Function:
This parameter makes it possible to enable the
Live
Zero monitoring. E.g. where the analog input
is a of the frequency converter control, rather
than being used as of a decentral I/O system,
such as a Building Management System.
[0] Disabled
[1] * Enabled
3.20.3 26-2* Analog Input X42/3
26-20 Terminal X42/3 Low Voltage
Range: Function:
0.07 V* [ 0 - par.
6-31
V]
Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
26-24 Term. X42/3 Low Ref./Feedb. Value.
26-21 Terminal X42/3 High Voltage
Range: Function:
10 V* [ par. 6-30 -
10
V]
Enter the high voltage value. This analog
input scaling value should correspond to
the high reference/feedback value set in
26-25 Term. X42/3 High Ref./Feedb. Value.
26-24 Term. X42/3 Low Ref./Feedb. Value
Range: Function:
0 * [-999999.999 -
999999.999
]
Enter the analog input scaling value
that corresponds to the low voltage
value set in 26-20 Terminal X42/3 Low
Voltage.
26-25 Term. X42/3 High Ref./Feedb. Value
Range: Function:
100 * [-999999.999 -
999999.999
]
Enter the analog input scaling
value that corresponds to the high
voltage value set in 26-21 Terminal
X42/3 High Voltage.
26-26 Term. X42/3 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 noise in terminal X42/3. 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.
26-27 Term. X42/3 Live Zero
Option: Function:
This parameter makes it possible to enable the
Live
Zero monitoring. E.g. where the analog input
is a of the frequency converter control, rather
than being used as of a decentral I/O system,
such as a Building Management System.
[0] Disabled
[1] * Enabled
3.20.4 26-3* Analog Input X42/5
26-30 Terminal X42/5 Low Voltage
Range: Function:
0.07 V* [ 0 - par.
6-31
V]
Enter the low voltage value. This analog
input scaling value should correspond to
the low reference/feedback value set in
26-34 Term. X42/5 Low Ref./Feedb. Value.
26-31 Terminal X42/5 High Voltage
Range: Function:
10 V* [ par. 6-30 -
10
V]
Enter the high voltage value. This analog
input scaling value should correspond to
the high reference/feedback value set in
26-35 Term. X42/5 High Ref./Feedb. Value.
26-34 Term. X42/5 Low Ref./Feedb. Value
Range: Function:
0 * [-999999.999 -
999999.999
]
Enter the analog input scaling value
that corresponds to the low voltage
value set in 26-30 Terminal X42/5 Low
Voltage.
