26-02 Terminal X42/5 Mode
Option: Function:
Terminal X42/5 can be programmed
as an analog input accepting a
voltage or input from either Pt
1000 (1000 Ω at 0 °C) or Ni 1000
(1000 Ω at 0 °C) temperature
sensors. Select the mode.
[2] Pt 1000 [
° C] and [4] Ni 1000 [ ° C]
if operating in Celsius, or [3] Pt 1000
[
° F] and [5] Ni 1000 [ ° F] if operating
in Fahrenheit.
NOTICE
If the input is not in use, set it
for voltage.
If set for temperature and used as
feedback, set the unit for either
Celsius or Fahrenheit:

3.24.2 26-1* Analog Input X42/1
Parameters for conguring the scaling and limits for analog
input, terminal X42/1.
26-10 Terminal X42/1 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
parameter 26-14 Term. X42/1 Low
Ref./Feedb. Value.
26-11 Terminal X42/1 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
26-11 Terminal X42/1 High Voltage
Range: Function:
parameter 26-15 Term. X42/1 High
Ref./Feedb. Value.
26-14 Term. X42/1 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
parameter 26-10 Terminal X42/1 Low
Voltage.
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
parameter 26-11 Terminal X42/1 High
Voltage.
26-16 Term. X42/1 Filter Time Constant
Range: Function:
0.005 s* [0.005 - 10 s]
NOTICE
This parameter cannot be
adjusted while the motor is
running.
This is a rst-order digital low-pass
lter time constant for suppressing
noise in terminal X42/1. A high
time constant value improves
dampening, but also increases the
time delay through the lter.
26-17 Term. X42/1 Live Zero
Option: Function:
This parameter makes it possible to
enable the live zero monitoring, for
example, where the analog input is
the frequency converter control,
rather than being used as a
decentral I/O system, such as a
building management system.
