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 [
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:

26-16 Term. X42/1 Filter Time Constant
Range: Function:
NOTICE
0.005 s [0.005 - 10 s]
*
This parameter cannot be
adjusted while the motor is
running.
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.
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.
