Function:
Terminal X42/5 can be programmed as an analog input accepting a voltage or input from either Pt
1000 (1000 at 0 C) or Ni 1000 (1000
Pt 1000, [2] and Ni 1000, [4] if operating in Celsius - Pt 1000, [3] and Ni 1000, [5] if operating in
Fahrenheit.
Notice: If the input is not in use, it must be set for Voltage!
If set for temperature and used as feed back, the unit must be set for either Celsius or Fahrenheit

Function:
Enter the analog input scaling value that corresponds to the low voltage value set in

Function:
Enter the analog input scaling value that corresponds to the high voltage value set in
Terminal X42/1 High Voltage
par. 26-11
Function:
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. This parameter cannot be adjusted while the motor is running.
Function:
This parameter makes it possible to enable the Live Zero monitoring. E.g. where the analog input
is a part of the frequency converter control, rather than being used as part of a decentral I/O system,
such as a Building Management System.
