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

C) temperature sensors. Select the desired mode.
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

26-10 Terminal X42/1 Low Voltage
Range:
Function:
0.07 V*
[Application dependant]
Enter the low voltage value. This analog input scaling value should correspond to the low reference/
feedback value set in par. 26-14
Term. X42/1 Low Ref./Feedb. Value
.
26-11 Terminal X42/1 High Voltage
Range:
Function:
10.00 V*
[Application dependant]
Enter the high voltage value. This analog input scaling value should correspond to the high refer-
ence/feedback value set in par. 26-15
Term. X42/1 High Ref./Feedb. Value
.
26-14 Term. X42/1 Low Ref./Feedb. Value
Range:
Function:
0.000*
[-999999.999 - 999999.999 ]
Enter the analog input scaling value that corresponds to the low voltage value set in
par. 26-10
Terminal X42/1 Low Voltage
.
26-15 Term. X42/1 High Ref./Feedb. Value
Range:
Function:
100.000*
[-999999.999 - 999999.999 ]
Enter the analog input scaling value that corresponds to the high voltage value set in
par. 26-11
Terminal X42/1 High Voltage
.
26-16 Term. X42/1 Filter Time Constant
Range:
Function:
0.001 s*
[0.001 - 10.000 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. 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 part of the frequency converter control, rather than being used as part of a decentral I/O system,
such as a Building Management System.
