26-25 Terminal X42/3 High Ref./feedb. Value
Range: Function:
100.000
Unit
*
[Par. 26-24 -
1000000.000]
Enter the analog input scaling value that corresponds to the high
voltage value set in par 26-21.
26-26 Terminal X42/3 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 X42/3. 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.
26-27 Terminal X42/3 Live Zero
Option: Function:
[0] Disabled
[1] Enabled This parameter makes it possible to enable the Live Zero mon-
itoring. 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.
26-30 Terminal X42/5 Low Voltage
Range: Function:
0.07 V
*
[0.00 - par. 26-31] Enter the low voltage value. This analog input scaling value
should correspond to the low reference/feedback value set in
par 26-34.
26-31 Terminal X42/5 High Voltage
Range: Function:
10.0 V
*
[Par. 26-30 - 10.0 V] Enter the high voltage value. This analog input scaling value
should correspond to the high reference/feedback value set in
par 26-35.
26-34 Terminal X42/5 Low Ref./feedb. Value
Range: Function:
0.000
Unit
*
[-100000.000 - Par.
26-35]
Enter the analog input scaling value that corresponds to the low
voltage value set in par 26-30.
