Unit
Function:
[Par. 26-14 - Enter the analog input scaling value that corresponds to the high
1000000.000] voltage value set in par 26-11.
Function:
* [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.
Function:
Disabled
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.
Function:
* [0.00 - par. 26-21] Enter the low voltage value. This analog input scaling value
should correspond to the low reference/feedback value set in
par 26-24.
Function:
* [Par. 26-20 - 10.0 V] Enter the high voltage value. This analog input scaling value
should correspond to the high reference/feedback value set in
par 26-25.
Function:
[-100000.000 - par. Enter the analog input scaling value that corresponds to the low
26-25] voltage value set in par 26-20.
