26-41 Terminal X42/7 Output Min. Scale
Range:
*
0%
Function:
[Par. 26-34 - Enter the analog input scaling value that corresponds to the high
1000000.000] voltage value set in par 26-21.
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 X42/5. 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.

Set the function of terminal X42/7 as an analog current output.
