Analog Output - Danfoss VLT FC 102 Programming Manual

Programming Guide | VLT® HVAC Drive FC 102
6-46 X30/12 Filter Time Constant
Default value: 0.005 s
Setup: All setups
Data type: Uint16
This parameter cannot be adjusted while the motor is running.
Enter the filter time constant. This is a first-order digital low-pass filter time constant for suppressing electrical noise in terminal X30/12.
Increasing the value improves dampening but also increases the time delay through the filter.
6-47 Terminal X30/12 Live Zero
Default value: [1] Enabled
Setup: All setups
Data type: Uint8
Disables the live zero monitoring, for example, if the analog outputs are used as part of a decentral I/O system (when an analog output
does not fulfil any control function, but feeds a data storage device).
Option Name
[0] Disabled
[1]* Enabled

6-5* Analog Output 1

6.8.6
Parameters for configuring the scaling and limits for analog output 1 (terminal 43). Analog outputs are current outputs of 0/4–20 mA.
Common terminal (terminal 39) is the same terminal and has the same electrical potential for analog common and digital common
connection. The resolution on the analog output is 12 bit.
6-50 Terminal 42 Output
Default value: Size related
Setup: All setups
Data type: Uint8
Values for setting the minimum reference are found in open loop parameter 3-02 Minimum Reference and in closed loop
parameter 20-13 Minimumm Reference/Feedb. Values for maximum reference for open loop are in parameter 3-03 Maximum
Reference and for closed loop parameter 20-12 Maximum Reference/Feedb.
Select the function of terminal 42 as an analog current output. Depending on the selection, the output is either a 0–20 mA or 4–20 mA
output. The current value can be read out in the LCP in parameter 16-65 Analog Output 42 [mA].
