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 54.
Increasing the value improves dampening but also increases the time delay through the filter.
4.7.4 6-5* Analog Output 1
Parameters for configuring the scaling and limits for analog output 1, that is terminal 42. 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 analog output is 12 bit.

Change during operation: True
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]
.

Motor current
The value is taken from
parameter 16-37 Inv. Max. Current
. The inverter maximum current (160% cur-
rent) is equal to 20 mA.
Example:
Inverter normal current (11 kW) is 24 A. 160 %=38.4 A. Motor normal current is 22 A, the
readout is 11.46 mA.
