6-46 Term. X30/12 Filter Time Constant
Range: Function:
0.001 s* [0.001 - 10.000 s]
A 1
st
order digital low pass filter time constant for suppressing electrical noise on terminal X30/12.
Par. 6-46
Term. X30/12 Filter Time Constant cannot be changed while the motor is running.
3.8.7 6-5* Analog Output 1
Parameters for configuring the scaling and limits for analog output 1, i.e. Terminal 42. Analog outputs are current outputs: 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. Resolution on analog output
is 12 bit.
6-50 Terminal 42 Output
Option: Function:
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 LCP in
par. 16-65
Analog Output 42 [mA] .
[0] * No operation When no signal on the analog output.

[103] Motor current Value is taken from par. 16-37
Inv. Max. Current . Inverter max. current (160% current) is equal to
20 mA.
Example: Inverter norm current (11 kW) = 24 A. 160 % = 38.4 A. Motor norm current = 22 A Read-
out 11.46 mA.
