Parameter 6-26 Terminal 54 Filter Time Constant
Table 358: Parameter 6-26 Terminal 54 Filter Time Constant
6-26 Terminal 54 Filter Time Constant
Default value: 0.001 s
Conversion index: -3
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.
Parameter 6-50 Terminal 42 Output

6-50 Terminal 42 Output
Default value: [0] No operation
Conversion index: –
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].

Description
Indicates no signal on the analog output.
0 Hz = 0 mA; 100 Hz = 20 mA.
Parameter 3-00 Reference Range [Min - Max] 0% = 0 mA; 100% = 20 mA
Parameter 3-00 Reference Range [-Max - Max] -100% = 0 mA; 0% = 10 mA; +100% = 20 mA.
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.
20 mA × 22 A
= 11 . 46 mA
38 . 4 A
When the normal motor current is equal to 20 mA, the output setting of parameter 6-52 Terminal 42
