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.

Function:
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
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] .
When no signal on the analog output.
0 Hz = 0 mA; 100 Hz = 20 mA.
Par. 3-00 Reference Range [Min - Max] 0% = 0 mA; 100% = 20 mA
Reference Range
Par. 3-00 [-Max - Max] -100% = 0 mA; 0% = 10 mA; +100% = 20 mA
Inv. Max. Current
Value is taken from par. 16-37
20 mA.
Example: Inverter norm current (11 kW) = 24 A. 160 % = 38.4 A. Motor norm current = 22 A Read-
out 11.46 mA.
mA x A

= 11.46 mA
38.4 A
In case the norm motor current is equal to 20 mA, the output setting of par. 6-52
Max Scale is:

Norm
The torque setting is related to setting in par. 4-16
The torque is related to the motor torque setting.
Taken from par. 1-20 Motor Power [kW]
Maximum Reference
Taken from par. 3-03
Torque reference related to 160% torque.
In relation to par. 4-19 Max Output Frequency
0 Hz = 4 mA, 100 Hz = 20 mA
Par. 3-00 Reference Range [Min-Max] 0% = 4 mA; 100% = 20 mA
Par. 3-00 Reference Range [-Max-Max] -100% = 4mA; 0% = 12 mA; +100% = 20 mA
