Parameter Descriptions
AN-44 Term. X30/12 Low Ref./Feedb. Value
Range: Function:
0 [-999999.999 - Sets the analog output scaling value to
*
999999.999] correspond to the low voltage value set
in parameter AN-40 Terminal X30/12 Low
Voltage.
AN-45 Term. X30/12 High Ref./Feedb. Value
Range: Function:
100 [-999999.999 - Sets the analog input scaling value to
*
999999.999] correspond to the high-voltage value
set in parameter AN-41 Terminal X30/12
High Voltage.
AN-46 Term. X30/12 Filter Time Constant
Range: Function:
NOTICE
0.001 s [0.001 - 10
*
s]
This parameter cannot be adjusted
while the motor is running.
Enter the filter time constant. This
constant is a first-order digital low-pass
filter time for suppressing electrical noise
in terminal X30/12. A high value improves
dampening, but also increases the delay
through the filter.
AN-47 Term. X30/12 Live Zero
Option: Function:
This parameter makes it possible to disable the
live zero monitoring. For example, this is used if
the analog outputs are used as part of a
decentral I/O system (for example when not part
of any control functions related to the frequency
converter, but feeding an external control system
with data).

3.8.6 AN-5# Analog Output 42
Parameters to configure the scaling and limits for Analog
Output 1 (terminal 42)
AN-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 the keypad in
parameter DR-65 Analog Output 42 [mA].
[0] No Indicates no signal on the analog output.

The value is taken from
parameter DR-37 Drive Max. Current. The
inverter maximum current (160% current) 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 x 22 A
= 11 . 46 mA

In case the normal motor current is equal to
20 mA, the output setting of
