3.7.6 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: 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:
NOTICE
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.
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 LCP in
parameter 16-65 Analog Output 42 [mA].
Indicates no signal on the analog output.
NOTICE
This option is available only with
software version 48.XX.
The actual position. 0–20 mA corresponds to
parameter 3-06 Minimum Position to
parameter 3-07 Maximum Position.

The value is taken from parameter 16-37 Inv.
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
