The analog output signal processing
The analog output is controlled by use of "pointers". This parameter
selects the word that is the desired output. Example:
+.001.002.00 = MOTOR SPEED FILT.
Parameter index or a constant value. See
information on the difference.
Defines the minimum value of the analog output signal AO1.
Zero mA.
Four mA.
Ten mA. 50% offset on 0 to 20 mA for testing or indication of direction. 3
Defines the filtering time constant for analog output AO1.

Filtered Signal
T
Note: Even if you select 0 s as the minimum value, the signal is still
filtered with a time constant of 10 ms due to the signal interface
hardware. This cannot be changed by any parameters.
Filter time constant
When the value of the signal selected in
equals this parameter, the output = 20 mA.
