15 ANALOG OUTPUTS
The analog output signal processing
15.01 AO1 POINTER 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.
-255.255.31…+255.255.31
/ C.-32768…C.32767
Parameter index or a constant value. See 10.05 EXT1 STRT PTR for
information on the difference.

15.03 MINIMUM AO1 Defines the minimum value of the analog output signal AO1.
0 mA Zero mA. 1
4 mA Four mA. 2
10 mA Ten mA. 50% offset on 0 to 20 mA for testing or indication of direction. 3
15.04 FILTER AO1 ms Defines the filtering time constant for analog output AO1.
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.
0 …10000 ms Filter time constant 1 = 1 ms
15.05 NOM VALUE AO1 When the value of the signal selected in 15.01 AO1 POINTER 1
equals this parameter, the output = 20 mA.
