ABB ACS850 - Analogue Inputs

Parameters 135
13
13 Analogue inputs
Analog input signal processing.
13.01 AI1 filt time Defines the filter time constant for analogue input AI1.
Note: The signal is also filtered due to the signal interface
hardware (approximately 0.25 ms time constant). This cannot
be changed by any parameter.
0.000 … 30.000 s Filter time constant. 1000 = 1 s
13.02 AI1 max Defines the maximum value for analogue input AI1. The input
type is selected with jumper J1 on the JCU Control Unit.
-22.000 … 22.000
mA or
-11.000 … 11.000 V
Maximum AI1 value. 1000 = 1 unit
13.03 AI1 min Defines the minimum value for analogue input AI1. The input
type is selected with jumper J1 on the JCU Control Unit.
-22.000 … 22.000
mA or
-11.000 … 11.000 V
