ABB ACS850-04 - Analogue Inputs

Parameters 119
Min Combination of selections Speed and Torque: Torque selector
compares the torque reference and the speed controller
output and the smaller of the two is used.
3
Max Combination of selections Speed and Torque: Torque selector
compares the torque reference and the speed controller
output and the greater of the two is used.
4
Add Combination of selections Speed and Torque: Torque selector
adds the speed controller output to the torque reference.

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
