ABB ACQ580, Firmware Manual

Page: 131 / 422

Parameters 127
12.25 AI2 unit selection Selects the unit for readings and settings related to analog
input AI2. mA
V Volts. 2
mA Milliamperes. 10
12.26 AI2 filter time Defines the filter time constant for analog input AI2. See
parameter
12.16 AI1 filter time .
0.100 s
0.000…30.000 s Filter time constant. 1000 = 1 s
12.27 AI2 min Defines the minimum site value for analog input AI2.
Set the value actually sent to the drive when the analog signal
from plant is wound to its minimum setting.
0.000…20.000 mA
or 0.000…10.000 V Minimum value of AI2. 1000 = 1 unit
12.28 AI2 max Defines the maximum site value for analog input AI2.
Set the value actually sent to the drive when the analog signal
from plant is wound to its maximum setting.
0.000…20.000 mA
or 0.000…10.000 V Maximum value of AI2. 1000 = 1 unit
12.29 AI2 scaled at AI2
min Defines the real value that corresponds to the minimum
analog input AI2 value defined by parameter
12.27 AI2 min .
(Changing the polarity settings of 12.29 and 12.101 can
effectively invert the analog input.)
0.000
-32768.000…
32767.000 Real value corresponding to minimum AI2 value. 1 = 1
12.30 AI2 scaled at AI2
max Defines the real value that corresponds to the minimum
analog input AI2 value defined by parameter
12.28 AI2 max .
See the drawing at parameter of 12.29 AI2 scaled at AI2 min .
50.000
-32768.000…
32767.000 Real value corresponding to maximum AI2 value. 1 = 1
12.101 AI1 percent value Value of analog input AI1 in percent of AI1 scaling ( 12.18 AI1
max - 12.17 AI1 min ).
-
0.00…100.00% AI1 value 100 = 1%
12.102 AI2 percent value Value of analog input AI2 in percent of AI2 scaling ( 12.28 AI2
max - 12.27 AI2 min ).
-
0.00…100.00% AI2 value 100 = 1%
