Parameters 135
12.26 AI2 filter time Defines the filter time constant for analog input AI2. See
parameter 12.16 AI1 filter time.
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.
0.100 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.
4.000 mA or
0.000 V
0.000…22.000 mA
or 0.000…11.000 V
Minimum value of AI2. 1000 = 1 mA
or V
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.
20.000 mA
or 10.000 V
0.000…22.000 mA
or 0.000…11.000 V
Maximum value of AI2. 1000 = 1 mA
or V
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 maximum
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 AI1 scaling (12.28
AI2 max - 12.27 AI2 min).
-
0.00… 100.00 AI2 value 100 = 1%
