Actual signals and parameters
218
AI2 Uses analog input 2 for ACT2 2
CURRENT Uses current for ACT1 3
TORQUE Uses torque for ACT1 4
POWER Uses power for ACT1 5
COMM ACT 1 Uses value of signal 0158 PID COMM VALUE 1 for ACT1 6
COMM ACT 2 Uses value of signal 0159 PID COMM VALUE 2 for ACT1 7
FREQ INPUT Frequency input 8
4017 ACT2 INPUT Defines the source for actual value ACT2. See also parameter 4020 ACT2
MINIMUM.
AI2
See parameter 4016 ACT1 INPUT.
4018 ACT1 MINIMUM Sets the minimum value for ACT1.
Scales the source signal used as the actual value ACT1 (defined by
parameter
4016 ACT1 INPUT). For parameter values 6 (COMM ACT 1) and
7 (COMM ACT 2) scaling is not done.
The ACT minimum and maximum correspond the 1301 MINIMUM AI1 and
1302 MAXIMUM AI1 settings as follows.
A= Normal; B = Inversion (ACT1 minimum > ACT1 maximum)
0
-1000…1000% Value in percent 1 = 1%
4019 ACT1 MAXIMUM Defines the maximum value for the variable ACT1 if an analog input is
selected as a source for ACT1. See parameter
4016 ACT1 INPUT. The
minimum ( 4018 ACT1 MINIMUM) and maximum settings of ACT1 define how
the voltage/current signal received from the measuring device is converted to
a percentage value used by the process PID controller.
See parameter
4018 ACT1 MINIMUM.
