Actual signals and parameters 277
4012 SETPOINT
MIN
Defines the minimum value for the selected PID reference
signal source. See parameter
0.0%
-500.0…500.0% Value as a percentage.
Example:
Analog input AI1 is selected as the PID reference
). The reference
minimum and maximum correspond to the
and
settings as follows:
1 = 0.1%
4013 SETPOINT
MAX
Defines the maximum value for the selected PID reference
signal source. See parameters
