Config.SetpointUpperLimit REAL +3.40282
2e+38
High limit of setpoint
If you set SetpointUpperLimit outside the process value limits, the
configured absolute process value high limit is preassigned as the
setpoint high limit.
If you configure SetpointUpperLimit within the process value limits,
this value is used as the setpoint high limit.
Config.SetpointLowerLimit REAL -
3.402822
e+38
Low limit of the setpoint
If you set SetpointLowerLimit outside the process value limits, the
configured absolute process value low limit is preassigned as the
setpoint low limit.
If you set SetpointLowerLimit within the process value limits, this
value is used as the setpoint low limit.
Config.MinimumOnTime REAL 0.0 Minimum ON time
Minimum time in seconds for which the servo drive must be
switched on.
Config.MinimumOnTime is only effective if Output_UP and Out-
put_DN are used (Config.OutputPerOn = FALSE).
Config.MinimumOffTime REAL 0.0 Minimum OFF time
Minimum time in seconds for which the servo drive must be
switched off.
Config.MinimumOffTime is only effective if Output_UP and Out-
put_DN are used (Config.OutputPerOn = FALSE).
Config.TransitTime REAL 30.0 Motor transition time
Time in seconds the actuating drive requires to move the valve
from the closed to the opened state.
Config.InputScaling.Upper-
PointIn
REAL 27648.0 Scaling Input_PER high
Input_PER is converted to a percentage based on the two value
pairs UpperPointOut, UpperPointIn and LowerPointOut, Lower-
PointIn of the InputScaling structure.
Config.InputScaling.Lower-
PointIn
REAL 0.0 Scaling Input_PER low
Input_PER is converted to a percentage based on the two value
pairs UpperPointOut, UpperPointIn and LowerPointOut, Lower-
PointIn of the InputScaling structure.
Config.InputScaling.Upper-
PointOut
REAL 100.0 Scaled high process value
Input_PER is converted to a percentage based on the two value
pairs UpperPointOut, UpperPointIn and LowerPointOut, Lower-
PointIn of the InputScaling structure.
Config.InputScaling.Lower-
PointOut
REAL 0.0 Scaled low process value
Input_PER is converted to a percentage based on the two value
pairs UpperPointOut, UpperPointIn and LowerPointOut, Lower-
PointIn of the InputScaling structure.
Config.FeedbackScaling
.UpperPointIn
REAL 27648.0 Scaling Feedback_PER high
Feedback_PER is converted to a percentage based on the two
value pairs UpperPointOut, UpperPointIn and LowerPointOut,
LowerPointIn of the FeedbackScaling structure.
