Pset_ControllerTypeProportional |
Definition from IAI: Properties for signal handling for an proportional controller taking setpoint and feedback inputs and creating a single valued output. HISTORY: In IFC 2x4, SignalFactor1, SignalFactor2 and SignalFactor3 changed to ProportionalConstant, IntegralConstant and DerivativeConstant. SignalTime1 and SignalTime2 changed to SignalTimeIncrease and SignalTimeDecrease. |

Property Description and Allowed Values |
Property Value |
ControlType |
The type of signal modification.
PROPORTIONAL: Output is proportional to the control error. The gain of a proportional control (Kp) will have the effect of reducing the rise time and reducing , but never eliminating, the steady-state error of the variable controlled.
PROPORTIONALINTEGRAL: Part of the output is proportional to the control error and part is proportional to the time integral of the control error. Adding the gain of an integral control (Ki) will have the effect of eliminating the steady-state error of the variable controlled, but it may make the transient response worse.
PROPORTIONALINTEGRALDERIVATIVE: Part of the output is proportional to the control error, part is proportional to the time integral of the control error and part is proportional to the time derivative of the control error. Adding the gain of a derivative control (Kd) will have the effect of increasing the stability of the system, reducing the overshoot, and improving the transient response of the variable controlled. |

PhaseAngle |
The angular difference between two waveforms of the same frequency. |
|
0. |
PhaseReference |
The phase identification used for the device electrical input. This should be the same phase identifier that is used for the conductor segment providing the electrical service to the device. In general, it is recommended that IEC recommendations for phase identification are used (L1, L2 etc.). However, other phase identifiers may be used such as by color (Red, Blue, Yellow) or by number (1, 2, 3) etc. |

NumberOfPoles |
The number of live lines that is intemnded to be handled by the device. |

HasProtectiveEarth |
Indicates whether the electrical device has a protective earth connection (=TRUE) or not (= FALSE). |
|
false |
IP_Code |
IEC 60529 (1989) Classification of degrees of protection provided by enclosures (IP Code). |
|
n/a |
InsulationStandardClass |
Insulation standard classes provides basic protection information against electric shock. Defines levels of insulation required in terms of constructional requirements (creepage and clearance distances) and electrical requirements (compliance with electric strength tests). Basic insulation is considered to be shorted under single fault conditions. The actual values required depend on the working voltage to which the insulation is subjected, as well as other factors. Also indicates whether the electrical device has a protective earth connection. |
