SINAMICS DCP
294 List Manual (LH21), 05/2016
Description: Sets the integrating time for the differential current controller
Description: Sets the limiting for the differential current controller.
Description: Sets the operating mode for the closed-loop control.
Value: 0: Closed-loop controlled operation
1: Directly controlled PWM
Note: Setting p55270 = 1 is only for internal Siemens testing.
Description: Sets the positive limiting for the control angle.
In conjunction with p55306, it is possible to restrict the operating range of the SINAMICS DCP.
Dependency: Refer to: p55306
Note: Examples:
Control angle limited to:
0 ... +200 %: only positive current possible
-200 ... 0 %: only negative current possible
-100 ... +100 %: only step-down possible
Description: Sets the negative limiting for the control angle.
In conjunction with p55305, it is possible to restrict the operating range of the SINAMICS DCP.
Dependency: Refer to: p55305
Note: Examples:
Control angle limited to:
0 ... +200 %: only positive current possible
-200 ... 0 %: only negative current possible
-100 ... +100 %: only step-down possible
