2.2 List of parameters
Description:
Sets the feedback factor for the ramp-function generator.
Its ramp times are decelerated relative to the output signal of the Vdc_max controller.
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note:
For values p1288 = 0.0 to 0.5, the controller dynamics are automatically adapted internally.
Description:
Sets the proportional gain for the Vdc controller (DC link voltage controller).
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Note:
The gain factor is proportional to the capacitance of the DC link.
The parameter is pre-set to a value that is optimally adapted to the capacitance of the power unit.
Description:
Sets the integral time for the Vdc controller (DC link voltage controller).
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Description:
Sets the rate time constant for the Vdc controller (DC link voltage controller).
Dependency:
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Description:
Sets the output limit for the Vdc min controller (DC link undervoltage controller).
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
