2.2 List of parameters
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)
Description: Activates/de-activates the automatic sensing of the switch-in level for the Vdc_max controller. When the sensing
function is de-activated, the activation threshold r1282 for the Vdc_max controller is determined from the
parameterized connection voltage p0210.
Value: 0: Automatic detection inhibited
1: Automatic detection enabled
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
