2.2 List of parameters
Description: Sets the scaling of the precontrol characteristic for the start of field weakening.
For values above 100 % and for partial load situations, the field weakening starts at higher speeds.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: If the start of field weakening is shifted to lower speeds, then the voltage reserve is increased for partial load
situations.
If the start of field weakening is shifted to higher speeds, the voltage reserve is appropriately reduced so that for fast
load changes, it can be expected that this will have a negative impact on the dynamic performance.
Description: Sets the proportional gain for the flux controller.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Note: The value is automatically pre-assigned dependent on the motor when the drive system is first commissioned.
When calculating controller parameters (p0340 = 4), this value is re-calculated.
Description: Sets the integral time for the flux controller.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: The value is automatically pre-assigned dependent on the motor when the drive system is first commissioned.
When calculating controller parameters (p0340 = 4), this value is re-calculated.
Description: Display and connector output for the output of the field weakening controller (synchronous motor).
Index: [0] = PI output
[1] = I output
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
