Description: Displays the actual maximum possible electromotive force (EMF) of the separately excited synchronous motor.
Dependency: The value is the basis for the flux setpoint.
The maximum possible EMF depends on the following factors:
- Actual DC link voltage (r0070).
- Maximum modulation depth (p1803).
- Field-generating and torque-generating current setpoint.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Description: Sets the smoothing time for the current setpoint.
The current setpoint is generated from p1610 and p1611.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: This parameter is only effective in the range where current is injected for sensorless vector control.
Description: Displays the steady-state field generating current setpoint (Id_set).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: For index 1:
Reserved.
Description: Displays the limited field-generating current setpoint (Id_set).
This value comprises the steady-state field-generating current setpoint r1623 and a dynamic component that is only
set when changes are made to the flux setpoint.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
