2.2 List of parameters
Description: Enters the dynamic torque setpoint for the low-speed range for sensorless vector control.
This parameter is entered as a percentage referred to the rated motor torque (r0333).
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: When accelerating and braking p1611 is added to p1610 and the resulting total torque is converted into an
appropriate current setpoint and controlled.
For pure accelerating torques, it is always favorable to use the torque pre-control of the speed controller (p1496).
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:
