In comparison to the V/f characteristic control without feedback, the following can be achieved by
means of sensorless vector control SLVC:
• A higher maximum torque throughout the entire speed range
• A higher speed accuracy
• A higher concentricity factor
• A higher level of efficiency
• The implementation of torque-controlled operation with speed limitation
• The limitation of the maximum torque in motor and generator mode for speed-controlled
operation
5.7.1 Parameterisation dialog/signal flow

Proceed as follows to open the dialog for parameterising the motor control:
1. »Engineer« Go to the Project view and select the 8400 StateLine controller.
2. Select the Application parameters tab from the Workspace.
3. Select the motor control "4: SLVC: Vector control" from the Overview dialog level in the
Motor control list field ( C00006 ):
4. Click the Motor control vector button to change to the Overview  Motor control vector
dialog box.
• This dialog level only shows a simplified signal flow with the most important
parameters.
• When you click the >>More details button in the left-most position, a signal flow with
more details/parameters is displayed, as shown in the following subchapter.
