Generally, the servo control offers the same advantages as the sensorless vector control (SLVC), i.e.

compared to the V/f characteristic control, the servo control (SC) can be used to achieve

• 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

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 TopLine controller.
2. Select the Application parameters tab from the Workspace.
3. Select the motor control from the Overview dialog level in the Motor control (

C00006

) list

field:

• "1: SC: Servo control PSM" for synchronous motor

- or -

• "2: SC: Servo control ASM" for asynchronous motor

4. Click the Motor control servo 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.
