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
5.9.1 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 HighLine inverter.
2. Select the Application parameters tab from the Workspace.
3. Go to the Overview dialog level and the Motor control list field (C00006
) to select the
"2: SC: Servo control ASM" motor control.
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.
Detailed information on the speed feedback can be found in the chapter
"Encoder/feedback system
". ( 276)
