8400 StateLine C | Reference manual
Motor control (MCTRL)
Sensorless control for synchronous motors (SLPSM)
176 L Firmware ≤ 11.00 - DMS 8.0 EN - 10/2011
The sensorless control for synchronous motors has similar advantages for the closed-loop
controlled operating range and the servo control (SC) for synchronous motors. Compared
to asynchronous motors, there are the following advantages:
Higher power density of the motor
Higher efficiency
Limitation of the maximum torque in motor mode and generator mode in closed-loop
operating range
Implementation of simple positioning
5.8.1 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. Go to Workspace and change to the Application parameters tab.
3. Select the motor control "3: SLPSM: Sensorless PSM" from the Overview dialog level
in the Motor control list field:
4. Click the Motor control servo SLPSM 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.
