Motor control (MCTRL)
V/f characteristic control (VFCplus)
126 L Firmware ≤ 11.00 - DMS 8.0 EN - 10/2011
5.4.1 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 from the Overview dialog level in the Motor control list
field:
• "6: VFCplus: V/f linear" for linear characteristic or
• "8: VFCplus: V/f quadr" for square-law characteristic
More available V/f characteristic control modes:
• "10:VFCplus:V/f definable" (from version 04.00.00).
The V/f characteristic can be freely defined with this motor control. Defining
a user-defined V/f characteristic ( 140)
• "11: VFCplusEco: V/f energy-saving" (from version 10.00.00).
With this motor control, the motor is always operated in an optimal efficiency
range via a cosϕ control and the resulting voltage reduction (reduced copper
losses in the asynchronous motor). V/f characteristic control - energy-saving
(VFCplusEco) ( 144)
4. Click the Motor control V/f button to change to the Overview Motor control V/f
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.
