5.5.1 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. Select the motor control "11: VFCplusEco: V/f energy-saving" from the Overview dialog box
in the Motor control list field:
4. Click the Motor control V/f Eco 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.
Stop!
• For adjustment, observe the thermal performance of the connected asynchronous
motor at low output frequencies.
• Usually, standard asynchronous motors with insulation class B can be operated for
a short time with their rated current in the frequency range 0 Hz ... 25 Hz.
• Contact the motor manufacturer to get the exact setting values for the max.
permissible motor current of self-ventilated motors in the lower speed range.
• The nameplate data of the motor (at least rated speed and rated frequency) must be
entered if, instead of a standard motor, an asynchronous motor is used with the
following values:
•rated frequency ≠ 50 Hz (star) or
•rated frequency ≠ 87 Hz (delta) or
• number of pole pairs ≠ 2
