Motor control (MCTRL)
V/f characteristic control - energy-saving (VFCplusEco)
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 StateLine controller.
2. Go to Workspace and change to the Application parameters tab.
3. Select the motor control"11: VFCplusEco: V/f energy-saving" from the Overview
dialog box in the Motor control 11list 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
