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 HighLine inverter.
2. Select the
Application parameters
tab from the
Workspace
.
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: U/f definable"
(from version 04.00.00 onwards)
.
With this motor control, the V/f characteristic can be freely defined.
• "11: VFCplusEco: V/f energy-saving"
(from version 10.00.00 onwards)
.
With this motor control, the motor is always operated in an optimal efficiency range via
a cos
ϕ
control and the resulting voltage reduction (reduced copper losses in the
asynchronous motor).

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.
