Selecting the control mode
The 8400 motec controller supports various modes for motor control (open loop or closed
loop).
V/f characteristic control (VFCplus) with linear characteristic is preset.
The control mode can be selected in the »Engineer« on the
Application parameter
tab
via the
Motor control
(
) list field:
A click on the
Motor control...
button leads you to the parameterisation dialog of the
selected motor control. (The button is labelled according to the selected motor control.)
Tip!
In order to make the selection of the motor control easier, we provide a selection
help with recommendations and alternatives for standard applications in the
subchapter entitled "
The following section briefly describe the control modes. A reference to more details can
be found at the end of each section.
V/f characteristic control (VFCplus)
The V/f characteristic control (VFCplus) is a motor control mode for standard frequency
inverter applications based on a simple and robust control process which is suitable for the
operation of machines with linear or square-law load torque characteristic (e.g. fans).
Furthermore, this motor control mode is also suitable for special motors. Due to the low
parameterisation effort, commissioning of such applications is fast and easy.
The V
min
-boost (
) and slip compensation (
) required for optimising the drive
behaviour are dimensioned for machines with power adaptations to the inverter in the
Lenze setting.
