Selection of the operating mode
The motor control mode is defined with the selection of the operating mode, see
Two different processes are available, which can be operated as follows regarding the
speed feedback:
– Without speed feedback, VFCplus: linear V/f characteristic (C6, value: 6)
– Without speed feedback, VFCplus: square-law V/f characteristic (C6, value: 8)
Sensorless vector control (SLVC)
– without speed feedback, sensorless vector control (
V/f characteristic control
The V/f characteristic control is an operating mode for standard frequency inverter
applications based on a simple and robust control process. In addition to the operation of
machines with linear or square-law load torque characteristic (e.g. fan), the control process
is also suited for high-inertia systems thanks to the use of the autoboost function. Due to
the low parameterisation effort, easy and fast commissioning can be implemented for
such applications.
