5.6.2 Control Terminals – Terminal Diagram
The control hardware and the software of the frequency inverter are freely
configurable to a great extent. Certain functions can be assigned to the control
terminals, and the internal logic of the software modules can be freely selected.
In these brief instructions, the sensor-less control and the sensor-less field oriented
control are described in Configuration 110 and Configuration 410, respectively
5.6.2.1 Configuration 110 – Sensorless Control
Configuration 110 contains the functions for variable-speed control of a 3-phase
machine in a wide range of standard applications. The motor speed is set according
to the selected ratio of the reference frequency to the necessary voltage.
