determines the assignment and basic function of the
control inputs and outputs as well as the software functions. The software of the
frequency inverter offers several configuration options. These differ with respect to
the way in which the drive is controlled. Analog and digital inputs can be combined
and complemented by optional communication protocols as further reference value
sources. The operating instructions describe the configurations and the relevant

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 V/f characteristic in accordance with the voltage/frequency ratio.
Configuration 111, sensorless control with technology controller
Configuration 111 extends the functionality of the sensorless control by software
functions for easier adaptation to the customer's requirements in different applica-
tions. The Technology Controller enables flow rate, pressure, level or speed control.
Configuration 410, sensorless field-oriented control
Configuration 410 contains functions for sensorless, field-oriented control of a 3-
phase machine. The current motor speed is determined from the present currents
and voltages in combination with the machine parameters. In this configuration, par-
allel connection of several 3-phase motors is possible to a limited extent only.
Configuration 411, sensorless field-oriented control
with technology controller
Configuration 411 extends the functionality of Configuration 410 by a Technology
Controller. The Technology Controller enables a control based on parameters such
as flow rate, pressure, filling level or speed.
Configuration 430, sensorless field-oriented control
with speed/torque control
Configuration 430 extends the functionality of Configuration 410 by functions for
torque-dependent, field-oriented control. The reference torque is represented as a
percentage and it is transmitted into the corresponding operational performance of
the application. The switch-over between variable-speed control is done without jerk
in operation.
Configuration 210, field-oriented control
Configuration 210 contains the functions for speed-controlled, field-oriented control
of a 3-phase machine with speed sensor feedback. The separate control of torque
and flux-forming current enables high drive dynamics with a high load moment. The
necessary speed sensor feedback results in a precise speed and torque perform-
ance.
