7.2.1 Configuration
Parameter
Configuration 30 determines the assignment and basic function of the
control inputs and outputs as well as the software functions. The software of the fre-
quency 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 pa-
rameters in the third
Control level 28 (adjustment of parameter Control level 28 to
value 3).
Configuration 110, sensorless control
Configuration 110 contains the functions for variable-speed control of a 3-phase ma-
chine 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 sensor-less 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 sensor-less, 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, parallel
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. Change-over between variable-speed control and torque-dependent
control is done via a digital control input.
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 nec-
essary speed sensor feedback results in a precise speed and torque performance.
Configuration 211, field-oriented control with technology controller
Configuration 211 extends the functionality of Configuration 210 by a Technology
Controller. The Technology Controller enables a control based on parameters such as
flow rate, pressure, filling level or speed.
Configuration 230, field-orientated control with speed/torque control
Configuration 230 extends the functionality of Configuration 210 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. Change-over between variable-speed control and torque-dependent
control is done via a digital control input.
