Configuration 410, sensorless field-oriented control
Configuration 410 contains the 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, 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, which enables the control of flow rate, pressure, contents 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, which enables the control of flow rate, pressure, contents 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.
