Operating Instructions ACU
10.7 Configuration
Configuration 30 determines the assignment and basic function of the control inputs and outputs as
well as the software functions. The software of the frequency inverters offers various 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. The Operating
Instructions describe the following configurations and the relevant parameters in the third Control
Level 28 (set parameter Control Level 28 to value 3).
Configuration 110, sensor-less control (SLC)
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, SLC w. Technology Contr.
Configuration 111 extends the functionality of the sensorless control by software functions for easier
adaptation to the customer's requirements in different applications. Depending on the application,
the technology controller may be used, which enables the control of flow rate, pressure, contents
level or speed.
Configuration 410, DMR
Configuration 410 contains the functions for sensorless, field-oriented control of an asynchronous
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, DMR
w. Technology Contr
Configuration 411 extends the functionality of Configuration 410 by a Technology Controller, which
enables a control based on parameters such as flow rate, pressure, contents level or speed.
Configuration 430, DMR
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 jerk-free during operation.
Configuration 210, FOC
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 dynamism with a high load moment. The necessary speed sensor feedback
results in a precise speed and torque performance.
Configuration 211, FOC w. Technology Contr.
Configuration 211 extends the functionality of Configuration 210 by a Technology Controller, which
enables a control based on parameters such as flow rate, pressure, contents level or speed.
Configuration 230, FOC
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 jerk-free during operation.
Configuration 510, FOC Syn. Speed Controlled
Configuration 510 contains the functions for speed-controlled, field-oriented control of a
synchronous machine with speed sensor feedback. The separate control of torque and flux-forming
current enables high drive dynamism with a high load moment. The necessary speed sensor
feedback results in a precise speed and torque performance.
