Operating Instruction - Frequency Inverter 230V / 400V ... - opis.cz

8.7 ConfigurationThe Configuration 30 determines the assignment and basic function of the controlinputs and outputs as well as the software functions. The software of the frequencyinverters offers various configuration options. These differ with respect to the way inwhich the drive is controlled. Analog and digital inputs can be combined and complementedby optional communication protocols. The operating instructions describe thefollowing configurations and the relevant parameters in the third Control level 28(adjustment of parameter Control level 28 to value 3).Configuration 110, sensorless controlConfiguration 110 contains the functions for variable-speed control of a 3-phase machinein a wide range of standard applications. The motor speed is set according tothe V/f characteristic in accordance with the voltage/frequency ratio.Configuration 111, sensorless control with technology controllerConfiguration 111 extends the functionality of the sensor-less control by softwarefunctions for easier adaptation to the customer's requirements in different applications.Depending on the application, the technology controller may be used, whichenables the control of flow rate, pressure, contents level or speed.Configuration 410, sensorless field-oriented controlConfiguration 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 andvoltages in combination with the machine parameters. In this configuration, parallelconnection of several 3-phase motors is possible to a limited extent only.Configuration 411, sensorless field-oriented controlwith Technology ControllerConfiguration 411 extends the functionality of Configuration 410 by a TechnologyController, which enables the control of flow rate, pressure, contents level or speedConfiguration 430, sensorless field-oriented controlwith speed/torque controlConfiguration 430 extends the functionality of Configuration 410 by functions fortorque-dependent, field-oriented control. The reference torque is represented as apercentage and it is transmitted into the corresponding operational performance ofthe application. Change-over between variable-speed control and torque-dependentcontrol is done via a digital control input.Configuration 210, field-oriented controlConfiguration 210 contains the functions for speed-controlled, field-oriented control ofa 3-phase machine with speed sensor feedback. The separate control of torque andflux-forming current enables high drive dynamism with a high load moment. The necessaryspeed sensor feedback results in a precise speed and torque performance.Configuration 230, field-orientated control with speed/torque controlConfiguration 230 extends the functionality of Configuration 210 by functions fortorque-dependent, field-oriented control. The reference torque is represented as apercentage and it is transmitted into the corresponding operational performance ofthe application. Change-over between variable-speed control and torque-dependentcontrol is done via a digital control input.02/06 75
