3.2 Parameters: 1-** Load and Motor3.2.1 1-0* General SettingsDefine whether the frequency converter operates in speedmode or torque mode, and whether the internal PIDcontrol should be active or not.1-00 Configuration ModeOption: Function:Select the application control principle to beused when a remote reference (that is viaanalog input or fieldbus) is active. A remotereference can only be active whenparameter 3-13 Reference Site is set to [0]Linked to Hand/Auto or [1] Remote.[0] Speed openloopEnables speed control (without feedbacksignal from motor) with automatic slipcompensation for almost constant speed atvarying loads.Compensations are active, but can bedisabled in parameter group 1-0* Load/Motor.Set the speed control parameters inparameter group 7-0* Speed PID Ctrl.[1] Speedclosed loopEnables speed closed-loop control withfeedback. Obtain full holding torque at 0RPM.For increased speed accuracy, provide afeedback signal and set the speed PIDcontrol. Set the speed control parameters inparameter group 7-0* Speed PID Ctrl.[2] Torque Enables torque closed-loop control withfeedback. Only possible with Flux with motorfeedback option, parameter 1-01 Motor ControlPrinciple.NOTICEThis is valid for FC 302 only.[3] Process Enables the use of process control in thefrequency converter. Set the process controlparameters in parameter groups 7-2* ProcessCtrl. Feedb. and 7-3* Process PID Ctrl.[4] Torque openloopEnables the use of torque open loop in VVC+mode (parameter 1-01 Motor Control Principle).Set the torque PID parameters in parametergroup 7-1* Torque PI Control.[5] Wobble Enables the wobble functionality inparameter 30-00 Wobble Mode toparameter 30-19 Wobble Delta Freq. Scaled.[6] SurfaceWinderEnables the surface winder control specificparameters in parameter groups 7-2* ProcessCtrl. Feedb. and 7-3* Process PID Ctrl.1-00 Configuration ModeOption: Function:[7] ExtendedPID SpeedOLSpecific parameters in parameter groups 7-2*Process Ctrl. Feedb. to 7-5* Ext. Process PID Ctrl.[8] ExtendedPID SpeedCLSpecific parameters in parameter groups 7-2*Process Ctrl. Feedb. to 7-5* Ext. Process PID Ctrl.[9] Positioning NOTICEThis option is available only withsoftware version 48.XX.Activates the positioning mode.[10] Synchroni-zationNOTICEThis option is available only withsoftware version 48.XX.Activates the synchronization mode.1-01 Motor Control PrincipleOption: Function:NOTICEThis parameter cannot be adjustedwhile the motor is running.Select which motor control principle toemploy.[0]*U/f Special motor mode, for parallel connectedmotors in special motor applications. WhenU/f is selected, the characteristic of thecontrol principle can be edited inparameter 1-55 U/f Characteristic - U andparameter 1-56 U/f Characteristic - F.[1] VVC+ Voltage vector control principle is suitable formost applications. The main benefit of VVC+operation is that it uses a robust motormodel.[2] FluxsensorlessFlux vector control without encoder feedback,for simple installation and robustness againstsudden load changes.NOTICEThis is valid for FC 302 only.[3] Flux w/motor feedbHigh accuracy speed and torque control,suitable for the most demanding applications.NOTICEThis is valid for FC 302 only.The best shaft performance is normally achieved usingeither of the 2 flux vector control modes [2] Flux sensorlessand [3] Flux with encoder feedback.Parameter Descriptions VLT® AutomationDrive FC 301/30234 Danfoss A/S © 01/2018 All rights reserved.
