3.3 Parameters: 1-** Load and Motor3.3.1 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 (i.e. via analoginput or fieldbus) is active. A remote referencecan only be active when 3-13 Reference Site isset to [0] Linked to Hand/Auto or [1] Remote.[0] Speedopen loopEnables speed control (without feedback signalfrom motor) with automatic slip compensationfor almost constant speed at varying loads.Compensations are active, but can be disabledin parameter group 1-0* Load/Motor. The speedcontrol parameters are set in parameter group7-0* Speed PID Ctrl.[1] SpeedclosedloopEnables speed closed loop control with feed-back. Obtain full holding torque at 0 RPM.For increased speed accuracy, provide afeedback signal and set the speed PID control.The speed control parameters are set inparameter group 7-0* Speed PID Ctrl.[2] Torque Enables torque closed loop control with feed-back. Only possible with Flux with motorfeedback option, parameter 1-01 Motor ControlPrinciple. FC 302 only.[3] Process Enables the use of process control in thefrequency converter. The process controlparameters are set in parameter groups 7-2*Process Ctrl. Feedb. and 7-3* Process PID Ctrl.[4] Torqueopen loopEnables the use of torque open loop in VVC+mode (parameter 1-01 Motor Control Principle).The torque PID parameters are set 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 group 7-2* Process Ctrl.Feedb. and 7-3* Process PID Ctrl.[7] ExtendedPID SpeedOLSpecific parameters in parameter group 7-2*Process Ctrl. Feedb. to 7-5* Ext. Process PID Ctrl.[8] ExtendedPID SpeedCLSpecific parameters in parameter group 7-2*Process Ctrl. Feedb. to 7-5* Ext. Process PID Ctrl.1-01 Motor Control PrincipleOption: Function:NOTICEThis parameter cannot be adjusted whilethe motor is running.Select which motor control principle toemploy.[0] U/f Special motor mode, for parallel connectedmotors in special motor applications. When U/fis selected the characteristic of the controlprinciple can be edited in parameter 1-55 U/fCharacteristic - U and parameter 1-56 U/fCharacteristic - F.[1] VVC+ Voltage Vector Control principle suitable formost applications. The main benefit of VVC+operation is that it uses a robust motor model.[2] FluxsensorlessFlux Vector control without encoder feedback,for simple installation and robustness againstsudden load changes. FC 302 only.[3] Flux w/motor feedbVery high accuracy speed and torque control,suitable for the most demanding applications.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.NOTICEAn overview of possible combinations of the settings inparameter 1-00 Configuration Mode andparameter 1-01 Motor Control Principle can be found inchapter 4.1.3 Active/Inactive Parameters in Different DriveControl Modes.1-02 Flux Motor Feedback SourceOption: Function:NOTICEThis parameter cannot be adjustedwhile the motor is running.Select the interface for which to receivefeedback from the motor.[1] * 24V encoder A and B channel encoder, which can beconnected to the digital input terminals32/33 only. Terminals 32/33 must beprogrammed to No operation.[2] MCB 102 Encoder module option, which can beconfigured in parameter group 17-1* Inc.
