2.4. Parameters: Load and Motor2.4.1. 1-0* General SettingsDefine whether the frequency converter operates in speed mode or torque mode; and whether the internal PID control should be active or not.1-00 Configuration ModeOption: Function:Select the application control principle to be used when a Remote Reference (i.e. via analog input or fieldbus)is active. A Remote Reference can only be active when par. 3-13Reference Site is set to [0] or [1].[0] Speed open loop Enables speed control (without feedback signal from motor) with automatic slip compensation for almost con-stant speed at varying loads.Compensations are active but can be disabled in the Load/Motor par. group 1-0*.[1] Speed closed loop Enables encoder feedback from motor. Obtain full holding torque at 0 RPM.For increased speed accuracy, provide a feedback signal and set the speed PID control.[2] Torque Connects the encoder speed feedback signal to the encoder input. Only possible with “Flux with motor feedback”option, par. 1-01Motor control principle.[3] Process Enables the use of process control in the frequency converter. The process control parameters are set in par.groups 7-2* and 7-3*.1-01 Motor Control PrincipleOption: Function:Select which motor control principle to employ.[0] U/f special motor mode, for parallel connected motors in special motor applications. When U/f is selected the char-acteristic of the control principle can be edited in par. 1-55 and 1-56.[1] VVCplus Voltage Vector Control principle suitable for most applications. The main benefit of VVCplus operation is that ituses a robust motor model.[2] Flux sensorless (FC 302only)Flux Vector control without encoder feedback, for simple installation and robustness against sudden loadchanges.[3] Flux w/ motor feedback(FC 302 only)very high accuracy speed and torque control, suitable for the most demanding applications.The best shaft performance is normally achieved using either of the two Flux Vector control modesFlux sensorless [2] andFlux with encoder feedback[3].This parameter cannot be adjusted while the motor is running.1-02 Flux Motor Feedback SourceOption: Function:Select the interface at which to receive feedback from the motor.[1] * 24 V encoder A and B channel encoder, which can be connected to the digital input terminals 32/33 only. Terminals 32/33must be programmed toNo operation.[2] MCB 102 Encoder module option which can be configured in par. group 17-1*This parameter appears in FC 302 only.[3] MCB 103 Optional resolver interface module which can be configured in parameter group 17-5*[4] MCO 305 encoder 1 Encoder interface 1 of the optional programmable motion controller MCO 305.[5] MCO 305 encoder 2 encoder interface 2 of the optional programmable motion controller MCO 305.This parameter cannot be adjusted while the motor is running.FC 300 Programming Guide 2.
