Figure 48: Control Structure in Flux with Motor Feedback
In the configuration shown, parameter 1-01 Motor Control Principle is set to [3] Flux w/ motor feedb and parameter 1-00 Configuration
Mode is set to [1] Speed closed loop.
Select [1] Speed closed loop in parameter 1-00 Configuration Mode to use the resulting reference as an input for the Speed PID control.
The Speed PID control parameters are in parameter group 7-0* Speed PID Ctrl.
Select [2] Torque in parameter 1-00 Configuration Mode to use the resulting reference directly as a torque reference. Torque control
can only be selected in the flux with motor feedback (parameter 1-01 Motor Control Principle) configuration. When this mode has been
selected, the reference uses the Nm unit. It requires no torque feedback, since the actual torque is calculated based on the current
measurement of the drive.
Select [3] Process in parameter 1-00 Configuration Mode to use the process PID control for closed-loop control of a process variable (for
example, speed) in the controlled application.
