7.2 Signal flow
[7-1] Signal flow - encoder evaluation
Internal variables of the motor control (oscilloscope signals)
• The red numbers in brackets listed in the signal flow stand for internal variables of the motor
control, which you can record by means of the Oscilloscope for purposes of diagnostics and
documentation. ( 611)
MI_... = output signals of the motor interface.  Internal interfaces | "LS_MotorInterface" system block ( 277)
* Set position and setpoint speed are calculated from the basic function that is currently active.
