Encoder value

  • The function module operates in "pseudo" closed-loop mode.
  • The encoder signal is always evaluated at the end of a travel profile and a position correction is triggered via the profile generator.
  • The encoder signal is taken into account by the controller.
  • The setpoint for the current controller is generated by the higher-level profile generator.
  • The actual position corresponds to the encoder value, normalized to position.
  • An encoder value is output.
