Comments • activate_fly_2d_encoder occupies two
two 10 µs clock cycles to execute (the first part of activate_fly_2d_encoder is not a
short list command).
• activate_fly_2d_encoder is a combination of

uncorrected virtual
For the error handling, see comments of activate_fly_2d.
• Because of this combination, activate_fly_2d_encoder saves the positioning stage
movement (which is often long but may be necessary for the Processing-on-the-fly
activation without this command) from the initialization position (for example, at the
lower left corner) to the center and back again.
• Subsequently all encoder values are offset with EncX and EncY, before the
Processing-on-the-fly correction is applied. All other encoder related commands refer
to the actual encoder values and behave as before.
• If the value of EncX or EncY is not allowed (that is, the Processing-on-the-fly-corrected
virtual
activate_fly_2d_encoder is replaced by a
RTC6_PARAM_ERROR).
• If the value of ScaleX or ScaleY is not allowed (see set_fly_2d), the first part is
transferred to the board (and thus executes the encoder reset). However, the second
part is replaced by a
• With active Processing-on-the-fly correction, activate_fly_2d_encoder is a short
