Transmission speed changing procedure
In an initial state (0 state), the display shows the information on the error
codes, SERCOS phase, etc. Keeping the BOOT button pressed for 3
seconds (long push) it switches to a new state (state 1) that is used for
selecting the communication speed and the display shows the speed
currently selected.
In this state 1, every time this button is pressed for less than 0.8 seconds
(short push), the display shows the next communication speed value that
may be selected. Hence, apply several short pushes until the desired
speed is displayed.
Once the display shows the desired speed, apply a long push and a QP11
value will be assigned and it will be saved into the flash memory of the
module where it will also cause the unit to RESET.
Anomalous events during the procedure
Any error that comes up when saving parameters into flash memory will
be displayed with an error message on the display while the BOOT button
is pressed and then it will return to state 1 (speed selection).
Any change made to the communication speed is retained after the module
has been turned off, provided that the command to save parameters has
been previously executed successfully.
If, for any reason, the module is turned off or reset in any stage of this
procedure, when started up again, the transmission speed value given by
QP11 will be the last one that was successfully assigned during previous
changes. The speed change procedure may be ignored (without making
any changes) at any time if the command to save parameters has not been
executed.
Refer to the values that can be assigned to parameter QP11 in chapter 13
of the · man_dds_soft.pdf · manual.

Diagram of the SERCOS-II transmission speed selecting procedure.
NOTE. Any attempt to select a value other than those assigned to the
possible transmission speeds will generate an error and it will not be
selected.
NOTE. While in state 1, and after 8 seconds without pressing the “BOOT”
button, the module switches to state 0 and the display will show the initial
information.
