Transmission speed changing procedure
In an initial state (0 state), the display shows the information that already
showed in previous versions (errors, 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 QP11
will be assigned its associated value that will be saved into the flash memory
of the drive and will reset the drive.

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).
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.
Any change of the communication speed is maintained after the drive is
turned off if the command to save parameters has been previously executed
successfully.
If, for any reason, the drive 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 in 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.
NOTE. While in state 1, after 8 seconds without pressing the “boot” button,
the drive switches to 0 state and the display shows the initial information.
