3.3 Mastership switching
Users can switch the mastership between host controller and Thunder. Before performing mastership
switching, ensure the servo drive is Fieldbus type.
Table 3.3.1
(1) Only Fieldbus servo drive supports mastership switching; standard servo drive does not
support this function.
(2) When Thunder holds the mastership, the controller will show “Off-line” and cannot
connect to servo drive. When Controller holds the mastership, Thunder only has part of
the monitoring functions and any parameter change is ineffective. To modify parameters,
switch the mastership to Thunder.
(3) If Fieldbus servo drive is power cycled, Controller automatically holds the mastership.
