4.5.11. Saving the position in controller's FRAM memory¶
Controller has a function which automatically remembers its last position. This allows one to power-off the controller after it has stopped. On the next power-on the controller will appear in the same motor position, logical position and encoder value. This will work if during the time controller was off the motor shaft was not rotated by external means.
Note. For this function to work one should wait at least 0.5 seconds after the stop before cutting the power. Position is saved even if the controller was powered off during movement, however in this case its saved position will not be exact and a new calibration will be needed.
