 ### Maximum servo speed
-Currently, the maximum value to write to servo speed is 1022. Any value above (below) 1022 (-1022) is rounded down (up) on the server side.
+You can get the maximum absolute value of servo-speed-setpoints with `max_speed = bot.get_max_speed()`. Any value above (below) `max_speed` (`-max_speed`) is rounded down (up) on the server side.
 
 ### Network
 At the department of automatic control, you should be connected to the omnibots via the same router. Currently this has been done with the router with name *robotlab*, where the IP naming conventions for the robots are `192.168.0.10X` for robot with name `omniX`, i.e. omnibot `omni6` has IP `192.168.0.106`.
