For ROTAX® servo motor types and Third Party Rotative
Motors, which are operated e. g. as rotary tables always in
the same direction of rotation, it can occur that the
encoder position reaches very high positive or negative
In order to ensure that the position can be continuously
incremented in positive or negative direction, a controlled
overflow mechanism is integrated in XENAX® servo
The maximum position values correspond to
31
2 -1 = 2'147'483'647 inc in positive direction and
31
-2 =-2'147'483'648 inc in negative direction.
The overflow takes place between these two values.
Actual Position: 2'147'483'646 inc
