9.2
Infinite feed function
Outline
When this function is used in an absolute position detection system, even if the servo motor rotates 32768 rev or more in the
same direction, [AL. 0E3.1 Multi-revolution counter travel distance exceeded warning] will not occur and the home position will
not be erased. Therefore, the current position will be restored after the power is cycled. When this function is not used, if the
servo motor rotates 32768 rev or more in the same direction, [AL. 0E3.1] will occur and the home position will be erased.
Setting method
Set [Pr. PT85.0 Infinite feed function selection] to "1".
Servo parameter
PT85.0
When the servo motor rotates 32768 rev or more
The following table shows whether [AL. 0E3.1] will occur, the home position will be erased, and the current position will be
restored when the servo motor rotates 32768 rev or more.

*1 When [Pr. PC29.5 Absolute position counter warning [AL. 0E3.1] selection] is set to "0" (disabled), [AL. 0E3.1] will not occur and the
home position will not be erased. However, if "0" is set while the unit is other than "degree", the current position will not be restored
correctly after the power is cycled. As this will result in an incorrect current position value, set [Pr. PC29.5] to "1" (enabled).
