12. APPLICATION OF FUNCTIONS
(5) Using together with other functions
Availability of other functions during the interrupt positioning is as follows:
ITP (Interrupt positioning) is available in the program method.
Because the interrupt positioning function with MSD (Mark detection) input signal is prioritized, the
interrupt positioning function with MSD (Mark detection) can be used during the interrupt positioning
function with ITP (Interrupt positioning). However, ITP (Interrupt positioning) cannot be used during the
interrupt positioning with MSD (Mark detection).
12.3 Infinite feed function (setting degree)
When degree is set as the position data unit at the automatic operation or manual operation in the point table
method or program method, [AL. E3.1 Multi-revolution counter travel distance excess warning] does not
occur and the home position is not erased even if the servo motor rotates 32768 rev or more in the same
direction. Thus, the current position is restored after the power is cycled. For other command units, [AL. E3.1
Multi-revolution counter travel distance excess warning] occurs and the home position is erased if the servo
motor rotates 32768 rev or more in the same direction.
The following shows differences depending on the position data unit when the servo motor rotates 32768 rev
or more in the same direction.
Parameter Name
PT01 Position data unit
Note. For the servo amplifiers with software version B6 or earlier, [AL. E3.1] occurs and the home position is erased.

POINT
This function can be used with the absolute position detection system.
The infinite feed function (setting degree) is available with servo amplifiers with
software version B7 or later.
The infinite feed function (setting degree) can be used in the point table method
and the program method.
