OM1: O5 toggles when the position is reached

Example:

There are 2 settings for O5 "Position reached" which are set with P227:

P227 bit 423 ="1"	Meaning / function
OM124	O5 toggles when the position is reached
	O5 toggles after every new positioning when position is
	reached.
P227 bit 4 ="0"
P14>0, small	O5 = "1": nominal value reached and lag error < P14
values	O5="1" if set point generator has finished the ramp and the lag
(small in comparison	error is smaller than P14.
with the process	If the lag error after O5="1" is greater than P14, then O5 = "0"
travel)	until the lag is again less than P14.
OM2
P14>>0, large	O5 = "1": nominal value reached (independent of P14)
value	O5 = "1" as soon as the set point generator has finished the
(large in comparison	ramp and stays at "1" until the start of the next positioning
with process travel)	move.
OM3

Functional description:

O5 is toggled (=changed, i.e. from O5="1" to O5="0", from O5="0" to O5="1") after every positioning move (set point generator has reached target position) .

When an error occurs (Exx is indicated), O5 stays at the current value. Can be adjusted using: P227 bit 4 ="1"
