1FN1 linear motor
If the EnDat serial number
read from the measuring system
is not equal to P1025, then P1017
is automatically set to 1
When the enable signals are present, a rotor position
identification routine is immediately carried-out. If the
rotor position identification was not successful,
the appropriate fault message is output. If the
causes of the fault are removed and the
fault message acknowledged, a new
identification attempt is made.

1FN3 linear motor
If the EnDat serial number read from
the measuring system is not equal to
P1025, then P1017 is not set and
Alarm 604 is displayed
("motor encoder is not adjusted")
Limitations for
motion–based rotor
position identification fulfilled?
No, limitations
not fulfilled
The angular commutation offset must be
determined by making the appropriate measurem.
