000512 New design
Absolute position data in the serial pulse coder was lost.
[This alarm occurs if the serial pulse coder is replaced, the position
feedback signal line is removed from the serial pulse coder, the
battery or
its cable is removed, or parameters are loaded into the Power Mate
as a
batch.]
Machine position must be memorized using the following method:
If a battery alarm (306) occurs in the pulse coder, recover the
normal
battery status, rotate the motor through at least one turn, then turn
the
power off on again.
(1) Execute manual reference position return only for an axis for
which
this alarm was generated.
(2) Press RESET key at the end of reference position return to
release the
alarm.
Since the reference position is different from the former one,
change the
grid shift value (PRM 1850) to correct the position.
