DTH ALP NOF BZ2 BZ1 PR2 PR1
PR1 : The setting of the following parameters has been changed:
PRM1821, 1850, 1860, 1861.
PR2 : The setting of the PRM8302#1 (ATS) has been changed.
BZ1 : The detected APC battery voltage is 0 V (Inductosyn).
BZ2 : The detected APC battery voltage is 0 V (separate position
detector).
NOF : The Inductosyn output no offset data.
ALP : Before the α pulse coder detects a full single rotation, reference
position establishment by parameters was attempted.
DTH : A controlled axis detach signal or parameter was input.

DUA XBZ GSG AL4 AL3 AL2 AL1
AL1 : An APC alarm was issued.
AL2 : A disconnection was detected.
AL3 : The detected APC battery voltage is 0 V (serial pulse coder).
AL4 : An abnormal rotation speed (RCAL) was detected.
GSG : The
QG1617 + signal
was brought from 0 to 1.
XBZ : The detected APC battery voltage is 0 V (serial separate position
detector).
DUA : While the dual position feedback function was being used, the
difference in error between the semi–closed loop side and the
closed loop side became too large.
