Distance from the end of the deceleration dog to the first grid point
The distance from the deceleration dog to the first grid point is displayed on
the output unit.

DTH ALP NOF BZ2 BZ1 PR2 PR1
#0(PR1) : The setting of the following parameters has been changed:
Parameters 1821, 1850, 1860, 1861.
#1(PR2) : The setting of the ATS bit (bit 1 of parameter 8302) has been
changed.
#2(BZ1) : The detected APC battery voltage is 0 V (Inductosyn).
#3(BZ2) : The detected APC battery voltage is 0 V (separate position
detector).
#4(NOF) : The Inductosyn output no offset data.
#5(ALP) : Before the α pulse coder detects a full single rotation, reference
position establishment by parameters was attempted.
#6(DTH) : A controlled axis detach signal/parameter was input.
No. #7

DUA XBZ GSG AL4 AL3 AL2 AL1
#0(AL1) : An APC alarm was issued.
#2(AL3) : The detected APC battery voltage is 0 V (serial pulse coder).
#3(AL4) : An abnormal rotation speed (RCAL) was detected.
#4(GSG): The G202 signal was brought from 0 to 1.
#1(AL2) : A disconnection was detected.
#6(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.
#5(XBZ) : The detected APC battery voltage is 0 V (serial separate position
detector).
6.1.10 Inductosyn display (No. 380 and No. 381)
No.
380
Difference between the absolute position of the motor and offset data
The deviation between the absolute position of the motor and the offset data
is displayed. That is, the remainder of (M (absolute motor position) – S
(offset data)) / l(1–pitch interval) is displayed in detection units.
No.
381
Offset data from the Inductosyn
Offset data, received by the CNC at the time of macine position calculation,
is displayed in detection units.
