When the same alarm is detected by the servo system, bit 4 (PRM) of DGN
No. 0203 is set to 1.
AXS : In parameter No. 1023 (servo axis number), a value that exceeds
the range of 1 to the number of controlled axes (such as 4 instead
of 3), or nonsequential value is set.
DIR : In parameter No. 2022, used for specifying the direction of
rotation of the motor, a valid value (111 or 111) has not been set.
PLS : In parameter No. 2024, used for specifying the number of
position feedback pulses per motor rotation, an invalid value,
such as 0 or a negative value, has been set.
PLC : In parameter No. 2023, used for specifying the number of velocity
feedback pulses per motor rotation, an invalid value, such as 0
or a negative value, has been set.
MOT : In parameter No. 2020, used for specifying the motor model, an
invalid value has been set.
6.1.7 Positional error display (No. 300)
No.
300
Position error of an axis in detection unit
The positional error is displayed in Least command units.
6.1.8 Machine position display (No. 301)
No.
301
Distance from reference position of an axis in detection unit
The machine position from the reference point is displayed in least command
units.

#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.
#3(BZ2) : The detected APC battery voltage is 0 V (separate position
detector).
#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.
