Cause Action
0233 1876 2023 When initialization bit 0 is set to
1, the number of velocity pulses
exceeds 13100.
Correct the number of
velocity pulses so that it is
within 13100.
0243 1891 2024 When initialization bit 0 is set to
1, the number of position pulses
exceeds 13100.
Correct the number of
position pulses so that it is
within 13100.
→ See Supplementary 1.
0434
0435
1855 2043 The internal value of the velocity
loop integral gain overflowed.
Decrease the value of the
velocity loop integral gain
parameter.
0444
0445
1856 2044 The internal value of the velocity
loop proportional gain
overflowed.
Use the function for
changing the internal format
of the velocity loop
proportional gain.
→ See Supplementary 2.
0474
0475
1859 2047 The internal value of the
observer parameter (POA1)
overflowed.
Correct the setting to (−1) ×
(desired value)/10.
0534
0535
1865 2053 The internal value of a
parameter related to dead zone
compensation overflowed.
Decrease the setting to the
extent that the invalid
parameter setting alarm is
not caused.
0544
0545
1866 2054 The internal value of a
parameter related to dead zone
compensation overflowed.
Decrease the setting to the
extent that the invalid
parameter setting alarm is
not caused.
0686
0687
0688
1961 2068 The internal value of the feed-
forward coefficient overflowed.
Use the position gain
expansion function.
→ See Supplementary 3.
0694
0695
0696
0699
1962 2069 The internal value of the velocity
feed-forward coefficient
overflowed.
Decrease the velocity feed-
forward coefficient.
0754
0755
1968 2075 The value set in the parameter
shown to the left overflowed.
This parameter is not used at
present. Set 0.
NOTE
Basically, 4-digit data is indicated as alarm detail
information. However, 3- or 5-digit data may be
indicated in the following cases:
1 When the diagnosis screen is displayed, three-digit
data is indicated.
Add 0 to the top of the three digits, and read the data
as 4-digit data.
2 When the diagnosis screen is displayed, five-digit
data is indicated.
The data displayed as Axxx on the memory screen is
indicated as 10xxx on the diagnosis screen.
