1969 2076 The value set in the parameter
shown to the left overflowed.
This parameter is not used at
present. Set 0.
0783 1971 2078 With the closed-loop linear
motor, the conversion coefficient
parameter shown to the left is
not set. (For the Series 9080
only)
Set a value in the parameter
shown to the left.
0793 1972 2079 With the closed-loop linear
motor, the conversion coefficient
parameter shown to the left is
not set. (For the Series 9080
only)
Set a value in the parameter
shown to the left.
0843 1977 2084 A positive value is not set as the
flexible feed gear numerator.
Alternatively, the numerator of
the feed gear is greater than the
denominator.
Set a positive value as the
flexible feed gear numerator.
Alternatively, correct the
parameter so that the
numerator of the feed gear is
less than or equal to the
denominator. (For other
than parallel type separate
detectors)
0853 1978 2085 A positive value is not set as the
flexible feed gear denominator.
Set a positive value as the
flexible feed gear
denominator.

0886
1981 2088 The internal value of the
machine velocity feedback
coefficient overflowed.
Decrease the machine
velocity feedback coefficient.
Alternatively, use the
vibration-damping control
function that has an
equivalent effect.
0883 1981 2088 For an axis with a serial type
separate detector, a value
exceeding 100 is set as the
machine velocity feedback
coefficient.
For an axis with a serial type
separate detector, the upper
limit of the machine velocity
feedback coefficient is 100.
Correct the coefficient so
that it does not exceed 100.

0927
0928
1985 2092 The internal value of the
advanced preview feed-forward
coefficient overflowed.
Use the position gain
expansion function.
→ See Supplementary 3.
0996 1992 2099 The internal value for N pulse
suppression overflowed.
Decrease the value set in the
parameter shown to the left.
1123 1705 2112 Although a linear motor is used,
the AMR conversion coefficient
parameter is not input.
Set the AMR conversion
coefficient.
1183 1729 2118 With a closed-loop linear motor,
the semi-closed loop error
threshold parameter is not set.
(For the Series 9080 only)
Set the semi-closed loop
error threshold value in the
parameter shown to the left.

1736 2128 When a small value is set as the
number of velocity pulses, the
internal value of a parameter
Decrease the value in the
parameter shown to the left
