2068 The internal value of the
feed–forward factor over-
flowed.
Use the position gain in-
crease function.

2069 The internal value of the ve-
locity feed–forward factor
overflowed.
Decrease the velocity feed–
forward factor.
754

2075 The setting of this parameter
overflowed.
This parameter is not used
presently. Set this parame-
ter to 0.
764
765
2076 The setting of this parameter
overflowed.
This parameter is not used
presently. Set this parame-
ter to 0.
783 2078 This parameter is a manda-
tory parameter when the
closed loop is set for a linear
motor, but the setting of this
parameter is set to 0.
Set this parameter to a value
other than 0 when setting the
closed loop for a linear mo-
tor.
793 2079 This parameter is a manda-
tory parameter when the
closed loop is set for a linear
motor, but the setting of this
parameter is set to 0.
Set this parameter to a value
other than 0 when setting the
closed loop for a linear mo-
tor.
843 2084 A non–positive value is set
as the flexible feed gear nu-
merator.
Alternatively, feed gear nu-
merator > denominator.
Set a positive value as the
flexible feed gear numerator.
Alternatively, ensure that
feed gear numerator x de-
nominator. (This is not appli-
cable to a separate detector
of parallel type.)
853 2085 A non–positive value is set
as the flexible feed gear de-
nominator.
Set a positive value as the
flexible feed gear denomina-
tor.
883 2088 For an axis with a serial sep-
arate detector, a value great-
er than 100 is set as the ma-
chine velocity feedback fac-
tor.
For an axis with a serial sep-
arate detector, the machine
velocity feedback factor
must not assume a value
greater than 100. Change
the setting to a value not ex-
ceeding 100.
884

886
2088 The internal value of the ma-
chine velocity feedback fac-
tor overflowed.
Decrease the machine ve-
locity feedback factor.
Alternatively, use the vibra-
tion control function, which
has the equivalent effect.

2092 The internal value of the ad-
vanced feed–forward factor
overflowed.
Use the position gain in-
crease function.
953 2095

2395
The internal value for ma-
chine distortion compensa-
tion exceeded ±12800.
When nano interpolation is
not used, this alarm can be
avoided by setting
PRM2224#5 to 1.
