352 Detail number for invalid servo parameter setting alarm
DGN
Indicates information that can be used to identify the location (parameter)
and cause of an invalid servo parameter setting alarm (servo alarm No.
417).
This diagnosis information is valid when the following conditions are
satisfied.
D Servo alarm No. 417 has occurred.
D Bit 4 of diagnosis No. 203 (PRM) = 1
See the following table for the displayed detail numbers and the
corresponding causes. For further detail information that could be used
to take measures, refer to FANUC AC Servo Motor αi series Parameter
Manual (B–65270EN).

Cause Measure
0233 2023 A value specified as the number of veloc-
ity pulses is greater than 13100 when ini-
tialization bit 0 = 1.
Decrease the value specified as the num-
ber of velocity pulses to within 13100.
0243 2024 A value specified as the number of posi-
tion pulses is greater than 13100 when
initialization bit 0 = 1.
Decrease the value specified as the num-
ber of position pulses to within 13100.

2043 The internal value of the velocity loop in-
tegration gain has overflowed.
Decrease the value specified in the veloc-
ity loop integration gain parameter.
0444
0445
2044 The internal value of the velocity loop pro-
portional gain has overflowed.
Use a function for changing the internal for-
mat of the velocity loop proportional gain.
0474
0475
2047 The internal value of the observer param-
eter (POA1) has overflowed.
Change the setting to: (–1) × (desired
setting)/10
0534
0535
2053 The internal value of the dead zone com-
pensation parameter has overflowed.
Decrease the setting until the invalid pa-
rameter setting alarm will not occur any
longer.
0544
0545
2054 The internal value of the dead zone com-
pensation parameter has overflowed.
Decrease the setting until the invalid param-
eter setting alarm will not occur any longer.

2068 The internal value of the feedforward co-
efficient has overflowed.
Use the position gain magnification func-
tion.
0694
0695
0696
0699
2069 The interval value of the velocity feedfor-
ward coefficient has overflowed.
Decrease the velocity feedforward coeffi-
cient.
