Error name Error details and causes
Composite main shaft gear The composite value is overflowed (sign reverse)
operation overflow because the input values of main input axis and sub
input axis are large.
[Operation status at error occurrence]
Synchronous control is immediately stopped.
Outside auxiliary shaft No. • The setting value of the synchronous parameter
range "[Pr.418] Auxiliary shaft axis No." is outside the
setting range.
• The same servo input axis No. as the output axis is
set for "[Pr.418] Auxiliary shaft axis No.".
[Operation status at error occurrence]
Synchronous control does not start.
Outside auxiliary shaft gear: The synchronous parameter "[Pr.421] Auxiliary shaft
denominator range gear: Denominator" is set to 0 or lower.
[Operation status at error occurrence]
Synchronous control does not start.
Auxiliary shaft gear operation Overflow (sign reversion) occurred in input values,
overflow because the auxiliary shaft gear ratio is too large.
[Operation status at error occurrence]
Synchronous control is immediately stopped.
Outside auxiliary shaft clutch The setting value of the synchronous parameter
control setting range "[Pr.422] Auxiliary shaft clutch control setting" is
outside the setting range.
[Operation status at error occurrence]
Synchronous control does not start.
Outside auxiliary shaft clutch The setting value of the synchronous parameter
reference address setting "[Pr.423] Auxiliary shaft clutch reference address
range setting" is outside the setting range.
[Operation status at error occurrence]
Synchronous control does not start.
Outside auxiliary shaft clutch The setting value of the synchronous parameter
smoothing method range "[Pr.428] Auxiliary shaft clutch smoothing method" is
outside the setting range.
[Operation status at error occurrence]
Synchronous control does not start.
Outside auxiliary shaft clutch The setting value of the synchronous parameter
smoothing time constant "[Pr.429] Auxiliary shaft clutch smoothing time
range constant" is outside the setting range.
[Operation status at error occurrence]
Synchronous control does not start.
Composite auxiliary shaft The composite value is overflowed (sign reverse)
gear operation overflow because the input values of main shaft and auxiliary
shaft are large.
[Operation status at error occurrence]
Synchronous control is immediately stopped.
Outside speed change gear The setting value of the synchronous parameter
range "[Pr.434] Speed change gear arrangement" is outside
the setting range.
[Operation status at error occurrence]
Synchronous control does not start.
Outside speed change ratio: The synchronous parameter "[Pr.437] Speed change
denominator range ratio: Denominator" is set to 0 or lower.
[Operation status at error occurrence]
Synchronous control does not start.
Outside speed change gear The synchronous parameter "[Pr.435] Speed change
smoothing time constant gear smoothing time constant" is set to a value other
range than 0 to 5000.
[Operation status at error occurrence]
Synchronous control does not start.

Remedy
Lower the input values of main input axis and
sub input axis.
• Set within the range.
• Do not set up the same servo input axis No.
as the output axis.
Set a value within the range of 1 to 2147483647.
• Set a smaller absolute value for the
synchronous parameter "[Pr.420] Auxiliary
shaft gear: Numerator".
• Set a larger value for the synchronous
parameter "[Pr.421] Auxiliary shaft gear:
Denominator".
• Decrease the input axis speed.
