Setting values of input axis parameters
" [Pr.300] Servo input axis type" and
" [Pr.320] Synchronous encoder axis type"
are outside the setting range.
Setting value of the input axis parameter
" [Pr.321] Synchronous encoder axis unit
setting" is outside the setting range.
The input axis parameter " [Pr.323]
Synchronous encoder axis unit
conversion: Denominator" is set to 0 or
lower.
The input axis parameter " [Pr.324]
Synchronous encoder axis length per
cycle" is set to 0 or lower.
The input axis parameters " [Pr.301] Servo
input axis smoothing time constant" and
" [Pr.325] Synchronous encoder axis
smoothing time constant" are set other
than 0 to 5000.
The input axis parameters " [Pr.304] Servo
input axis rotation direction restriction" and
" [Pr.328] Synchronous encoder axis
rotation direction restriction" are set other
than 0 to 2.
Internal operation overflow occurred
because the unit conversion ratio (unit
conversion: Numerator / unit conversion:
Denominator) of the input axis is too large.
When the input axis parameter " [Pr.300]
Servo input axis type" is feed current
value or read current value, the speed-
position switching control is started with
the detailed parameter 1 " [Pr.21] Feed
current value during speed control" set to
other than "1:Update of feed current
value".
• The hardware of the synchronous
encoder or the servo amplifier is faulty.
• The synchronous encoder cable is
disconnected.
• Communication to the synchronous
encoder cannot be established.
The battery which the servo amplifier
connected synchronous encoder is empty
or the battery is disconnected.

Operation status at
error occurrence
The setting
becomes invalid for
input axis.
The input axis
operation is
immediately
stopped, and a
connection
becomes invalid.
The speed-position
switching control
does not start.
The connection of
synchronous
encoder axis
becomes invalid.
The synchronous
encoder control
continues.
6 - 4
Corrective action
Set a value within the setting range.
Set a value within the range of 1 to
2147483647.
Set a value within the range of 0 to
5000.
Set a value within the range of 0 to
2.
• Set a smaller unit conversion ratio
(unit conversion: Numerator / unit
conversion: Denominator) of the
input axis.
• Decrease the input axis speed.
• Set " [Pr.300] Servo input axis
type" to "Servo command value"
or "Feedback value".
• Set " [Pr.21] Feed current value
during speed control" to "1:Update
of feed current value".
• Replace the synchronous encoder
or the servo amplifier.
• Check the synchronous encoder
cable.
• Check the connected synchronous
encoder.
• Check whether the synchronous
encoder cable is faulty.
Replace the battery or check the
battery connection of the servo
amplifier.
