Error details and causes
Setting values of input axis parameters "[Pr.300] Servo
input axis type" and "[Pr.320] Synchronous encoder
axis type" are outside the setting range.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
Setting value of the input axis parameter "[Pr.321]
Synchronous encoder axis unit setting" is outside the
setting range.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
The input axis parameter "[Pr.323] Synchronous
encoder axis unit conversion: Denominator" is set to 0
or lower.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
The input axis parameter "[Pr.324] Synchronous
encoder axis length per cycle" is set to 0 or lower.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
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.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
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.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
Internal operation overflow occurred because the unit
conversion ratio (unit conversion: Numerator/unit
conversion: Denominator) of the input axis is too large.
[Operation status at error occurrence]
The input axis operation is immediately stopped, and a
connection becomes invalid.
When the input axis parameter "[Pr.300] Servo input
axis type" is current feed value or read current value,
the speed-position switching control is started with the
detailed parameter 1 "[Pr.21] Current feed value during
speed control" set to other than "1:Update of current
feed value".
[Operation status at error occurrence]
The speed-position switching control does not start.
• 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.
[Operation status at error occurrence]
The connection of synchronous encoder axis becomes
invalid.
The battery which the servo amplifier connected
synchronous encoder is empty or the battery is
disconnected.
[Operation status at error occurrence]
The synchronous encoder control continues.
• Setting value of the synchronous parameter "[Pr.400]
Main input axis No." is outside the setting range.
• The same servo input axis No. as the output axis is
set in the synchronous parameter "[Pr.400] Main
input axis No.".
[Operation status at error occurrence]
Synchronous control does not start.
Remedy
Set a value within the setting range.
Set a value within the setting range.
Set a value within the range of 1 to 2147483647.
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] Current feed value during speed control"
to "1:Update of current feed 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.
• Set within the range.
• Do not set up the same servo input axis number as
the output axis.
