Error name Error details and causes
Start not possible Start is requested during the forced stop of controller.
[Operation status at error occurrence]
The system does not start positioning.
Outside input axis type The setting values of the input axis parameters
setting range "[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.
Outside input axis unit setting The setting value of the input axis parameter "[Pr.321]
range Synchronous encoder axis unit setting" is outside the
setting range.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
Outside input axis unit The input axis parameter "[Pr.323] Synchronous
conversion denominator encoder axis unit conversion: Denominator" is set to 0
range or lower.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
Outside input axis length per The input axis parameter "[Pr.324] Synchronous
cycle range encoder axis length per cycle" is set to 0 or lower.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
Outside input axis smoothing The input axis parameters "[Pr.301] Servo input axis
time constant range smoothing time constant" and "[Pr.325] Synchronous
encoder axis smoothing time constant" are outside the
range of 0 to 5000.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
Outside input axis rotation The input axis parameters "[Pr.304] Servo input axis
direction restriction setting rotation direction restriction" and "[Pr.328]
range Synchronous encoder axis rotation direction
restriction" are outside the range of 0 to 2.
[Operation status at error occurrence]
The setting becomes invalid for input axis.
Input axis unit conversion Internal operation overflow occurred because the unit
overflow 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.
Speed-position switching When the input axis parameter "[Pr.300] Servo input
control start in servo input axis type" is feed current value or real current value,
axis not possible 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".
[Operation status at error occurrence]
The speed-position switching control does not start.
Synchronous encoder via • The hardware of the synchronous encoder or the
servo amplifier servo amplifier is faulty.
communication error • 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.
Synchronous encoder via The battery which the servo amplifier connected
servo amplifier battery error synchronous encoder is empty or the battery is
disconnected.
[Operation status at error occurrence]
The synchronous encoder control continues.

Remedy
Remove the cause of forced stop.
Bring the setting into the setting range.
Bring the setting into 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 the
servo command value or feedback value.
• Set "[Pr.21] Feed current value during speed
control" to "1: Update 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.
