Error details and cause
The value of input axis parameter "[Pr.301] Servo input
axis smoothing time constant" and "[Pr.325] Synchronous
encoder axis smoothing time constant" were set outside
the range of 0 to 5000.
The value of "[Pr.304] Servo input axis rotation direction
restriction" and "[Pr.328] Synchronous encoder axis
rotation direction restriction" were set outside the range of
0 to 2.
The overflow of internal operation (unit conversion
numerator/unit conversion denominator) occurred
because the unit conversion ratio of input axis is large.
Start speed-position switching control when the status of
"[Rq.1152 Feed current value update request command]"
is OFF, or when the input axis parameter "[Pr.300] Servo
input axis type" is the feed/actual current value.
• Encoder hardware error.
• Encoder cable is open.
• The synchronous encoder specified in system setting
differs from the synchronous encoder actually
connected.
No battery in the servo amplifier which connected the
synchronous encoder, or the battery cable is
disconnected.
The axis set in synchronous encoder via servo amplifier
does not support the synchronous encoder via servo
amplifier.
• Encoder hardware is failure when the multiple CPU
system power is ON.
• The encoder cable is disconnected when the multiple
CPU system power is ON.
• The synchronous encoder specified in system setting
differs from the synchronous encoder actually
connected when the multiple CPU system power is ON.
• Encoder hardware error.
• Encoder cable is open.
The axis that input axis parameter "[Pr.320] Synchronous
encoder axis type" has been set cannot be connected in
master CPU.
Start speed control () when input axis parameter
"[Pr.300] Servo input axis type" is not invalid.
• The setting value of synchronous parameter "[Pr.400]
Main input axis number" is outside the setting range.
• The same servo input axis number as the output axis is
set in the synchronous parameter "[Pr.400] Main input
axis number".
• The setting value of "[Pr.401] Sub input axis number" is
outside the setting range.
• The same servo input axis number as the output axis is
set in the synchronous parameter "[Pr.401] Sub input
axis number".
Set the value of synchronous parameter "[Pr.404] Main
shaft gear denominator" less than 0.
The input value is overflowed (sign reverse) because the
gear ratio of main shaft gear is large.
The value of synchronous parameter "[Pr.405] Main shaft
clutch control setting" is set outside range.
Corrective action
Set the "[Pr.301] Servo input axis type smoothing time
constant", "[Pr.325] Synchronous encoder axis smoothing
time constant" within the range of 0 to 5000.
Set the "[Pr.304] Servo input axis rotation direction
restriction", "[Pr.328] Synchronous encoder axis rotation
direction restriction" within the range of 0 to 2.
• Reduce the unit conversion ratio of input axis (unit
conversion numerator/unit conversion denominator).
• Slow down the input axis.
• Set the [Pr.300] "Servo input axis type" as the servo
command value or the feedback value.
• Start the speed-position switching control after setting
the "[Rq.1152] feed current value update command" to
ON.
• Check (module change) the encoder.
• Check the encoder cable.
• Set the synchronous encoder actually connected in the
system setting.
Replace the battery and check the servo amplifier
(module replace).
Connect the servo amplifier which supports the
synchronous encoder via servo amplifier.
• Check (module change) the encoder.
• Check the encoder cable.
• Set the synchronous encoder connected actually in the
system setting.
• Check (module change) the encoder.
• Check the encoder cable.
Keep the connection status for the input axis of the
specified master CPU.
Set the "[Pr.300] Servo input axis type to be invalid". (Use
the speed-torque control function when operating the
speed control that does not include positioning loops.)
• Set within the range.
• Set the servo input axis number that is different from the
output axis.
• Set within the range.
• Set the servo input axis number that is different from the
output axis.
Set within the range of 1 to 2147483647.
• Reduce the absolute value of synchronous parameter
"[Pr.403] Main shaft gear numerator".
• Increase the synchronous parameter "[Pr.404] Main
shaft gear denominator".
• Slow down the input axis speed.
Set within the range.
