Warning name Error details and causes
Input axis phase Phase compensation amount of input axis is equal or
compensation amount over lower than the minimum value (-2147483648), or
exceeding the maximum value (2147483647).
[Operation status at warning occurrence]
The input axis operation continues. It is controlled with
the minimum or maximum value.
Input axis rotation direction Rotation direction restriction amount of input axis is
restriction amount over equal or lower than the minimum value (-2147483648),
or exceeding the maximum value (2147483647).
[Operation status at warning occurrence]
The input axis operation continues. It is controlled with
the minimum or maximum value.
Input axis speed display over Monitor speed display of input axis is equal or lower
than the minimum value (-2147483648), or exceeding
the maximum value (2147483647).
[Operation status at warning occurrence]
The input axis operation continues. The minimum or
maximum value is displayed as the speed display of
monitor data.
Synchronous encoder via Voltage of the servo amplifier battery connected with a
servo amplifier battery synchronous encoder decreased to 3.2 V or less.
warning [Operation status at warning occurrence]
The synchronous encoder control continues.
Outside main shaft clutch • The synchronous parameter "[Pr.405] Main shaft
control setting range clutch control setting" was set to outside the setting
range during the synchronous control.
• The synchronous parameter "[Pr.405] Main shaft
clutch control setting" was set from a setting other
than "No Clutch" to "No Clutch" during the
synchronous control.
[Operation status at warning occurrence]
Synchronous control continues by the previous main
shaft clutch control setting.
Outside auxiliary shaft clutch • The synchronous parameter "[Pr.422] Auxiliary shaft
control setting range clutch control setting" was set to outside the setting
range during the synchronous control.
• The synchronous parameter "[Pr.422] Auxiliary shaft
clutch control setting" was set from a setting other
than "No Clutch" to "No Clutch" during the
synchronous control.
[Operation status at warning occurrence]
Synchronous control continues by the previous
auxiliary shaft clutch control setting.
Outside speed change ratio The synchronous parameter "[Pr.437] Speed change
denominator range ratio: Denominator" is set to 0 or lower during
synchronous control.
[Operation status at warning occurrence]
Synchronous control continues by the previous speed
change ratio (Denominator).
Outside cam No. range The synchronous parameter "[Pr.440] Cam No." is set
to other than 0 to 256 during synchronous control.
[Operation status at warning occurrence]
Synchronous control continues by the previous cam
No.
Cam not registered When changing the synchronous parameter "[Pr.440]
Cam No.", the cam data of the changed cam No. does
not exist on the Cam open area during synchronous
control.
[Operation status at warning occurrence]
Synchronous control continues by the previous cam
No.
Cam axis length per cycle Set the value of synchronous parameter "Cam axis
outside range length per cycle" ([Pr.439]) less than 0.
[Operation status at warning occurrence]
Synchronous control continues by the previous cam
axis length per cycle.

Remedy
• Set a smaller phase compensation advance
time.
• Decrease the input axis speed.
• Confirm the enabled direction of the rotation
direction restriction setting. (The setting may
be reversed.)
• Check if the input axis moves to the reverse
direction of the enabled direction.
• Set a lower value if the number of decimal
places for speed command setting is available
in the input axis setting.
• Switch the units from minute to second if the
speed command time unit setting is available
in the input axis setting.
• Decrease the input axis speed.
Replace the battery.
• Set a value within the range.
• Do not change the settings other than "No
Clutch" to "No Clutch".
• Set a value within the range.
• Do not change the settings other than "No
Clutch" to "No Clutch".
Set a value within the range of 1 to 2147483647.
Set a value within the range of 0 to 256.
Specify the cam No. of an existing cam data.
Set a value within the range of 1 to 2147483647.
