Warning
• The synchronous parameter " [Pr.405]
Main shaft 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.
• The synchronous parameter " [Pr.422]
Auxiliary shaft 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.
The synchronous parameter " [Pr.437]
Speed change ratio: Denominator" is
set to 0 or lower during synchronous
control.
The synchronous parameter " [Pr.440]
Cam No." is set to other than 0 to 256
during synchronous control.
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.
Phase compensation amount of cam
axis is equal or lower than the minimum
value (-2147483648), or exceeding the
maximum value (2147483647).

Operation status at
warning occurrence
Synchronous control
continues by the
previous main shaft
clutch control setting.
Synchronous control
continues by the
previous auxiliary
shaft clutch control
setting.
Synchronous control
continues by the
previous speed
change ratio
(Denominator).
Synchronous control
continues by the
previous cam No.
Synchronous control
continues.
The operation is
controlled with the

Corrective action
• 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 smaller cam axis phase
compensation advance time.
• Decrease the cam axis input value
speed.
