Servo amplifier detection error

14 TROUBLESHOOTING
14.5 List of Error Codes
Error details and causes
The synchronous parameter "[Pr.465] Current value per
cycle after main shaft gear (Initial setting)" is other than
0 to (Cam axis length per cycle - 1).
[Operation status at error occurrence]
Synchronous control does not start.
The synchronous parameter "[Pr.461] Setting method of
current value per cycle after auxiliary shaft gear" is set
to other than 0 to 2.
[Operation status at error occurrence]
Synchronous control does not start.
The synchronous parameter "[Pr.466] Current value per
cycle after auxiliary shaft gear (Initial setting)" is other
than 0 to (Cam axis length per cycle - 1).
[Operation status at error occurrence]
Synchronous control does not start.
The synchronous parameter "[Pr.462] Cam axis position
restoration object" is set to other than 0 to 2.
[Operation status at error occurrence]
Synchronous control does not start.
The synchronous parameter "[Pr.463] Setting method of
cam reference position " is set to other than 0 to 2.
[Operation status at error occurrence]
Synchronous control does not start.
• The synchronous parameter "[Pr.464] Setting method
of cam axis current value per cycle" is set to other
than 0 to 3.
• "3: Current value per cycle after auxiliary shaft gear"
is established when the auxiliary shaft does not exist.
[Operation status at error occurrence]
Synchronous control does not start.
The synchronous parameter "[Pr.468] Cam axis current
value per cycle (Initial setting)" is set other than 0 to
(Cam axis length per cycle - 1).
[Operation status at error occurrence]
Synchronous control does not start.
Cam axis current value per cycle corresponding to the
current feed value at synchronous control start could
not be restored when the synchronous parameter
"[Pr.462] Cam axis position restoration object" was "0:
Cam axis current value per cycle restoration". (Occurs
in reciprocated cam pattern)
[Operation status at error occurrence]
Synchronous control does not start.
Restoration could not be completed when the
synchronous parameter "[Pr.462] Cam axis position
restoration object" was "2: Cam axis current feed value
restoration", because the difference between the
restored cam axis current feed value and the current
feed value at synchronous control start (pulse
command unit) was larger than the servo parameter "In-
position range".
[Operation status at error occurrence]
Synchronous control does not start.
Remedy
Set within the range of 0 to (Cam axis length per cycle
- 1).
Set a value within the range of 0 to 2.
Set within the range of 0 to (Cam axis length per cycle
- 1).
Set a value within the range of 0 to 2.
Set a value within the range of 0 to 2.
• Set a value within the range of 0 to 3.
• Set other than "3: Current value per cycle after
auxiliary shaft gear" when the auxiliary shaft does
not exist.
Set within the range of 0 to (Cam axis length per cycle
- 1).
• Start synchronous control after moving the current
feed value as to fit within the stroke of two-way
operation cam pattern.
• Set the cam reference position as to fit within the
stroke of two-way operation cam pattern.
• Start synchronous control after calculating the cam
axis current feed value to be restored, using the cam
position calculation function, and moving the current
feed value.
• Set a larger setting value for the servo parameter
"In-position range", if the current value is extremely
small (such as 0).
