14.5 List of Error Codes
Error details and causes
The setting value of the positioning data "[Da.27] M
code ON signal output timing" is outside the setting
range.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/sudden stop) of the detailed
parameter 2 sudden stop selection (stop group 3).
The setting value of the positioning data "[Da.29]
Interpolation speed designation method" is outside the
setting range.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/sudden stop) of the detailed
parameter 2 sudden stop selection (stop group 3).
The number of pitches set in "[Da.10] M code/Condition
data No./Number of LOOP to LEND repetitions/Number
of pitches" of the linear axis is outside the setting range
when the helical interpolation control has been
performed.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/sudden stop) of the detailed
parameter 2 sudden stop selection (stop group 3).
The sub point address is outside the range of
-2147483648 to 2147483647 when the circular
interpolation control or helical interpolation control has
been performed with the sub point being specified.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops immediately.
The set value of the basic parameter 1 "Unit setting" is
outside the setting range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
The set value of the basic parameter 1 "Number of
pulses per rotation" is outside the setting range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
The set value of the basic parameter 1 "Movement
amount per rotation" is outside the setting range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
• The set value of the basic parameter 1 "Unit
magnification" is outside the setting range.
• "Movement amount per rotation (AL)"  "Unit
magnification (AM)" exceeds 2147483648.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
The setting value of the basic parameter 1 "Bias speed
at start" is outside the setting range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
The bias speed exceeds the speed limit value.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
The setting value of the basic parameter 2 "[Pr.8] Speed
limit value" is outside the setting range.
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: READY signal [X0] is not turned ON.
At start: The system does not operate.
Remedy
Correct the setting range of the "[Da.27] M code ON
signal output timing" within "0 to 2".
Correct the setting range of the "[Da.29] Interpolation
speed designation method" within "0 to 2".
Correct the number of pitches set in "[Da.10] M code/
Condition data No./Number of LOOP to LEND
repetitions/Number of pitches" of the linear axis within
"0 to 999".
Correct the sub address (arc address).
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
• Set AL and AM values which make "Movement
amount per rotation (AL)"  "Unit magnification (AM)"
within 2147483647, and then turn the PLC READY
signal [Y0] from OFF to ON.
• With the setting brought into the setting range, turn
the PLC READY signal [Y0] from OFF to ON.
Correct the setting value and turn the PLC READY
signal [Y0] from OFF to ON.
Set the bias speed equal to or less than the speed limit
value and turn the PLC READY signal [Y0] from
OFF to ON.
When the PLC READY signal [Y0] is not turned ON
after the setting is set within the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
