Operation status at error occurrence
■Description
The arc radius exceeds 536870912.
■Operation status at error occurrence
At start: The system will not operate.
During operation: The system will stop immediately.
■Description
A "0" is set for number of repetitions of the control
system "LOOP".
■Operation status at error occurrence
The system stops operation.
■Description
The setting value of ABS direction in the unit of
degree is as follows.
• Set outside the setting range.
• A figure other than "0" is set when the software
stroke limit is valid.
■Operation status at error occurrence
At start: The system will not operate.
During operation: The system decelerates to a stop.
(Note that, in the continuous positioning control and
continuous path control, the system continues
operating with the setting set at the time of start
even if the setting is changed during the operation.)
■Description
The setting value of the positioning data "M code
ON signal output timing" is outside the range.
■Operation status at error occurrence
At start: The system will 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).
■Description
The setting value of the positioning data
"Interpolation speed designation method" is outside
the range.
■Operation status at error occurrence
At start: The system will 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).
CHAPTER 15 TROUBLESHOOTING
Action/Related buffer memory address/Set
range (Setting with program)
■Action
Correct the positioning data. ( Page 391,
Section 9.2.10, Page 395, Section 9.2.11)
■Buffer memory address
Page 152, Section 5.3
■Setting range
Maximum radius: 536870912
■Action
Set 1 to 65535 for number of repetitions of the
"LOOP". ( Page 454, Section 9.2.24)
■Buffer memory address
Page 152, Section 5.3
■Setting range
LOOP to LEND: 1 to 65535
■Action
• Set the ABS setting direction in the unit of
degree within the setting range.
• Set "0" when the software stroke limits are
valid. ( Page 355, Section 9.1.5)
■Buffer memory address
• ABS setting direction in the unit of degree
Axis 1: 1550
Axis 2: 1650
Axis 3: 1750
Axis 4: 1850
■Setting range
0: Shortcut
1: ABS clockwise
2: ABS counterclockwise
■Action
• Invalidate the software stroke limit. (To
invalidate, set the software stroke limit upper
limit value to be equal to the software stroke
limit lower limit value.) ( Page 355, Section
9.1.5)
■Buffer memory address
• Software stroke limit upper limit
Axis 1: 18, 19
Axis 2: 168, 169
Axis 3: 318, 319
Axis 4: 468, 469
• Software stroke limit lower limit
Axis 1: 20, 21
Axis 2: 170, 171
Axis 3: 320, 321
