Error details and causes
The positioning start is carried out when an M code ON
signal is turned ON.
[Operation status at error occurrence]
The system does not operate at start.
The positioning start is carried out when the "[Cd.190]
PLC READY signal" is turned OFF.
[Operation status at error occurrence]
The system does not operate at start.
The positioning start is carried out when the READY
signal ([Md.140] Module status: b0) is turned OFF.
[Operation status at error occurrence]
The system does not operate at start.
• At the start of positioning, the setting value of the
"positioning start No." of the axis control data is
outside the ranges of 1 to 600, 7000 to 7004, and
9001 to 9004.
• At a Pre-reading start, the "positioning start No."
setting of the axis control data is other than 1 to 600.
[Operation status at error occurrence]
The system does not operate at start.
The setting value of ABS direction in the unit of degree
is as follows.
• Set outside the setting range when the software
stroke limit is invalid.
• A figure other than "0" is set when the software stroke
limit is valid.
[Operation status at error occurrence]
At start: The system does 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.)
The setting value of ABS direction in the unit of degree
is as follows.
• Set outside the setting range when the software
stroke limit is invalid.
• A figure other than "0" is set when the software stroke
limit is valid.
[Operation status at error occurrence]
At start: The system does 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.)
• When executing operation setting at home position
return incomplete, positioning was started at home
position return request ON.
• When executing operation setting at home position
return incomplete, control mode switching was
executed at home position return request ON.
[Operation status at error occurrence]
At start: The system does not operate.
At control mode switching: The mode is not changed.
When setting the control mode auto-shift switching
selection, the control mode auto-shift switching
parameter is outside the range.
[Operation status at error occurrence]
During positioning control: The system stops with the
setting of the detailed parameter 2 Rapid stop selection
(stop group 3).
During speed control mode: The mode is switched to
position control mode, and the system stops
immediately.
Remedy
After turning OFF the M code ON signal, start the
system.
Check the program which turns ON/OFF the "[Cd.190]
PLC READY signal", and turn ON the PLC READY
signal. Then start the system.
Check the READY ON signal, and then start the
system.
Normalize the positioning start No.
• Set the ABS setting direction in the unit of degree
within the setting range.
• Set "0" when the software stroke limits are valid.
Invalidate the software stroke limit. (To invalidate, set
the software stroke limit upper limit value to the
software stroke limit lower limit value.)
• Start after the home position return is executed.
• Switch the control mode after the home position
return is executed.
• For systems which can operate the positioning
control and speed-torque control though the home
position return request is ON, set "1" to the setting
value of the operation setting at home position return
incomplete.
Set the control mode auto-shift switching parameter
within the range and switch to the continuous operation
to torque control mode.
