Error details and causes
The inching movement amount dose not satisfy the
*1
setting conditions . (The setting value is large.)
[Operation status at error occurrence]
The inching operation is not carried out when the
inching movement amount exceeds a JOG speed limit
at the time of inching start.
The movement amount which exceeds the detailed
parameter 2 "Manual pulse generator speed limit value"
is generated continuously and the "Amount of the
manual pulser driving carrying over movement"
exceeds tolerance (-2147483648 to 2147483647).
[Operation status at error occurrence]
The system decelerates to a stop.
<When multiple axes are started and controlled
simultaneously>
• The partner axis for simultaneous start is BUSY.
• The partner axis for simultaneous start is not present.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The operation is terminated.
<When multiple axes are started and controlled
simultaneously>
• The same axis number is set to multiple simultaneous
start axes.
• The own axis number is set to a simultaneous start
axis.
• The number of simultaneous start axes is outside the
setting range of 2 to 4.
• The "Simultaneous starting axis start data No." of the
start axis is 0 or is outside the setting range.
• The "Simultaneous starting axis start data No." of the
start axis and the partner axis for simultaneous start
is 0 or is outside the setting range.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The operation is terminated.
The command position exceeds the upper limit of the
software stroke limit.
[Operation status at error occurrence]
At operation start: The system does not operate.
During operation:
• The system stops immediately when the positioning
address during position control (including position
control in speed-position switching control or position-
speed switching control) is switched to the data
outside the software stroke limit range.
• During speed control (including speed control in
speed-position switching control or position-speed
switching control), the system stops at the setting
(normal deceleration stop only) of sudden stop
selection (stop group 3) in the detailed parameter 2
when the current feed value or machine feed value
during manual control is outside the software stroke
limit range.
At speed control mode/torque control mode/continuous
operation to torque control mode: The system switches
to the position control mode and stops immediately
when the current feed value is outside the software
stroke limit range.
The new current value exceeds the upper limit of the
software stroke limit.
[Operation status at error occurrence]
In the analysis of new current value: Current value is
not changed.
Remedy
Set a smaller inching movement amount so that the
setting condition is satisfied.
• Adjust input pulses so as not to occur the movement
amount, which exceeds the detailed parameter 2
"Manual pulse generator speed limit value",
continuously.
• Change the detailed parameter 2 "Manual pulse
generator speed limit mode" to a value other than "2:
Output over value of speed limit later".
Normalize the simultaneous start axis.
Normalize the simultaneous starting own axis start
data No. and the simultaneous starting axis start data
No.(1 to 3).
At operation start: Set the current feed value within the
software stroke limit by the manual control operation.
At speed control mode/torque control mode/continuous
operation to torque control mode: Review the operation
so that the current feed value does not exceed the
software stroke limit.
Set the new current value within the software stroke
limit.
