1981H Inching movement
amount error
The inching movement amount dose not satisfy the
setting conditions
*1
. (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.
Set a smaller inching movement amount so that the
setting condition is satisfied.
1982H Overcarrying
movement amount
overflow in manual
pulse generator
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.
• 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".
1990H Error before
simultaneous start
<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.
Normalize the simultaneous start axis.
1991H Error before
simultaneous start
<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.
Normalize the simultaneous starting own axis start
data No. and the simultaneous starting axis start data
No.(1 to 3).
1993H Software stroke
limit+
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.
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.
1994H Software stroke
limit+
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.
Set the new current value within the software stroke
limit.
