14.5 List of Error Codes
Error details and causes
At the start of positioning, a current speed (-1) is set for
the command speed of the positioning data to be
initially executed.
[Operation status at error occurrence]
The operation does not start at positioning start.
The current speed is set by speed control.
[Operation status at error occurrence]
The operation does not start at positioning start.
The current speed is set for speed-position or position-
speed switching control.
[Operation status at error occurrence]
The operation does not start at positioning start.
When "[Pr.20] Interpolation speed designation method"
performs a linear interpolation in setting a "composite
speed", the axis movement amount for each positioning
30
data exceeds 1073741824(2 ).
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops immediately.
The positioning address is -360.00000 or less or
360.00000 or more using INC instruction, where the
control unit is set to "degree" and "[Pr.12] Software
stroke limit upper limit value" is not equal to "[Pr.13]
Software stroke limit lower limit value".
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops immediately.
When an arc is interpolated by the designation of the
center point, a difference between a radius of start
pointcenter point and a radius of end pointcenter
point exceeds the parameter "Circular interpolation
error allowable limit".
[Operation status at error occurrence]
At start: The circular interpolation control by center point
designation is not executed.
During operation: The system stops immediately.
The setting value of the "[Da.6] Positioning address/
movement amount" exceeds "[Pr.12] Software stroke
limit upper limit value".
[Operation status at error occurrence]
At operation start: The system does not operate.
In the analysis of new current value: Current value is
not changed.
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.
In the circular interpolation with sub points designated,
the sub point exceeds "[Pr.12] Software stroke limit
upper limit value".
[Operation status at error occurrence]
At operation start: The system does not start.
Remedy
Normalize the positioning data.
Normalize the positioning data.
Normalize the positioning data.
Review the positioning address.
Review the positioning address.
• Correct the center point address (arc address)
• Correct the end address (positioning address)
• Correct the circular interpolation error allowable limit
value.
At operation start, during operation: Correct the "[Da.6]
Positioning address/movement amount".
At operation start: Set the current feed value within the
software stroke limit by the manual control operation.
At operation start, during operation: Correct the "[Da.6]
Positioning address/movement amount" and the
"[Da.7] Arc address".
At operation start: Set the current feed value within the
software stroke limit by the manual control operation.
