1A1AH Software stroke limit
-
The setting value of the "[Da.6] Positioning address/
movement amount" exceeds "[Pr.13] Software stroke
limit lower 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.
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.
1A1BH Software stroke limit
-
In the circular interpolation with sub points designated,
the sub point exceeds "[Pr.13] Software stroke limit
lower limit value".
[Operation status at error occurrence]
At operation start: The system does not start.
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.
1A1CH New current value
not possible
The control method sets an operation pattern
(continuous path control) using new current positioning
data.
[Operation status at error occurrence]
Current value is not changed.
• Do not designate a current value changing using the
positioning data following the continuous path
control.
• Do not designate positioning data following
continuous path control using a "current value
changing".
1A1DH New current value
not possible
The operation pattern sets a "new current value" in the
control method using the data following the "continuous
path control" positioning data.
[Operation status at error occurrence]
Current value is not changed.
• Do not designate a current value changing using the
positioning data following the continuous path
control.
• Do not designate positioning data following
continuous path control using a "current value
changing".
1A1EH Continuous path
control not possible
"[Da.1] Operation pattern" is "Continuous positioning
control" or "Continuous path control" when "[Da.2]
Control method" is "Speed control" or "Position-speed
switching control".
[Operation status at error occurrence]
The system does not operate at start.
Correct the "[Da.1] Operation pattern" or "[Da.2]
Control method".
1A1FH Continuous path
control not possible
"[Da.1] Operation pattern" is "Continuous path control"
when "[Da.2] Control method" is "Fixed-feed" or
"Speed-position switching control".
[Operation status at error occurrence]
The system does not operate at start.
Correct the "[Da.1] Operation pattern" or "[Da.2]
Control method".
1A20H Continuous path
control not possible
"[Da.1] Operation pattern" is "Continuous path control"
when "[Da.2] Control method" is "Speed control",
"Fixed-feed", "Position-speed switching control" or
"Speed-position switching control".
[Operation status at error occurrence]
The system does not operate at start.
Correct the "[Da.1] Operation pattern" or "[Da.2]
Control method".
1A21H Outside operation
pattern range
The operation pattern set value is 2.
[Operation status at error occurrence]
At start: The system does 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).
(Note that the deceleration stop only occurs during the
manual pulse generator operation.)
Correct the operation pattern.
