504
Outside linear
movement amount
range
• When the parameter "interpolation speed
designation method" performs a linear
interpolation in setting a "composite
speed", the axis movement amount for
each positioning data exceeds
1073741824(2
30
).
• 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 software stroke
limit upper limit is not equal to the
software stroke limit lower limit.
At start : The system does not
operate.
During operation : The system stops
immediately.
506
Large arc error
deviation
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". At start : The circular interpolation
control by center point
designation is not
executed.
During operation : The system stops
immediately.
507 Software stroke limit+
• The positioning is executed at a position
exceeding the upper limit of the software
stroke limit.
• The positioning address and the new
current value exceed the upper limit of the
software stroke limit.
• In the circular interpolation with sub points
designated, the sub point exceeds the
upper limit of the software stroke limit.
• During the speed control mode/the torque
control mode, the feed current value
exceeded the upper limit of the software
stroke limit.
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 rapid stop selection (stop group 3)
in the detailed parameter 2 when the
feed current value or feed machine
value during manual control is outside
the software stroke limit range.
At the speed control mode/
the torque control mode:
The system switches to the position
control mode and stops immediately
when the feed current value is outside
the software stroke limit range.
508 Software stroke limit–
• The positioning is executed at a position
exceeding the lower limit of the software
stroke limit.
• The positioning address and the new
current value exceed the lower limit of the
software stroke limit.
• In the circular interpolation with sub points
designated, the sub point exceeds the
lower limit of the software stroke limit.
• During the speed control mode/the torque
control mode, the feed current value
exceeded the lower limit of the software
stroke limit.
