Operation status at error occurrence
■Description
• The positioning data No. tried to be executed is
outside the ranges of 1 to 600, 7000 to 7004, and
9001 to 9004.
• The designation of a JUMP destination is
executed currently.
• The designation of a JUMP destination is outside
the ranges of 1 to 600.
■Operation status at error occurrence
The positioning data is not executed.
■Description
• At the start of positioning, a current speed (-1) is
set for the command speed of the positioning
data to be initially executed.
• The current speed is set by speed control.
• The current speed is set for speed-position
switching control or position-speed switching
control.
■Operation status at error occurrence
At the start of positioning, operation does not start.
■Description
• When the "composite speed" has been set in
"Interpolation speed designation method" of the
parameter or positioning data and a linear
interpolation control is performed, the axis
movement amount set for each positioning data
30
exceeds 1073741824 (2 ).
• 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.
■Operation status at error occurrence
At start: The system will not operate.
During operation: The system stops immediately.
