921
Software stroke
limit upper limit
•
The “software stroke limit upper limit value”
setting in detail parameter 1 is out of the
setting range with “degree” unit.
•
The software stroke limit upper limit value is
smaller than the software stroke limit lower
limit value with a unit other than “degree”.
•
When the zero point return detailed
parameter "absolute position restoration
selection" is "1: infinite length mode" and the
axis monitor data "absolute position
restoration mode" is "1: infinite length mode",
the software stroke limit function is valid
(software stroke limit upper limit value
software stroke limit lower limit value).
922
Software stroke
limit lower limit
•
The “software stroke limit lower limit value”
setting in detail parameter 1 is out of the
setting range with “degree” unit.
•
The software stroke limit upper limit value is
smaller than the software stroke limit lower
limit value with a unit other than “degree.”
•
When the zero point return detailed
parameter "absolute position restoration
selection" is "1: infinite length mode" and the
axis monitor data "absolute position
restoration mode" is "1: infinite length mode",
the software stroke limit function is valid
(software stroke limit upper limit value
software stroke limit lower limit value).
923
