During traversing with soft limit switches disabled, the travers-
ing range beginning was approached.
The axis is located to the left of the traversing range
beginning because of actual value set.
9
(Traversing range: 10 or from range covered by absolute
encoder)
Axis movement is stopped at the traversing range limit.
Set actual value is not executed.
Travel in the opposite direction
During traversing with soft limit switches disabled, the travers-
ing range end was approached.
The axis is located to the left/right of the traversing range end
because of actual value set.
9
(Traversing range: 10 or from range covered by absolute
encoder)
Axis movement is stopped at the traversing range limit.
Set actual value is not executed.
Travel in the opposite direction
The position to be approached is outside the working range
limited by the software limit switches.
The rotary axis programming is specified as a reference value
which does not fall within the positive complete circle.
Correct position to be approached.
Alter value of software limit switch (MD)
Disable limit switch monitoring!
(With the limit switches (MD21/22) disabled, the travel range
limits are established by the maximum allowable values for
the limit switches).
Zero was entered as programmed velocity.
No feed was programmed for positioning.
Input an allowable velocity value
