Travel errors Error response : “Feed STOP” see Table 11-2
3 (03) 3 (03) Traversing range beginning approached CBS
Cause
S
During traversing with soft limit switches disabled, the travers-
ing range beginning was approached.
S
The axis is located to the left of the traversing range
beginning because of actual value set.
(Traversing range:
10
9
or from range covered by absolute
encoder.)
Effect
S
Axis movement is stopped at the traversing range limit.
S
Set actual value is not executed.
Elimina-
tion Travel in the opposite direction
3 (03) 4 (04) Traversing range end approached CBS
Cause
S
During traversing with soft limit switches disabled, the travers-
ing range end was approached.
S
The axis is located to the left/right of the traversing range end
because of actual value set.
(Traversing range:
10
9
or from range covered by absolute
encoder.)
Effect
S
Axis movement is stopped at the traversing range limit.
S
Set actual value is not executed.
Elimina-
tion Travel in the opposite direction.
3 (03) 5 (05) Target position not within traversing range CBS
Cause
S
The position to be approached is outside the working range
limited by the software limit switches.
S
The rotary axis programming is specified as a reference value
which does not fall within the positive complete circle.
Effect
Elimina-
tion
S
Correct the position to be approached.
S
Alter value of software limit switch (MD).
S
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).
3 (03) 23 (17) Target velocity zero CBS
Cause
S
Zero was entered as programmed velocity.
S
No feed was programmed for positioning.
Effect
Elimina-
tion Input an allowable velocity value.
