Operating Instructions, 05/2011, A5E01071724-03
Meaning
Illegal hardware interrupt
Cause You attempted to define a hardware interrupt for a cam with a
cam number > 7.
Incorrect track number
Cause The track number is outside the range 0 to 31
Incorrect cam start
Cause The cam start is outside the traversing range
(-100 m to +100 m or -1000 m to +1000 m).
Rotary axis: The cam start is < 0 and/or greater than the end of
rotary axis.
Incorrect cam end
Cause The cam end is outside the traversing range
(-100 m to +100 m or -1000 m to +1000 m).
The cam length is not at least one pulse.
Rotary axis: The cam end is < 0 and/or greater than the end of
rotary axis.
With an inverse cam, there are not at least 4 pulses between
the cam start and cam end.
Incorrect activation time
Cause The activation time is < 0 µs. The maximum value depends on
the number of cams available (see chapter "Cam data
(Page 97)").
Incorrect lead time
1)
Cause The lead time is < 0 µs. The maximum value depends on the
number of cams available (see chapter "Cam data (Page 97)").
Too many cam sets
Cause You wanted to enter more cam records than is possible with
this number of cams.
Axis in operation
Cause You wanted to enter cam records while the cam controller is
active.
Axis parameters not assigned
Cause You want to enter cam data although not machine data are
active yet.
The error message may also be issued if you have assigned the parameter "inverted" as the count
direction in connection with an absolute encoder (SSI).
