Channel %1 block %2 curve table %3: contour not continuous
%1 = Channel number
%2 = Block number, label
%3 = Number of curve table
The contour in a curve table must be continuous. Incontinuity can occur, for example, as a
result of activating a transformation.
- Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Correct the part program and start it again.
Clear alarm with the RESET key. Restart part program.
Channel %1 block %2 curve table %3: position jump at end of period
%1 = Channel number
%2 = Block number, label
%3 = Number of curve table
A periodic curve table was defined in which the position of the following axis at the end of
the table was different to the position at the start of the table.
- Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Correct the part program and start it again.
Clear alarm with the RESET key. Restart part program.
Channel %1 block %2 curve table %3: missing master axis motion
%1 = Channel number
%2 = Block number, label
%3 = Number of curve table
A slave axis motion has been programmed without a master axis motion.
- Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Correct the part program and start it again.
Clear alarm with the RESET key. Restart part program.
Channel %1 calculation of arc length function too inaccurate
%1 = Channel number
The calculation of the arc length function could not be performed to the required accuracy.
- Alarm display.
- Warning display.
The calculation of the arc length function could not be performed to the required accuracy
during active polynomial interpolation. Either increase MD SPLINE_FEED_PRECISION
or reserve more memory for the representation of the arc length polynomials. MD
MM_ARCLENGTH_SEGMENTS defines how many polynomial segments can be used
per block in order to approximate the arc length function.
Clear alarm with NC START or RESET key and continue the program.
