Overview of Alarms
NCK alarms
10948 Channel %1 block %2 curve table %3: position jump at end of period
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Number of curve table
Definitions: 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.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Correct the part program and start it again.
Program Clear alarm with the RESET key. Restart part program
Continuation:
10949 Channel %1 block %2 curve table %3: missing master axis motion
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Number of curve table
Definitions: A slave axis motion has been programmed without a master axis motion.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Correct the part program and start it again.
Program Clear alarm with the RESET key. Restart part program
Continuation:
10950 Channel %1 calculation of arc length function too inaccurate
Parameters: %1 = Channel number
Definitions: The calculation of the arc length function could not be performed to the required accuracy.
Reaction: Alarm display.
Warning display.
Remedy: 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.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10951 Channel %1 block %2 curve table %3: following value period is zero
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Number of curve table
Definitions: --
Reaction: Alarm display.
Remedy: Ensure that the table specification is correct.
Program Clear alarm with the Delete key or NC START.
Continuation:
