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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 MD20262 $MC_SPLINE_FEED_PRECISION or
reserve more memory for the representation of the arc length polynomials. MD28540
$MC_MM_ARCLENGTH_SEGMENTS defines how many polynomial segments can be used per
block in order to approximate the arc length function.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 Con- Clear alarm with the Delete key or NC START.
tinuation:
10955 [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. This can also occur if, with
active radius compensation, a block is created in which the slave axis moves but not the master axis.
The alarm is for information only and can be suppressed by setting MD20900
$MC_CTAB_ENABLE_NO_LEADMOTION = 2.
Reaction: Alarm display.
Remedy: Alarm can be switched off via MD20900 $MC_CTAB_ENABLE_NO_LEADMOTION = 2.
Program Con- Clear alarm with NC START or RESET key and continue the program.
