75015 Channel %1 block %2 CLC(0) with active TOC
Parameters: %1 = Channel number
%2 = Block number
Definitions: The 3D clearance control has been switched off with CLC(0) while tool radius compensation is still
active (G41/G42). Since CLC(0) empties the internal block buffer and accepts the current traversed
position offset of the clearance control as a "contour jump" in the interpreter, TRC must be deactivated
when this command is issued.
Reaction: Interpreter stop
Alarm display.
Remedy: Modify part program: Switch off active G41/G42 before CLC(0) or do not switch of clearance control,
but just "freeze" temporarily (CLC_GAIN=0.0) or cancel the position offset mechanically with CLC(-1).
Program Clear alarm with the RESET key. Restart part program
Continuation:
75016 Channel %1 block %2 CLC: orientation changed for TRAFOOF
Parameters: %1 = Channel number
%2 = Block number
Definitions: 1. The 2D/3D clearance control has been switched off before the transformation. The tool direction
according to G17/G18/G19 has been applied as the control direction. Switching on the transformation
with rotary axis settings that define a different tool orientation requires an orientation step change and
is therefore rejected.
2. The transformation has been switched off temporarily (TRAFOOF) while clearance control is still
active. When the transformation is switched on again, the tool orientation must be the same as when
it was switched off, i.e. the rotary axes must not be moved while the transformation is deactivated.
Reaction: NC Start disable in this channel.
Alarm display.
NC Stop on alarm.
Remedy: Modify part program: Do not switch on the clearance control until the transformation is already active
or make sure that the required conditions relating to orientation are observed.
Program Clear alarm with the RESET key. Restart part program
Continuation:
75018 Channel %1, block %2 CLC in programmable direction, error ID: %3
Parameters: %1 = Channel number
%2 = Block number
%3 = Error ID
Definitions: The subfunction of the 3D clearance control programmed with CLC(3)
"Closed-loop control in programmable direction" reports an error:
Error ID:
0:CLC(3) was programmed without having set the corresponding option bit
or without having entered an axis screen with three validly configured, simulated
axes in MD $MC_CLC_PROG_ORI_AX_MASK.
1:The plane in which the closed-loop control direction is to be re-oriented, has not
been defined. Probably, two directions programmed one after the other, are
anti-parallel.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Modify MD or the part program.
Program Clear alarm with the RESET key in all channels. Restart part program.
