%2 = Block number
Definitions: One of the limits for the position offset of the clearance control programmed with
CLC_LIM( ...,...) is greater than the permissible limitation set in the associated MD.
$MC_CLC_SENSOR_LOWER_LIMIT[ 1 ] or $MC_CLC_SENSOR_UPPER_LIMIT[ 1 ].
Reactions: - Interpreter stop
- Alarm display.
Remedy: Modify parts program. Extend limitation in appropriate machine date.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:

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 compensa-
tion 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.
Reactions: - Interpreter stop
- Alarm display.
Remedy: Modify part program: Switch off active G41/G42 before CLC(0) or do not switch of clear-
ance control, but just "freeze" temporarily (CLC_GAIN=0.0) or cancel the position offset
mechanically with CLC(-1).
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:

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.
Reactions: - 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:

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)
