NCK alarms
75019 [Channel %1: ] CLC: error ID: %2, angle %3
Parameters: %1 = Channel number
%2 = Error ID
%3 = Angle
Definitions: The subfunction of the 3D clearance control programmed with CLC(3)
"Closed-loop control in programmable direction" reports an error:
Error ID:
1:The clearance control direction has not been defined. Probably, [ 0,0,0 ] has been
programmed for the three simulated axes specifying the direction components.
In the "angle" parameter, zero is output.
2:The max. permissible angle between the orientation of the blast tool and
the programmed control direction was exceeded.
The permissible angle is set in machine data $MC_CLC_PROG_ORI_MAX_ANGLE.
The angle triggering the alarm is output in the 3rd alarm parameter.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Enlarge the monitoring angle or modify the programming in the part program.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
75020 [Channel %1: ] CLC: position offset at lower limit %2
Parameters: %1 = Channel number
%2 = Limit value
Definitions: The position offset generated by the overlaid motion has reached the limit set in MD
$MC_CLC_SENSOR_LOWER_LIMIT or programmed with CLC_LIM(...,...).
Depending on the setting in bit 0 of MD $MC_CLC_SPECIAL_FEATURE_MASK the following cancel
criterion applies:
Bit 0 = 0: Cancel key
Bit 0 = 1: Reset key
Reaction: NC Start disable in this channel.
Alarm display.
NC Stop on alarm.
Remedy: Check position and form of the workpiece. If necessary, program further limits.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
75021 [Channel %1: ] CLC: position offset at upper limit %2
Parameters: %1 = Channel number
%2 = Limit value
Definitions: The position offset generated by the overlaid motion has reached the limit set in MD
$MC_CLC_SENSOR_UPPER_LIMIT or programmed with CLC_LIM(...,...).
Depending on the setting in bit 1 of MD $MC_CLC_SPECIAL_FEATURE_MASK the following cancel
criterion is active:
Bit 1 = 0: Cancel key
Bit 1 = 1: Reset
Reaction: NC Start disable in this channel.
Alarm display.
NC Stop on alarm.
Remedy: Check position and form of the workpiece. If necessary, program further limits.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
