Overview of Alarms
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.
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Modify MD or the part program.
Program Con- Clear alarm with the RESET key in all channels. Restart part program.
tinuation:
75019
Channel %1, 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.
Reactions: - 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 fol-
lowing cancel criterion applies:
Bit 0 = 0: Cancel key
