官方故障排除步驟
Parameters: %1 = Channel number %2 = Workpiece setpoint Definitions: This alarm is activated via MD27880 $MC_PART_ COUNTER, bit 1: The number of counted workpieces ($AC_ACTUAL_PARTS or $AC_SPECIAL_PARTS ) is equal or already greater than the programmed value for the number of required workpi eces ($AC_REQUIRED_PARTS). At the same time, the channel VDI signal "Workpiece setpoint reached" is output. The value for the number of counted workpieces ($AC_ACTUAL_PARTS) is reset, whil e the value of $AC_SPECIAL_PARTS is retained. Note: The setpoint/actual comparisons of the workpieces are only made after an NC start under the condition that $AC_REQUIRED_PARTS > 0. If $AC_REQUIRED_PARTS has a negative value, all workpiece counts ac tivated through MD27880 $MC_PART_COUNTER are frozen at the values they have reached, and the nominal/actual co mparison is discontinued. Reaction: NC not ready. Interface signals are set. Alarm display. Remedy: No program interrupt. Delete alarm display. Program Continuation: Clear alarm with the Delete key or NC START.
