公式トラブルシューティング手順
Parameters: %1 = Channel number %2 = Action number/action name Definitions: NC start has been activated in the MDI or AUTO MATIC mode and at least one axis that needs to be referenced has not reached its reference point. Reaction: Interface signals are set. Alarm display. Remedy: Please inform the authorized personnel/service department. Via the channel-specific MD20700: $MC_REFP_NC_START_LOCK (NC Start without reference point) you can decide whether or not the axis has to be referenced before NC Start. The st art of referencing can be enabled channel-specific or axis-specific. Channel-specific reference point approach: The risi ng edge of the NC/PLC interface signal DB21-30 DBX1.0 (Activate referencing) st arts an automatic sequence which star ts the axes of the channel in the same sequence as specified in the ax is-specific MD34110 $MA_ REFP_CYCLE_NR (axis sequence channel-specific referencing). 0: The axis does not participate in channel-specific referencing, but it must be referenced for NC Start, -1: The axis does not participate in channel-specific referencing, but it need not be referenced for NC Start, 1- 8: Starting sequence for the channel-specific referencing (simultaneous start at the same no.), 1 - 31: CPU type Axis-specific referencing: Press the direction key that corresponds to the approach direction in the axis-specific MD34010 $MA_REFP_CAM_MDIR_IS _MINUS (reference point approach in minus direction). Program Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
