公式トラブルシューティング手順

Parameters: %1 = Channel number %2 = Block number, label Definitions: The path interpolation did not stop, as required, at the end of the block, but will only decelerate to a standstill in the next block. This error situati on occurs if the stop at block change was not planned by the path interpolation or was not detected early enough. A possible cause is that the PLC changed the spindle speed when MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START > 0, and the machine has to wait until the spindle has returned to the setpoi nt range. Another possible cause is that a synchronized action needs to be finished before the path in terpolation continues. The alarm is only output if MD11400 $MN_TRACE_SELECT = 'H400'. The alarm output is normally suppressed. - MD11400 $MN_TRACE_SELECT has SIEMENS password protection. Reaction: Alarm display. Remedy: MD35500 $MA_SPIND_ON_SPEED_AT_IPO_START = 1. Program G09 before the alarm output in the block to allow the path interpolation to stop as planned. Program Continuation: Clear alarm with the Delete key or NC START.
