官方故障排除步驟
Parameters: %1 = Channel number %2 = Axis name, spindle number %3 = Block number Definitions: The probe programmed under the keyword MEAS or MEAW is already deflected and has switched. For a further measuring operation, the probe signal must first be canceled ( quiescent state of the probe). The axis display is of no signifi cance at the present time but an axis-specific evaluation has been planned for later stages of development. Reaction: Local alarm reaction. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: Verify the starting position of the measuring operat ion or check the probe signals in the PLC interface DB10 DBX107.0 / 107.1 (Probe actuated key 1/key 2). Are the cables and connectors in good order? Diagnostics Manual (DAsl), 03/2009 Program Continuation: Clear alarm with the RESET key. Restart part program
