官方故障排除步骤
Parameters: %1 = Error component (NCK/PLC) %2 = Error code Definitions: The F master signals that the communication between the NCK and PLC is no longer working. The error code %1 specifies the cause: - %1 = PLC: The PLC does no longer execute the OB40 request. - %1 = PLC-DPM: DP master is no longer in OPERATE status. Parameter %2 provides further in formation about the error's cause: - %2 = 1,2,4: PLC processing of the OB40 not finished. Reaction: Mode group not ready. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Trigger a STOP D/E (settable via MD $MN_SPL_STO P_MODE) on all axes with safety functionality. Remedy: Extend the PROFIsafe cycle time via MD $MN_PROFISAFE_IPO_TIME_RATIO. Program Continuation: Switch control OFF - ON.
