官方故障排除步驟
Parameters: %1 = Channel number %2 = Block number %3 = Slave axis %4 = String Definitions: The option stage is inadequate for the desired function. Possible reasons: More couplings have been created than are permitted. The number of permissible leading axes has been exceeded for one or more couplings. The range of functions of one or mo re couplings has not been released. Reaction: Interpreter stop NC Start disable in this channel. Interface signals are set. Alarm display. Remedy: Buy an adequate option stage. Reduce the number of simult aneously active couplings. Reduce the number of leading axes per coupli ng or only use the released range of functions. Program Continuation: Clear alarm with the RESET key. Restart part program Diagnostics Manual (DAsl), 03/2009
