B–62755EN/018.TROUBLESHOOTINGf. Interlock signal or startlock signal is inputStart lock signal is inputG0007#7#6 #5 #4 #3 #2 #1STLK#0#1 (STLK) With this signal being 1, start lock signal is input.There are a plural number of interlock functions. Parameters are set bymachine tool builders for which interlock function is used.Therefore, confirm the following parameters at first:3003#7#6 #5 #4 #3DIT#2ITX#1 #0ITL#0 (ITL) 0 : Interlock signal(*IT) is valid.#2 (ITX) 0 : Interlock signal (*ITn) is valid.#3 (DIT) 0 : Interlock signal (MITn) is valid.Confirm which interlock signal is activated by the PMC’s diagnosticfunction (PMCDGN) .1) Interlock signal (*IT) is inputG0008#7#6 #5 #4 #3 #2 #1 #0*IT#0 (*IT) : When this bit is 0, interlock signal is input.2) Interlock signal per each axis (*ITn) is inputG0130#7*IT8#6*IT7#5*IT6#4*IT5#3*IT4#2*IT3#1*IT2#0*IT1*ITnWhen the bit is 0, the corresponding axis’s interlock signal is input.3) Interlock signal per axis and direction(+/– MITn) is inputG0132#7#6 #5 #4 #3+MIT4#2+MIT3#1+MIT2#0+MIT1↓ ↓ ↓G0134 –MIT4 –MIT3 –MIT2 –MIT1*+MITnInterlock signal is input to the corresponding axis and direction with thesignal being 0.4) Controlled axis detach function is running. A detached axis isspecified for travelling.*This function is valid when CNC parameter No.1005#7=1. Forwhether this function is running or not, confirm the following signalusing PMC’s diagnostic function (PMCDGN). Check the axisconcerned.F0110#7MDTCH8#6MDTCH7#5MDTCH6#4MDTCH5#3MDTCH4#2MDTCH3#1MDTCH2#0MDTCH1When signal MDTHn is “1” ,the axis detach function is in valid.The control axis detach function becomes valid by the followingsignal issued from the PMC or a CNC side parameter. Check as in thefollowing procedure :317
