1 Spot Welding Application Using a Motor Gun1.4 System Setting (Motor Gun)1-291.4.2 I/O Signals for a Motor Gun1.4.2.1 Major I/O signal (Motor Gun)Table 1-1: Input Signals to YRC1000Signal Contents To StandardSettingSetting DisplayWELD COMPLETE Shows that the welder completedthe welding normally. Used as aconfirmation signal for welding instruction(SVSPOT, SVSPOTMOV) and manual spotwelding.After this signal is input, the weldingsequence is completed, and the operationmoves to the next step.Welder IN13 Welder I/FRefer tochapter 1.4.2.2DRY TIP DRESS(WITHOUT PRESSING)DRY TIP DRESS(WITHOUT DRESSING)Use to perform the TIP DRESS instruction(SVDRESMOV) without pressing ordressing.Interlockboard, etc.Unused I/O AllocationRefer tochapter 1.4.2.3TMR COOL WTR ERR Monitors an abnormal state of the coolingwater for the welder. When this signal isinput, an alarm occurs to stop themanipulator. The servo power supply staysON.Cooling waterflow switchIN9 Pseudo InputSignalRefer tochapter 1.4.2.4GUN COOL WTR ERR Monitors an abnormal state of the coolingwater for the gun. When this signal is input,an alarm occurs to stop the manipulator.The servo power supply stays ON when thealarm occurs.Cooling waterflow switchIN10 Pseudo InputSignalRefer tochapter 1.4.2.4TRANS THERMO ERR This alarm signal from the gun transformeris input directly into the DX100. This signalis normally ON (normally closed) and whenit is OFF, an alarm occurs. The servopower supply stays ON when the alarmoccurs.GuntransformerIN11 Pseudo InputSignalRefer tochapter 1.4.2.4WELD ON/OFF(from PLC)Inputs the WELD ON/OFF selector switchstatus from a PLC such as the interlockboard. The WELD ON/OFF signal is outputto the welder according to this signal andthe manipulator status. When this signal isinput (ON), the state of the WELD ON/OFFsignal to the welder becomes OFF, andwelding is not done.Interlockboard, etc.#20022 Pseudo InputSignalRefer tochapter 1.4.2.439 of 198
