7.2 Power Supply Contactor Sequence Circuit Board (JANCD-NTU01-#)7-47.2 Power Supply Contactor Sequence Circuit Board(JANCD-NTU01-#)The power supply contactor sequence circuit board is controlled by the major axes circuitboard (SGDR-AXA01A). The main functions of the contactor circuit board are as follows:ï Servo power supply contactor I/O circuit (dual circuit)ï Brake power supply output circuitï Overrun signal input, tool shock sensor (SHOCK) signal input, and lamp power supplyoutput circuit to the manipulatorï External overrun signal input circuit (dual circuit)ï Servo-on enable signal input circuit (dual circuit)ï Fan alarm (optional) input circuitï Fan control signal output circuitï Contactor control signal output circuit (dual circuit)ï Brake release function (Operation by programming pendant - Refer to " NX100 OPERA-TORíS MANUAL ".)" Connection for Tool Shock Sensor (SHOCK)To connect the tool shock sensor directly to the tool shock sensor signal line1. Disconnect the minus SHOCK (-) and 24VU pin terminal from the WAGO connector,the NTU01-CN07 power supply contactor unit.2. Connect the minus SHOCK (-) and 24VU pin terminals to the signal line of the toolshock sensor. Use the following pin terminals for preparing the end of the signal line.Pin Name Terminal Pin Terminal Model Signal Line Terminal ModelSHOCK- PC-2005W PC-2005M (manufactured byNICHIFU Co., Ltd.)24VU PC-2005M PC-2005W (manufactured byNICHIFU Co., Ltd.)
