7.2 Power Supply Contactor Sequence Circuit Board
(JANCD-NTU01-#)
The power supply contactor sequence circuit board is controlled by the major axes circuit
board (SGDR-AXA01A). The main functions of the contactor circuit board are as follows:
• Servo power supply contactor I/O circuit (dual circuit)
• Brake power supply output circuit
• Overrun signal input, tool shock sensor (SHOCK) signal input, and lamp power supply
output circuit to the manipulator
• External overrun signal input circuit (dual circuit)
• Servo-on enable signal input circuit (dual circuit)
• Fan alarm (optional) input circuit
• Fan control signal output circuit
• Contactor control signal output circuit (dual circuit)
• Brake release function (Operation by programming pendant - Refer to " NX100 OPERA-
TOR’S MANUAL ".)
" Connection for Tool Shock Sensor (SHOCK)
To connect the tool shock sensor directly to the tool shock sensor signal line
1. 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 tool
shock sensor. Use the following pin terminals for preparing the end of the signal line.
