13.2 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)
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.
