Only the rising edge of the servo ON signal is valid. This signal turns ON the manipulator servo power supply. The set and reset timings are shown in the following.Only the rising edge of the external start signal is valid. This signal starts the manipulator. Reset this signal with the interlock configuration that determines if operation can start and with the playback (RUNNING) signal confirming that the robot has actually started moving.When the shock sensor input signal is used, the stopping method of the robot can be specified. The stopping methods are hold stop and servo power supply off. Selection of the stopping method is set in the display of the programing
Power-on Circuit Board
The power-on circuit board is controlled by the servo control circuit board (JASP-WRCA01 ). The main functions are as follows: • Specific I/O circuit, for instance, servo power supply contactor I/O circuit and emergency stop circuit • Brake power supply circuit and its output • Overrun(OT) shock sensor(SHOCK) and lamp light power supply output to robot Connection of Shock Sensor Remove SHOCK- and +24VU from XIU-CN25 (Dynamic Connector) , and connect the shock sensor signal SHOCK- to the robot.
Connection of External Power Supply for I/O
At factory setting, the internal power supply for I/O is used. If the external power supply for I/O is used, connect it with following procedure. 1. Remove the wire connected between CN26-7 to -9 and CN26-8 to -10 of the I/O contactor unit: JZNC-XIU01 . 2. Connect +24V of the external power supply to CN26-7 and 0V to CN26-8 of the I/O contactor unit: JZNC-XIU01 .
• The internal power supply of 24V of about 1A of XRC can be used for I/O. Use external 24V power supply for higher currents and to isolate the circuit inside and outside the XRC. • The I/O power supply (+24 VU, 024 VU) has 3A fuses (FU3,FU4). • Install the external power supply outside the XRC to avoid electric noise problems. • When the internal power supply is selected, do not connect the line of the external power supply to the +24VU and 0VU terminals. The unit may malfunction if the external power supply is also connected.
