15.6 Safety circuit board (JANCD-ASF01-E)
This circuit board contains dual processing circuits for safety signal and the I/O circuit for
the non safe signal.
It processes external safety signals with the dual processing circuits and control ON/OFF
of the main circuit control contactor of the power supply contactor unit (JZRCR-APU0-1)
according to conditions.
Followings are the main functions of Machine Safety I/O logic unit.
• System safety input circuit (dual circuits)
• User safety input circuit (dual circuits)
• User safety output circuit (dual circuits)
• Emergency stop signal input circuit (dual circuits)
• Servo power control signal output circuit (dual circuits)
• Non safe I/O circuit for the robot system
