13.7 Machine Safety Unit (JZNC-YSU01-1E)
13.7.1 Machine Safety Unit (JZNC-YSU01-1E)
This unit contains dual processing circuits for safety signal.
It processes external safety signals with the dual processing circuits and
control ON/OFF of the contactor for SERVO power supply of the contactor
unit (JZRCR-YPU) according to conditions.
Followings are the main functions of Machine Safety Unit.
• Robot specific I/O circuit (safety signal dual circuits)
• Servo-ON Enable (ONEN) Input Circuit (dual circuits)
• Overrun (OT, EXOT) Input Circuit (dual circuits)
• Programming Pendant Signal PPESP, PPDSW, etc. Input Circuit
(safety signal dual circuits)
• Contactor Control Signal Output Circuit (dual circuits)
• Emergency Stop Signal Input Circuit (dual circuits)
