YRC1000 bypass cables

If wiring running inside the manipulator (an internal lead) breaks, the production line stops. Bypass cables are first-aid cables for exactly that situation. They route motor power and encoder signals around the broken lead so that a stopped line can be brought back quickly.

Components​

ItemLengthRole
Bypass unit—Relays each cable
Motor power bypass cable10 mFrom the bypass unit to the motor power connector
Encoder bypass cable2 m or 3 mEncoder cable to the multi-port connector. If outfitting or a jacket means it will not reach, use the maximum-length 10 m version
Robot connection cable1 mFrom the bypass unit to the robot
Bypass cable for equipment cables10 mTo the existing equipment cables
External axis bypass cable10 mFrom the bypass unit to the existing external axis cable

For medium and large models with a payload of 50 kg or more, bypass units ordered from May 2023 onwards have a built-in encoder power supply board box. They connect differently, so check the relevant section of the manual.

Precautions​

  • These are for emergencies. Do not use them permanently.
  • Always turn off the robot controller power before connecting them, and before opening or closing the unit.
  • Connecting the temporary wiring for one axis to the wrong axis's motor can destroy equipment. Check the wiring thoroughly before turning the power on.
