SRVO-006: Hand broken
The HBK (hand-broken) safety input tripped.
What it means
The HBK (hand-broken) safety input tripped. If the robot has a breakaway safety joint on the end-of-arm tooling, it may have actually broken away after a crash. If no safety joint is used, the HBK signal line itself is grounded or cut.
Common causes
Ranked by what technicians most often find, most likely first.
- The tooling's safety joint broke away - usually after contact with something.
- HBK signal wire in the robot connection cable grounded or disconnected.
- HBK input enabled in system config on a robot that has no safety joint wired.
How to fix it
- Hold SHIFT and press RESET to clear; while holding SHIFT, jog the robot to a position where the tooling can be safely inspected and serviced.
- Inspect the tooling and safety joint - replace or reseat it, and find out what it hit before restarting production.
- If no safety joint is used, disable the hand-broken input in SYSTEM > Config rather than leaving a floating safety input.
- Persistent alarms with good tooling point to the connection cable.
