What the 0x0F0103 alarm means

Safety-related I/O (protective stop, safeguard inputs) is configured inconsistently, so the controller blocks motion until the configuration is corrected. This fault ranks high in our JAKA Zu / JAKA Pro cobots (APP) service records, and the first site inspection usually finds the source.

Most common causes

  • Safety input assigned but not wired
  • Dual-channel input sees only one channel
  • Configuration changed without matching wiring
  • External safety device wired to the wrong terminals
Field note: The first cause shows up most on real machines, so verify it before you go further.

Step-by-step field fix

  1. Open the safety I/O page and compare assignments to the real wiring
  2. Fix dual-channel inputs so both channels switch together
  3. Correct the wiring or the configuration — they must match
  4. Apply and reboot the safety configuration
  5. Function-test every safety input before production
Safety first: For JAKA 0x0f0103, this alarm is the safety circuit itself: jumpering a door switch or forcing a contactor removes the protection entirely - no protective action when something happens, and no defensible account of responsibility. The self-serviceable action is Open the safety I/O page and compare assignments to the real wiring; anything past that falls under the e-stop chain and safety circuit and needs a certified engineer.

How we diagnose safety-chain faults on site

JAKA 0x0f0103 belongs to the safety chain & e-stop family. On JAKA 0x0f0103 the failing stage is collaborative safety (collision detection, safe limits, force control) on the JAKA collaborative robot cabinet - continuity of one series loop: e-stop buttons, door switches, light curtains, safety relays and the enabling device. We start reading JAKA 0x0f0103 at the pendant and app alarm pages; codes are hexadecimal with a 0x prefix.

The chain involved in JAKA 0x0f0103 runs: e-stop / door / curtain -> safety relay (dual channel) -> controller safety input -> motor-off and brake apply.

On JAKA 0x0f0103 (field clue usually Safety input assigned but not wired) we have one hard rule: On this family we have a hard rule: no bypassing the safety loop, no forcing contactors closed, ever. Some sites jumper the door switch to keep running - that removes the entire protection function, and when something happens there is no protective action and no defensible account of responsibility. We have seen a crush injury caused by exactly that jumper, so we would rather wait for parts than do it. If a customer has already jumpered it, we restore the circuit first and then diagnose the real fault.

Frequently asked questions

QWhat does the JAKA 0x0f0103 alarm mean?

Safety-related I/O (protective stop, safeguard inputs) is configured inconsistently, so the controller blocks motion until the configuration is corrected. This fault ranks high in our JAKA Zu / JAKA Pro cobots (APP) service records, and the first site inspection usually finds the source. JAKA 0x0f0103 sits in the safety chain & e-stop family; on our work orders the highest-frequency trigger for this code is "Safety input assigned but not wired".

QCan I clear a JAKA 0x0f0103 alarm myself?

Whether JAKA 0x0f0103 clears on its own depends on the outcome of "Open the safety I/O page and compare assignments to the real wiring". Finish the flow with "Function-test every safety input before production" to confirm JAKA 0x0f0103 - do not skip it. If that step is clean, the second most frequent cause on JAKA 0x0f0103 is "Dual-channel input sees only one channel". If JAKA 0x0f0103 returns after two clears, or the checks point at Safety input assigned but not wired, stop the cell and call a professional robot repair engineer.

QA safety-chain fault like JAKA 0x0f0103 stops the line - how fast can you be here?

The commonest causes we see on JAKA 0x0f0103 are "Safety input assigned but not wired, Dual-channel input sees only one channel, Configuration changed without matching wiring", so we stock the van against those. For JAKA 0x0f0103 specifically, we stock along the loop: safety relays, common door switches, e-stop buttons, light-curtain pairs and terminal blocks. For JAKA 0x0f0103, a safety-chain fault stops the whole line, so we rank it top priority and pre-triage by phone: door switch, e-stop or relay. Before we roll, tell us what JAKA 0x0f0103 shows on the pendant and app alarm pages; codes are hexadecimal with a 0x prefix and what the machine was doing - phone or video triage is free.
