iPendant teach units, A06B servo amplifiers and αi/βi motors, A20B and A16B boards, pulse coders, backup batteries and cables — for R-J3 through R-30iB Plus, including controller generations FANUC no longer supports. Tested on our own rigs and sold with a one-year warranty.
The components we are asked for most, what they do, which cabinet they belong to, and the fault that usually brings them to us. Use it to check you are ordering the right thing before you order it.
| Part number | Component | Controller generation | Typically replaced when |
|---|---|---|---|
| A05B-2518-… | iPendant teach pendant (suffix sets variant) | R-30iA / R-30iB | Cracked screen, dead keys, failed deadman switch |
| A06B-6114-… | αiSV servo amplifier module | R-30iB | Axis alarms, overcurrent and overheat faults on one axis |
| A98L-0031-0025 | 6 V memory-backup battery, 4-pack | R-J3 / R-30iA / R-30iB | Annual replacement; ignore it and you lose SRAM and mastering |
| A06B-6114-K504 | Battery kit for the above | R-30iB | Same interval, supplied as a fitted kit |
| A06B-…-B… | αi and βi series servo motor | All generations | Bearing noise, brake failure, winding or encoder fault |
| A20B-… | Main CPU, axis and I/O boards | R-J3 / R-30iA / R-30iB | Controller will not boot, communication or I/O alarms |
| A16B-… | Printed circuit boards and backplanes | R-J3 / R-J3iB | Same, on older cabinets |
| A660-… | Encoder, motor and pendant cables | All generations | Intermittent alarms that move when the cable is flexed |
| A290-… | Mechanical parts — gears, castings, wrist components | All generations | Backlash, noise, oil leaks at a joint |
FANUC numbers carry a suffix that pins the exact variant — two iPendants with the same A05B-2518 stem are not interchangeable. Send us the number from your label and we will confirm the exact variant before quoting.
FANUC's first four characters tell you the category of the component before you look anything up. This is the single most useful thing to know when you are standing in front of an open cabinet.
| Prefix / designation | What it identifies |
|---|---|
| A05B | Complete assemblies — teach pendants, controller cabinets, mechanical units |
| A06B | Servo drives, servo motors and power supply modules (αi and βi series) |
| A16B | Printed circuit boards and backplanes, mostly older generations |
| A20B | Printed circuit boards and backplanes, mostly R-30i generations |
| A61L / A66L | Displays — LCD monitors and their communication cables |
| A660 | Cables and wiring harnesses |
| A290 | Mechanical parts for the arm — gears, castings, wrist components |
| A98L | Accessories — batteries, fuses, small consumables |
Late 1990s to mid 2000s, out of OEM support
A16B and A20B boards, teach pendants and their cables, servo amplifiers, A98L backup batteries, motor and encoder harnesses. Board-level repair is usually the realistic route here, because new stock effectively does not exist.
The generation most Indian lines are running today
iPendant units and cables, A06B servo amplifiers, αi servo motors and pulse coders, A20B main and axis boards, backup batteries, fans and transformers.
Current and recent generation
iPendant and iPendant Touch, αiSV amplifier modules (A06B-6114 family), servo motors, main boards, battery kits, I/O modules. Mostly sourcing and priority dispatch rather than obsolescence work.
Most wrong-part orders come from reading the robot model off the arm and stopping there. The controller generation matters as much as the robot.
We supply parts and we repair them, so we have no reason to push you either way. When a repair is the better answer for your situation, we say so.
| Condition | What it means | Testing | Warranty |
|---|---|---|---|
| New | Unused stock, original packaging where supplied that way | Function-checked before dispatch | 1 year from purchase |
| Refurbished | Stripped, worn components replaced, rebuilt to working spec | Full run on our test rig | 1 year from purchase |
| Tested used | Working pulled unit, cleaned and verified | Full run on our test rig | 1 year from purchase |
| Repaired (your unit) | Your own component, fault repaired at board level | Validated on the rig before return | 6 months from repair |

Hands-on, on live FANUC equipment.
Brand, model, controller generation and a photo of the label is enough to get a firm price and a real lead time.
R-J3, R-J3iB, R-30iA, R-30iB and R-30iB Plus. Older R-J3 generation cells are a regular part of our work, because they are still productive and no longer supported by FANUC.
The first four characters identify the category. A05B is complete assemblies such as teach pendants and cabinets; A06B is servo drives, motors and power modules; A16B and A20B are printed circuit boards and backplanes; A61L and A66L are displays and their cables; A660 is cables and harnesses; A290 is mechanical arm parts; A98L is accessories such as batteries and fuses.
The common memory-backup battery is the 6 V quad pack listed as A98L-0031-0025, also supplied as the A06B-6114-K504 kit. It is an annual replacement item. Letting it die costs you SRAM contents and mastering data, which turns a five-minute job into a recovery.
Yes — touch screens, membranes, deadman switches, housings and cables are all repairable at component level, tested on a rig and returned with a six-month warranty. Check the cable (A660 family) before condemning the pendant; intermittent faults are frequently the cable.
Yes. The suffix after the four-character prefix is what pins the exact variant, and two units sharing a stem are often not interchangeable. Photograph the rating plate and send us what it says rather than the stem alone.
Yes — αi and βi series servo motors with their pulse coders, and A06B amplifier modules including the A06B-6114 αiSV family. Motors are tested under load before dispatch, not just continuity-checked.
We source refurbished and tested used stock, repair the unit you already have, or re-engineer the function where the original component no longer exists. Scrapping a working R-J3 cell because a board is unavailable is almost never the cheapest answer.
Yes, anywhere in India from our Pune facility, and into Europe through our branch in Germany, with the expected lead time given in the quote.
