FANUC A05B-2518-C202 Teach Pendant Repair
iPendant for R-30iA controllers — the most widely installed FANUC teach pendant generation
iPendant Repair for the R-30iA Platform
The FANUC A05B-2518-C202 is the standard iPendant for robots running the R-30iA controller — one of the most widely deployed FANUC controller generations globally. From ARC Mate welding cells to M-series material handling robots, this pendant is the operator interface for thousands of active robot installations. When it fails, your entire cell stops.
The A05B-2518-C202 iPendant uses a 6.4-inch colour TFT LCD with a resistive touchscreen overlay and a full membrane keypad. After years of factory floor use, these units develop predictable failure patterns: touchscreen calibration drift, LCD backlight dimming, and membrane keypad wear are the most common. Less frequent but equally disruptive are communication board failures and power circuit issues.
Our technicians have repaired thousands of A05B-2518-C202 units and can diagnose most faults within hours. We repair at the component level, test on our in-house R-30iA controllers, and ship back a fully functional pendant — typically within 5-10 business days.

Common A05B-2518-C202 Issues We Fix
Our technicians are experienced with the specific failure patterns of the iPendant series
Touchscreen Calibration Drift
The resistive touchscreen loses accuracy after years of use, registering touches several millimetres from the actual press location. This makes precise jog operations and menu navigation unreliable. Recalibration provides temporary relief, but digitizer replacement is the lasting fix.
LCD Backlight Dimming & Failure
The TFT LCD backlight gradually loses brightness over time. In factory environments with high ambient light, a dimming backlight makes the screen unreadable long before the display actually fails. Full backlight or LCD panel replacement restores original brightness.
Membrane Keypad Wear
Frequently used keys — particularly the jog keys, deadman switch, and program execution buttons — become unresponsive or require excessive pressure. The membrane overlay hardens and the underlying contacts wear out from repetitive cycling.
Communication Errors with R-30iA Controller
COMM alarms, pendant not recognised, or intermittent disconnections during operation. Often traced to cable connector damage at the pendant end, corroded pins, or failed communication ICs on the pendant's main board.
Our Repair Approach
The A05B-2518-C202 is our most frequently repaired FANUC model. Our standard repair process includes LCD panel and backlight replacement, resistive touchscreen digitizer replacement with full calibration, membrane keypad overlay replacement, USB port repair, board-level component repair, and cable connector restoration. Every unit is tested on our R-30iA controller before return.

Frequently Asked Questions — A05B-2518-C202
Is the A05B-2518-C202 the same as the iPendant?
Yes. The A05B-2518-C202 is one of the part number variants of the FANUC iPendant, specifically designed for the R-30iA and R-30iA Mate controllers. Other iPendant variants include the C200 and C201, which differ in regional configuration but share the same core hardware. We repair all iPendant variants.
Can I use an iPendant TOUCH (A05B-2518-C370) with my R-30iA controller?
No. The iPendant TOUCH (C370 series) is designed for the R-30iB controller and is not compatible with the R-30iA. If your robot runs an R-30iA controller, you need an A05B-2518-C200/C201/C202 iPendant. Repair of your existing unit is typically faster and more cost-effective than sourcing a compatible replacement.
How common are A05B-2518-C202 faults?
Very common. The R-30iA generation is now over a decade old, and iPendant failures are one of the most frequent maintenance issues on these robot cells. Touchscreen drift, LCD dimming, and keypad wear are near-universal on units that have been in continuous production use. The good news: these are well-understood faults with reliable repair solutions.
