FANUC Alarm 20 on A06B-6134-H303#A A customer sent us a FANUC A06B-6134-H303#A all-in-one servo drive that failed to initialize after power-on. During testing, the drive displayed Alarm 20 and could not complete its self-check. In this repair case, we will show how the fault was isolated and successfully repaired. Product
Introduction Recently, we received a FANUC 0i-MF control unit from a customer who reported an unusual problem during machine startup. According to the customer, the CNC system would power on normally, but the screen constantly jumped between pages, making the machine difficult to operate. Even more concerning, several keys appeared
Mitsubishi MDS-C1-SPH-110 Drive Alarm 0032 Successfully Repaired Recently, our repair team received a customer’s Mitsubishi MDS-C1-SPH-110 spindle drive with an Alarm 0032 fault reported on-site. The machine could not operate normally due to the alarm condition. After the unit arrived at our workshop, our engineers carried out a complete inspection
If you work with FANUC Series 31i-A CNC Controller systems long enough, sooner or later you will encounter the 701 OVERHEAT FAN MOTOR alarm. Many operators assume the machine is overheating, but in actual maintenance work, the problem is usually related to cooling fan failure rather than cabinet temperature itself.
FANUC Servo Alarm 411 Troubleshooting Real Repair Case Introduction FANUC servo alarm 411 troubleshooting can be complex, as the root cause is not always obvious. In this case study, we received two FANUC servo motors from a customer, both showing Alarm 411. Through systematic testing and cross-verification, we identified completely
If your FANUC CNC display is too dark or difficult to read, adjusting the screen brightness is often the quickest solution. In this guide, we will explain how to adjust FANUC screen brightness on: Brightness adjustment method for monochrome displays (FANUC 0i-C series as an example) Brightness adjustment method for
With continuous system updates from FANUC, the FANUC 0i-F Plus CNC control system has undergone an important upgrade. The original Plus (STEP 1) system has now been upgraded to Plus STEP 2, bringing changes not only to system performance but also to software package structure and compatibility. In earlier versions,
Introduction A servo amp—also known as a servo amplifier—is a key component in CNC machines, robotics, and industrial automation. It controls the servo motor’s speed, torque, and position, allowing precise machine movement. While many brands manufacture servo amplifiers, this guide focuses on the two most widely used and supported in
In our previous article, we introduced what CRT monitors are and how they were widely used in FANUC CNC systems. Those early display units, just like old televisions, relied on cathode ray tube technology to show machining parameters, alarms, and graphics. However, as time passes, these CRT screens often face
1. What Is CRT Monitors? A CRT monitor (Cathode Ray Tube monitor) is an early type of display device that uses electron beams and phosphor-coated screens to produce images. Before the rise of modern LCD panels, CRT monitors were the standard display technology used in computers, televisions, and industrial control
When we talk about modern industry, almost everything that moves depends on some form of electric motor. From small fans to heavy production equipment, motors play a vital role in keeping machines and factories running day and night.Understanding different motors and types helps us see how each one contributes to
1. Introduction Sometimes, the simplest functions on a FANUC system are hidden in plain sight. If you’ve ever wondered how to adjust the time or change the display language, the answer lies in a single button — but we’ll get to that in a moment. 2. When You Need to
In CNC systems, the servo amplifier is a critical component. This article focuses on the Fanuc servo amplifier alarm codes you may encounter on a Fanuc α-series servo amplifier and walks through systematic troubleshooting methods. The goal: when you see a code, you know what it means and what to
Introduction A FANUC power supply alarm is one of the most common issues that can cause CNC machines to stop unexpectedly.FANUC power supply modules are the heart of the CNC system, providing stable DC power for servo and spindle amplifiers. When a fault occurs, it can cause machine downtime and
Adding a fourth axis CNC to your existing FANUC-controlled machine can greatly expand its capabilities—allowing for more complex machining, rotary motion, and multi-side processing in one setup. If you’re still in the early stages of planning, we recommend checking out our Comprehensive Guide to Upgrading to a Four Axis CNC
1. Introduction As manufacturing demands ever more complex geometries and higher precision, traditional three‑axis CNC centers alone often fall short. By adding a rotary axis, the resulting four axis cnc configuration enables multi‑face machining in a single setup, boosting efficiency while reducing fixture errors. This article delves into the principles
