Fanuc 2017 alarm

Below is a list of FANUC servo amplifier alarms and faults with a short description briefly describing the source of each error code.

Blinking "-". Keep the cable on the Servo Amplifier side connected. Overcurrent flowed into the input of the main circuit. Input supply voltage imbalance, IGBT defective. The main circuit power module IPM has detected an overload, overcurrent, or control supply voltage decrease, overcurrent, or control supply voltage decrease.

The input power supply is abnormal open phase or the main circuit capacitor was not recharged within the specified time. When the absolute pulse coder is used, the motor has not yet rotated through more than one turn after the first power—up.

When the magnetic contactor is turned on, the phase sequence of the power supply cannot be determined.

No LED. A first to third reference position return cannot be executed because the reference position has not yet been established. The n—th axis axis 1—8 overload signal is on. Refer to diagnostic display No. Position control system fault. Due to an NC or servo system fault in the reference position return, there is the possibility that reference position return could not be executed correctly.

Try again from the manual reference position return. Abnormal servo motor load has been detected. Alternatively, abnormal spindle motor load has been detected in Cs mode. The position deviation value when the n—th axis axis 1—8 stops is larger than the set value.

The position deviation value when the n—th axis axis 1—8 moves is larger than the set value.Please contact us if you need testing, a repair or an exchange part. Note: Alarm in background edit is displayed in the key input line of the background edit screen instead of the ordinary alarm screen and is resettable by any of the MDI key operation.

The FSSB communication cable was disconnected or broken.As a generic name for a plain-text language in which CNC machine are able to understand, G-Codes are important to understand in the manufacturing, automation and engineering spaces.

In the factory automation space, nobody likes downtime and receiving error codes.

By definition, a G Code is a computer code language that is used to guide CNC machine devices to perform specific motions. Also referred to as a fixed cycle, canned cycles are ways to effectively and efficiently perform repetitive CNC machining operations. They automate specific machining functions. To learn more about canned cycles, check out this article courtesy of zero-divide.

G-Code is the most popular programming language used for programming CNC machinery. Some G words alter the state of the machine so that it changes from cutting straight lines to cutting arcs.

Other G words cause the interpretation of numbers as millimeters rather than inches. Some G words set or remove tool length or diameter offsets. We also offer repair pricing.

Listed below are some easily-understood G-code commands in which are used for setting the speed, feed, and tool parameters. Keep in mind, the machine operates at the specified speed rate when G1 is used, G1 commands are set to operate at the set F value.

Here is an example:. The Spindle speed is almost always set in RPMs revolutions per minute.

By having up-to-speed knowledge of CNC codes, you could most definitely set yourself apart from the average Joe. He was wondering what the different codes stood for, so we wanted to go ahead and list the different alarm codes for this series. These codes apply to power supplies that start with the following prefixes. The first is if you can visibly look at the end of the shaft and see the holes on the end of the coupling.

If your shaft has one hole at the end in the very center, it is a slick shaft. If the shaft has three holes in a line, that means you have a keyed shaft. Your motor may have one of two types of labels on it, the first being a yellow FANUC sticker and the other being a silver G. FANUC sticker. All of the silver G. FANUC stickers on motors have a suffix indicating a keyed shaft, except for the tag which indicates that it is actually a slick shaft.

The pictures below show what each tag looks like with the tag.

If the part number has the tag at the end of it, it is a keyed shaft. If there is no at the end of the part number, that means it is a slick shaft.

The proper way to test a FANUC motor for a short is to first lock out the machine, remove the cable from the drive, and test all three motor phases to ground with a megohmmeter. This will test both the motor and the cable for problems. There are a number of explanations for these errors.

However, the RS cable is also another high-fail item. Ensure that you are using a cable that is known to be functional when communicating. Otherwise when you attempt to read-in or punch-out a cable, you will get an alarm that is going to indicate that the cable is incorrect, or that the port has failed.

To test whether the cable or the port has failed, take a known good cable and insert it into the RS port.

Next, set your machine up to receive a file. Next, transmit your file into the machine tool. These boards or your machine will need to be sent in for repair. What is an Axis Communications Error? What is an Excess Error Alarm and why is it caused? Generally, an Excess Error means that the machine has moved beyond its allowable tolerance.

As the machine moves, there will be some deviation. This deviation is known as the Excess. These errors can be caused by a variety of problems. For example, a dull tool can caused the axis to be pushed out of position which results in a deviation error. Debris build up can cause deviations while the machine is stopped.

Additionally, a failed servo drive can also cause deviation errors. Alarm is a very generic alarm. The CNC, which is in charge of the servos, tells the servo drives to turn on and remain on.

If for whatever reason the servo drive turns itself off without the permission from the CNC, the CNC will generate a alarm. This alarm will usually occur with other alarms, such as the Alarm. The Alarm is an alarm issued by the CNC that says a problem has been found in either the servo drive or the feedback system.

The alarm will show which axis is causing the problem. To identify the specifics of this alarm, you must go into the CNC diagnostics page.Go straight to FANUC Alarm Video When a robot system goes down the first thing the operator wants to do is quickly find out what is wrong and get the system back to work.

The teach pendant displays a variety of robot information. Each new controller model that FANUC releases offers more options for troubleshooting and customizing the information that you can view about your robot.

Active Alarms — Displays the active alarms for the system. There is a fault code displayed for each alarm.

Alarm History — Displays the last alarms. The history helps with troubleshooting the root cause of errors. By analyzing the alarms in the history, you can see if one error triggers multiple other errors. By seeing which error occurred first, you determine if fixing that error solves the other faults. Alarm Descriptions and Remedies — When you select the fault code shown on the alarm log, you will get an Alarm description showing causes and remedies.

This will help you to solve the problem or error and get the system back up and running. Alarm Reports — Available on the new RiB Plus controller is a graph showing the 5 most common faults that have occurred on your system. This is great for troubleshooting and dashboarding. This How-to Video shows how to navigate to each Alarm area on the teach pendant and then use the information to clear faults.

This takes you to the Active Alarm screen where you can see all the alarms that are triggered when the E-stop on the teach pendant is hit. For this fault it reads:. Motion Controls Robotics,….
