Fanuc alarm list pdf

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

Alarm numbers are common to all these alarm types. The read code that caused the TH error and how many statements it is from the block can be verified in the diagnostics screen. The number of permissible digits varies according to the function and the word. This alarm is also generated when a custom macro does not contain a reserved word, or does not conform to the syntax. This alarm is also generated if the F code instructed for the S code is set extremely small in a rigid tapping instruction as the tool cannot cut at the programmed lead. Either divide the number of programmed move axes into two blocks.

This alarm will be genera ted only when the TV check is effective Data exceeding the maximum allowable number of digits was input A numeral or the sign - was input without an address at the beginning of the b lock The address was not followed by the appropriate data but was followed by another address of EOB code Sign "-" input error sign "-" was input after a address with which it can't be used. Or two "-" signs were used. Or two decimal points were input. The alarm is generated also when a G code with which the control is not equipped as an option is commanded. An ATC cycle M06 was comman ded in canned cycle mode. Push the reset button after turning off the switch. Error on Stroke Limit Switch The movable part of machine touched the X Axis plus stroke limit switch The movable part of machine touched the X Axis minus stroke limit switch While the X Axis was moving in the plus direction, It entered into the forbidden area of the stored stroke limit 1 While the X Axis was moving in the minus direction, It entered into the forbidde n area of the stored stroke limit 1 While the X Axis was moving in the plus direction, It entered into the forbidden area of the stored stroke limit 2 While the X Axis was moving in the minus direction, It entered into the forbidde n area of the stored stroke limit 2 The movable part of the machine touched the Y axis plus stroke limit switch The movable part of the machine touched the Y axis minus stroke limit switch. Perform manual reference p oint return again The content of error register of the X axis is larger than the value allowed whi le the machine is stopped The content of error register of the Y axis is larger than the value allowed whi le the machine is moving Drift in X axis is excessive. Disconnection alarm The content of the error register of the Y axis is larger than the value allowed while the machine is stopped The content of the error register of the Y axis is larger than the value allowed while the machine is moving Drift in Y axis is excessive. Disconnection alarm The content of the error register of the Z axis is larger than the value allowed while the machine is stopped The content of the error register of the Z axis is larger than the value allowed while the machine is moving Drift in Z axis is excessive. Incorre ct settings will cause this alarm

Fanuc Alarms serve as warning signals that alert operators to the presence of a problem in the system. When an alarm goes off, it displays a specific code that indicates the cause of the issue. There are several Fanuc Alarms that an operator may encounter, and each code has a specific meaning. Faulty components or motherboard errors throw system alarms and put your machinery at a standstill. Subsequently, re—set the parameters and all other data. Servo amplifier alarm first to fourth axis. A watchdog alarm condition occurred, or a RAM parity error occurred in the axis control card. Servo amplifier alarm fifth to eighth axis. Replace the master printed circuit board SRAM module , perform all—clear operation, and set all parameter and other data again. An error occurred in the PMC.
