Fanuc alarm list pdf

Alarm numbers are common to all these alarm types.

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

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. 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. Internal cooling circuit failure, Overload, Input supply voltage imbalance, IPM failure, or control supply voltage decrease of the power module. Regenerative discharge energy is too high. 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.

Conditions when performing circular interpolation start or cancel not correct. The axis set in parameter No.

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.

Correct the cause then turn on the power again. The sign of feedback data from the built—in pulse coder differs from that of feedback data from the separate detector. In the laser mode, a nibbling command or pattern command was specified. This alarm is generated to enable the cause of the servo-off state to be checked. Fault of input signal for bubble device Fault in bubble device. Any of the following alarms occurred in the operation with the simple synchronization control. Please help. Execute a correct operation. Assign TMR has parameter number that is out of correct number not to exceed the range. An unusable G code or G code corresponding to the function not provided is specified. On fanuc series 0i-mate TD.. Alternatively, abnormal spindle motor load has been detected in Cs mode. FSSB communication was disconnected suddenly. MCC is faulty. When the yellow LED is on, an error code is indicated with a 2-digit number.

When a 2-path system and multiple servo axes between paths are controlled by a multiaxis amplifier, if a servo alarm occurs on an axis belonging to another path of the same amplifier, the MCC of the amplifier goes down and SV V-READY OFF occurs on an axis belonging to the local path in the same amplifier. Perform the return to the reference position. Check that the servo interface module and servo amp are connected. Any ideas what I need to do? The value specified in the X-axis move command exceeded the positive value of stored stroke limit 1. The file name is already used. This alarm may occur in the following case: 1 The parameter No. This alarm may occur in the following case: 1 During the setting of parameter No. Check the values of the dual position conversion coefficients in parameters No. The axis belonging to another path in the same amplifier resolves the cause of the servo alarm. Any coil located at other place must be erased once, and place necessary coils in correct place.
