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.

The initial U value for the U phase current detection circuit is abnormal. T series;In the synchronous operation, movement is commanded by the NC program or PMC axis control interface for the synchronous axis.

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. Check arc center codes I, J and K in the program.

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.

Rt-ac88u

The multi-language display message file is invalid. Personal Growth Documents. Also look at the servo amlifier for alarm code. Delete unnecessary programs and execute program registration again. Have a solution for me.. An erroneous parameter was specified for restarting a program. Check parameters No. Do not use any other places. Refer to diagnostic display No. Any of the following errors occurred in the specified format at the programmable— parameter input. The switching MC contact status check signal and command do not match.

What do you do?

If you want to use this amplifier, reset the function bit 4 to 0. Also, check the specified file parameter format. G31 is commanded in the per revolution command when the high— speed skip option is provided. In circular interpolation by radius designation, negative value was commanded for address R. Common causes of the alarms include incorrect programming, exceeding machine limits, overload signals, and issues with ready signals between position and velocity controls. The specified group is not found. Is this content inappropriate? Any coil located at other place must be erased once, and place necessary coils in correct place. Position control system fault. The tool group commanded in the machining program is not set. GT User Manual Revision 1. T series;While a registration start command G, G, or G was being executed, another registration start command was specified for the B—axis. A parameter has been specified incorrectly. If this error occurs even when the cursor is placed at a file name, contact the FANUC service center. The infeed quantity R has not been instructed for the G block.
