FANUC Alarms: Alarm Codes, Error Message, Faults Index.
The magnetic pole could not be detected because the motor did not run. Or, requirements to control are not satisfied in the system. Probable causes are: 1 The connection command for an amplifier is incorrect. SV AMP. Power Supply PS : The motor regenerative power is too much. The separate detector, cable, or separate detector interface unit may be failed.
A negative value, duplicate value, or greater value than the number of control axes was set to the parameter No. The connected amplifier type is incompatible with the FSSB setting value. The axis card is thought to be defective. Or, the setting of the number of axes or the amplifier connection is in error. The connecting amplifier type is incompatible with the FSSB setting value. It is probable that an optical cable failed or a connection between the amplifier and another module failed.
Or, the connection between the CNC and the amplifier in is incorrect. T Or, in the chuck tail stock barrier, an entry to the inhibited area was made during movement in the positive direction. T Or, in the chuck tail stock barrier, an entry to the inhibited area was made during movement in the negative direction. This alarm is generated when the machine reaches the stroke end. When this alarm is not generated, feed of all axes is stopped during automatic operation.
During manual operation, only the feed of the axis on which the alarm occurred is stopped. Modify the setting of the maximum number of tool life management pairs in parameter No. This alarm may occur in the following case: 1 During the setting of parameter No. The address to assign the axis signal is incorrect. This alarm may occur in the following case: 1 The parameter No. The address to assign the spindle signal is incorrect.
Possible causes are: 1 During the set of parameter No. The parameter for setting slope compensation is incorrect. This alarm occurs in the following cases: 1 When the size relationship between the slope compensation point Nos. M The parameter for setting simple straightness compensation is incorrect. The modes include the Cs contour control, spindle positioning T series , rigid tapping, and spindle control modes. The alarm is activated if the spindle control unit does not respond correctly to the mode change command issued by the NC.
An attempt was made to select the spindle number of the system having no valid spindle. Either the cable connected to a serial spindle amplifier is broken, or the serial spindle amplifier is not connected. Check to see the following parameter. Refer to A. This alarm occurs only for the slave axis.
Change the current position or reference position to prevent this situation. First, return to the reference position on the angular axis, then return to the reference position on the perpendicular axis. The compensation per compensation point is too large or too small.
Such system is not admired. S is the linear scale with distance-coded reference marks, and the other of them is not the linear scale with distance-coded reference marks.
Perform the return to the reference position. This alarm may occur with other alarms simultaneously. In this case, other alarms must be handled first. Or, the power was supplied to the Pulsecoder for the first time. If this problem recurs after the power is turned off and then back on, the battery or cable may be defective. Replace the battery with the machine turned on. Perform zero return from a point whose distance from the zero return start position to the zero point is 2 or more revolutions of the motor.

If all of them are their parameter. This is warning. If two or more instructions with same parameter number will never be active simultaneously at one time, the Ladder program has a possibility to work correctly, however, it is recommended from safety and maintenance points of view, that all these instructions should have different parameter number with each other.
