Alarm Description of Alarm/Error 01 The inside temperature of the motor is higher than the specified temperature 02 The actual motor speed is largely deviated from the commanded speed 03 The fuse of the DC link has blown [The voltage at the DC link is insufficient] This alarm is checked when emergency stop is cancelled. 06 The temperature sensor is abnormal, or the temperature sensor cable is broken. 07 The motor rotates at a speed exceeding 115% [standard setting] of the maximum allowable speed. 09 The temperature of the heat sink of the SPM main circuit has risen abnormally. This alarm is issued for SPM-15i and later.With SPM-2.2i to SPM-11i however, Alarm 12 is issued for the same cause. 12 An excessively large current flowed into the DC link of the main circuit. 15 In output switching control or spindle switching control, the switching operation sequence was not executed correctly. This is issued if one second or more elapses from the transition of a switch request signal [SPSL or RSL] until a power lead state check signal [MCFN, MFNHG, RCH or RCHHG] makes a transition. 18 A sum check is abnormal. If this alarm is issued, replace the SPM or SPM control printed-circuit board. 19 / 20 The offset voltage of the phase U [19] or phase V [20] current detection circuit is excessively high. A check is made when the power is turned on. 21 The specified polarity of the position sensor is incorrect. 24 Serial communication data transferred between the CNC and spindle amplifier module contains an error. 27 The signal of the position code is disconnected. 29 An excessive load [standard setting: load meter reading of 9 V] has been applied continuously for a certain period [standard setting: 30 seconds]. 31 The motor failed to rotate as specified, and has stopped or is rotating at a very low speed. 36 The error counter overflowed. 37 After emergency stop signal input, the motor is accelerated without being decelerated. This alarm is issued also when the motor is not deactivated
[the motor is not decelerated completely] when the acceleration/deceleration time [initial parameter setting: 10 seconds] has elapsed after emergency stop signal input.
41 The position where the one-rotation signal of the position coder is generated is incorrect. 42 The one-rotation signal of the position coder is not generated. 46 The one-rotation signal of the position coder cannot be detected normally during thread cutting. 47 The count value of position coder signal pulses is abnormal. Phases A and B for the position coder have a feedback pulse count of 4096 p/rev per spindle rotation.
The SPM checks the pulse counts of phases A and B equivalent to the position coder each time a one-rotation signal is generated.
The alarm is issued when a pulse count beyond the specified range is detected.
50 A value obtained by internal calculation in spindle synchronization exceeded the allowable range. 52 / 53 The synchronization signal [ITP] in communication data transferred to and from the CNC stopped. 54 A large current flowing in the motor for a long time was detected. 55 In spindle switching control or output switching control, a mismatch between the switching request signal [SPSL or RSL] and the power lead state check signal
As a result MCFN, MFNHG, RCH, or RCHHG continues during motor activation.
56 The cooling fan for the control circuit section has stopped. 66 An error occurred during communication [connector JX4] between spindle and amplifier. 69 This alarm can be issued only when Dual Check Safety is in use. The alarm occurs if, in safety signal mode C, the spindle motor rotation speed exceeds the safety speed. 70 This alarm can be issued only when Dual Check Safety is in use. The spindle amplifier connection status does not match the hardware setting. 71 This alarm can be issued only when Dual Check Safety is in use. A safety parameter error occurred. 72 This alarm can be issued only when Dual Check Safety is in use. The result of the spindle amplifier speed check does not match the result of the CNC check. 73 The signal of the motor sensor is disconnected. 74 This alarm can be issued only when Dual Check Safety is in use. The CPU test failed to end normally 75 This alarm can be issued only when Dual Check Safety is in use. An error occurred in the CRC test. 76 This alarm can be issued only when Dual Check Safety is in use. The spindle safety function has not been executed. 77 This alarm can be issued only when Dual Check Safety is in use. The result of the spindle amplifier axis number check does not match the result of the CNC axis number check. 78 This alarm can be issued only when Dual Check Safety is in use. The result of the spindle amplifier safety parameter check does not match the result of the CNC safety parameter check. 79 This alarm can be issued only when Dual Check Safety is in use. An abnormal operation was detected in the initial test. 81 The position where the one-rotation signal of the motor sensor is generated is incorrect. 82 The one-rotation signal of the motor sensor is not generated. 83 The SPM checks the pulse counts of phases A and B each time a one-rotation signal is generated. The alarm is issued when a pulse count beyond the specified range is detected. 84 The spindle sensor signal was disconnected. 85 The one-rotation signal of the spindle sensor occurred in an incorrect location. 86 No spindle sensor one-rotation signal occurred. 87 A spindle sensor signal is abnormal. 88 The heat sink cooling fan is not running. A, A1, A2 The control program is not running, therefore an error was detected when the control program was running. b0 An error occurred in communication between amplifier modules [SPM, SVM and PSM]. C0, C1, C2 An error occurred in serial communication data between the CNC and spindle amplifier module. C3 In spindle switching a mismatch is found between the switching request signal [SPSL] and the internal status of the motor/spindle sensor signal switching circuit [submodule SW].

What causes a rotary axis error alarm [410 411]?
Most of excess error alarms [410 411] are electro-mechanical in nature. On a rotary axis, the internal brake mechanism is worn or binding. In some cases the pneumatic valve for releasing the brake needs attention. Most of excess error alarms [410 411] are electro-mechanical in nature.
Why am I getting a 411 C axis error on my FANUC 18?
I am getting a alarm 411: c axis error on my Fanuc 18 control. How can I fix this problem? well, if you want to shotgun it you need to replace all the cables, motor, and the drive... it could be any of the three. trying claning the connections first.
How to fix servo error 1829?
If One by One, try to swap against another good-axis ServoAmp. if not may be you could adjust the par 1829 to higher but not high, do graduall till the error not appear anymore. If the machine was working correctly before then there is no point in adjusting the servo error limits for stanstill and movement. You need to find the cause first.
