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). |
| 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. . |
| 18 |
A sum check is abnormal. |
| 19 / 20 |
The offset voltage of the phase U (19) or phase V (20) current detection circuit is excessively high. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 70 |
This alarm can be issued only when Dual Check Safety is in use. |
| 71 |
This alarm can be issued only when Dual Check Safety is in use. |
| 72 |
This alarm can be issued only when Dual Check Safety is in use. |
| 73 |
The signal of the motor sensor is disconnected. |
| 74 |
This alarm can be issued only when Dual Check Safety is in use. |
| 75 |
This alarm can be issued only when Dual Check Safety is in use. |
| 76 |
This alarm can be issued only when Dual Check Safety is in use. |
| 77 |
This alarm can be issued only when Dual Check Safety is in use. |
| 78 |
This alarm can be issued only when Dual Check Safety is in use. |
| 79 |
This alarm can be issued only when Dual Check Safety is in use. |
| 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. |
| 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). |
