| Alarm Code |
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. |
| 06 |
The temperature sensor is abnormal. Or the temperature sensor cable is broken. |
| 07 |
The motor rotates at a speed exceeding 115% of the maximum allowable speed. |
| 09 |
The temperature of the heat sink has risen abnormally. |
| 12 |
An excessively large current flowed into the main circuit. |
| 15 |
This alarm is issued only when output switching control or spindle switching control is used. |
| 18 |
A sum check is abnormal. |
| 19 & 20 |
The offset voltage of the phase U (alarm code 19) or phase V (alarm code 20) current detection is excessively high. |
| 21 |
The specified polarity of the position sensor is incorrect. |
| 24 |
Serial communication data transferred between the CNC and SVPM contain an error. |
| 27 |
The signal of the a position coder is disconnected. |
| 29 |
An excessive load ( standard setting: load meter reading of 9.5V) 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. |
| 32 |
LSI memory for serial communication is abnormal. A check is made when the power is turned on. |
| 34 |
Parameter data outside the specified range was set. |
| 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 α position coder is generated is incorrect. |
| 42 |
The one rotation signal of the α 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 α position coder signal pulses is abnormal. |
| 50 |
A value obtained by internal calculation in spindle synchronization exceeded the allowable range. |
| 52 & 53 |
The synchronziation 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. |
| 73 |
The signal of the motor sensor is disconnected. |
| 75 |
An abnormality was detected during control program transfer processing. |
| 79 |
An abnormality was detected during control program initialization. |
| 81 |
The position where the one rotatation signal of the motor sensor is generated is incorrect. |
| 82 |
The one rotation signal of the motor sensor is not generated. |
| 83 |
The SVPM checks the pulse counts of phases A and B each time a one rotation signal is detected. |
| 84 |
The spindle sensor signal was disconnected. |
| 85 |
The one rotation signal of the spindle sensor occured in an incorrect location. |
| 86 |
No spindle sensor one rotation signal occured. |
| 87 |
A spindle sensor signal is abnormal. |
| A1 & A2 |
The control program is not running. An error was detected when the control program was running. |
| C0, C1 & C2 |
An error occured in serial communication data between the CNC and spindle amplifier module. |
| 35 |
There is a large difference between the motor speed calcualted from the position coder and the motor speed estimated with the spindle software. |
