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. |

29 | An excessive load ( standard setting: load meter reading of 9.5V) 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. |
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. 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 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. 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 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. |
