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). |
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). |
