If an alarm occurs in the spindle amplifier module the ALM LED lights red in the STATUS 1 display, and the two digit 7 segment LEDs will indicate the alarm code:

Alarm CodeDescription of Alarm/Error
01The inside temperature of the motor is higher than the specified temperature.
02The actual motor speed is largely deviated from the commanded speed.
06The temperature sensor is abnormal. Or the temperature sensor cable is broken.
07The motor rotates at a speed exceeding 115% of the maximum allowable speed.
09The temperature of the heat sink has risen abnormally.
12An excessively large current flowed into the main circuit.
15This alarm is issued only when output switching control or spindle switching control is used.
18A sum check is abnormal.
19 & 20The offset voltage of the phase U (alarm code 19) or phase V (alarm code 20) current detection is excessively high.
21The specified polarity of the position sensor is incorrect.
24Serial communication data transferred between the CNC and SVPM contain an error.
27The signal of the a position coder is disconnected.
29An excessive load ( standard setting: load meter reading of 9.5V) has been applied  continuously for a certain period.
31The motor failed to rotate as specified and has stopped or is rotating at a very low speed.
32LSI memory for serial communication is abnormal. A check is made when the power is turned on.
34Parameter data outside the specified range was set.
36The error counter overflowed.
37 After emergency stop signal input, the motor is accelerated without being decelerated.
 41The position where the one rotation signal of the α position coder is generated is incorrect. 
 42The one rotation signal of the α position coder is not generated.
46The one rotation signal of the position coder cannot be detected normally during thread cutting.
47The count value of α position coder signal pulses is abnormal.
50A 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.
54A large current flowing in the motor for a long time was detected.
73The signal of the motor sensor is disconnected.
75An abnormality was detected during control program transfer processing.
79An abnormality was detected during control program initialization.
81The position where the one rotatation signal of the motor sensor is generated is incorrect.
82The one rotation signal of the motor sensor is not generated.
83The SVPM checks the pulse counts of phases A and B each time a one rotation signal is detected.
84The spindle sensor signal was disconnected.
85The one rotation signal of the spindle sensor occured in an incorrect location.
86No spindle sensor one rotation signal occured.
87A spindle sensor signal is abnormal.
A1 & A2The control program is not running. An error was detected when the control program was running.
C0, C1 & C2An error occured in serial communication data between the CNC and spindle amplifier module.
35There is a large difference between the motor speed calcualted from the position coder and the motor speed estimated with the spindle software.
