Velocity Control Unit A06B-6055-H212#H529

When your velocity control unit is malfunctioning, progress is stymied. Every minute lost means money wasted. Attempting to repair highly technical specialized parts on your own could be a time consuming task best worth avoiding. The expert repair service technicians at Tri Star are there to help you get your CNC machine back up and running.

Our highest priority is to repair your malfunctioning FANUC or GE FANUC parts quickly and effectively. The repair technicians at Tri Star have over 90 years of combined experience working on component level repairs of CNC machines. We have done extensive work on I/O printed circuit boards, spindle amplifiers, servo drives, power supplies and other FANUC control parts.

There is no better name on the market for FANUC and GE FANUC repair jobs than Tri Star. We take your malfunctioning part back to our headquarters in McHenry, Illinois for testing on a closed loop. Tri Star does not outsource any labor-every repair is done in our own facilities. We methodically work through our progressions and determine the problem with your CNC unit. Even if we cannot find a replaceable malfunctioning part, you are only charged a minimal clean and test fee.

Once we have diagnosed the issue, we either install a replacement part from the original manufacturer or, if it isn't available, engineer our own replacement part (sometimes a more cost-effective option).

The repair technicians at Tri Star CNC are the best in the industry. Trust in us to get your manufacturing processes humming.

Error codes & alarms

When a FANUC spindle amp alarm is thrown chances are you'll need support from professionals experienced in FANUC component repairs. Give us a call - phone support is FREE and we'll clearly define your options for parts repair or replacement:

Alarm CodeDescription
01 Spindle motor over temp
02 Actual motor speed is largely deviated from the commanded speed.
03 DC link fuse has blown
04 Detected that the 3-phase input to the main circuit of the PSM has an open phase.
07 The motor rotates at a speed exceeding 115% (standard setting) of the maximum allowable speed.
09 Temperature of the heat sink of the SPM main circuit has risen to the set value.
10 Input power voltage dropped.
11 PSM detected that the DC link voltage was excessively high.
12 Excessively large current flowed into the DC link of the main circuit.
13 Memory inside the CPU is faulty.
15 Spindle switching operation sequence was not executed correctly.
16 The memory (RAM) is faulty.
17 NVRAM is faulty.
19 The offset voltage of the phase U current detection circuit is excessively high.
20 The offset voltage of the phase V current detection circuit is excessively high.
24 The power to the CNC is turned off. (This symptom does not represent an error.) Serial communication data transferred between the CNC and spindle amplifier module contains an error.
25 Serial communication between the CNC and spindle amplifier module stopped.
26 The sensor signal (for speed control) for Cs contour control has an error.
27 The sensor signal (position coder signal) for position control is abnormal.
28 The sensor signal (for position control) for Cs contour control is abnormal.
29 An excessive load (standard setting: load meter reading of 9 V) has been applied continuously for a certain period (standard setting: 30 seconds).
30 An excessively large current is detected at the input of the 3-phase main circuit of the PSM.
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.
33 The PSM could not be charged within a specified time. PSM input has an open phase.
34 Parameter data outside the specifiable range was set.
35 The gear ratio set in a parameter exceeds the value range allowable for internal processing. This alarm is issued with a parameter related to orientation of magnetic sensor type.
36 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.
39 The position where the one-rotation signal for Cs contour control is generated is incorrect. This alarm is not issued when the parameter indicated below is not set.
40 The one-rotation signal for Cs contour control is not generated.
41 The position where the one-rotation signal of the α position coder, BZ sensor, MZ sensor, α position coder S is incorrect.
47 The count value of α position coder signal pulses is abnormal. The pulse count value of the MZ sensor or BZ sensor is abnormal.
