SPINDLE AMP - AC A06B-6055-H112

We realize not everyone is quite as obsessed with CNC equipment repair as we are, but if you could put together a wish list of everything you've always wanted in a repair service provider there's a good chance it would look something like this:

  1. Experienced Professionals
    Your FANUC A06B-6055-H112 AC Spindle Amp will be in good hands when you send it to Tri Star CNC. With over 90 years of collective experience and a founding partner who spent 15 years at FANUC and designed many of their test benches, it's safe to say we know what we're doing.
  2. OEM Or Better Parts
    Our experienced technicians will thoroughly diagnose your unit and replace any parts which need replacing with OEM or better quality parts. While they're at it, they will replace any electrical components known to have a high failure rate and give your unit a thorough cleaning to remove any dust and dirt which could shorten its useful life.
  3. Priority Service
    We know downtime costs you money. So, workload permitting, we treat every job as a priority.
  4. All Work Done In-House
    Unlike some repair services who ship their customers' equipment to foreign countries and then mark up the cost to make a profit, we do all our own repair work in-house. Sanjay and Carlos may do great work in their countries, but nobody knows FANUC and GE FANUC like us - and nobody cares more about doing a great job than Tri Star.
  5. The Best Warranty Around
    We back our work with a one-year parts and repair warranty on the entire assembly repair. We don't just cover the parts and labor other companies cover, we cover the whole assemble repair. As a customer, you will also be eligible for free over the phone technical support with our technicians.

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.
