CONTROL UNIT 12H INT VENT A06B-6055-H112#H538

When your FANUC 12H INT VENT Control Unit needs service, there are any number of repair centers where you can send it. Only one offers technical expertise, fast service, incredible value and an unrelenting commitment to excellence: Tri Star CNC Services.

Unlike many repair centers, we don't outsource the work to overseas contractors. All work is done in-house at our Illinois facility by experienced technicians with a combined 90+ years of experience working on GE FANUC and FANUC equipment.

We treat every job as a priority. We'll give your A06B-6055-H112#H538 Control Unit a thorough diagnosis and cleaning, replace any small electrical components known to have a high failure rate, and make all necessary repairs using OEM or better quality parts. We can even custom engineer replacement parts if none are available - usually at lower cost than the original part.

Before sending your unit back to you, we test it on a closed loop system to ensure it performs to original manufacturer specifications. And all our work is backed by an incomparable one-year parts and labor warranty on the entire assembly repair.

Our commitment to providing honest, affordable and expert repair services on CNC equipment has earned us a reputation as THE alternate source for FANUC and GE FANUC repairs and replacement stock. Try us once and you'll see why.

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.
