Fault location
From Granite Devices Knowledge Wiki
Fault location (a.k.a error codes) ID 1 & 2 that are displayed on Granity Testing tab Device state section. Fault locations are detailed numeric codes giving a hint what was the precise reason causing a fault state. The following table lists fault location numbers and their reasons.
List of Fault location values
| Fault location ID 1 or 2 | Reason | Solution |
|---|---|---|
| 120 | Short circuit protection triggered (very high & fast current rise detected) | Check wiring for shorts, ensure that motor inductance is sufficient (especially ironless & pancake motors), perform Tuning position controller, adjust Over current toleranceFOC. |
| 600 | Overcurrent protection triggered (slower reaction but lower current level than short circuit protection) | Check wiring for shorts, ensure that motor inductance is sufficient (especially ironless & pancake motors), perform Tuning position controller, adjust Over current toleranceFOC. |
| 610 | Current limit parameters Peak current limitMMC and/or Continuous current limitMCC has been set above the supported current range for given Motor typeMT | Reduce current limits to stay within drive's specifications. |
| 3001 | Hall sensors are enabled but no valid signals present (all hall inputs 0's or 1's which is illegal state) | Check wiring and settings |
| 5500 | Motor type Motor typeMT not selected | Choose Motor typeMT |
| 5501 | Unsupported motor type Motor typeMT not selected | Choose Motor typeMT |
| 6601, 6603, 6604, 440501 | Phasing a.k.a. phase search failed | Check motor settings, wiring and supply voltage. Also happens if drive is disabled or hit limit switch during initialization.
The undervoltage fault 440501 means that it was inpossible to induce such current to the load (motor coil) resistance with given supply voltage (Ohm's law). I.e. if motor resistance would be 5 ohms and you have supply voltage of 48V, then theoretical maximum current would be 48/5=9.6A, and in practicel little bit less than that. |
| 6602 | Phasing a.k.a. phase search failed due to both limit switches being open | Check limit switch settings and switch operation |
| 7001 | Selected Limit switch functionLFS is not supported in the selected Control modeCM | Choose another Limit switch functionLFS |
| 480301 | Extracting payload from SMV2 packet failed | Check SMV2 communication |
| 480501 | SMV2 buffer overflow | SMV2 application error |
| 480502 | SMV2 command corrupted because it has overflown payload buffer size | SMV2 application error |
| 480503 | SMV2 return data buffer overflow | SMV2 application error |
| 480601 | Invalid SMV2 command | SMV2 application error |
| 481201, 481202, 481203 | SMV2 communication timeout | SMV2 application error |
| 480801 | Invalid SMV2 SMP packet type | SMV2 application error |
| 480901, 480902 | SMV2 packet CRC error | Communication error |
| 481001 | SMV2 watchdog timeout | Communication error |
| 100201 | Unsupported feedback device selected as position feedback device Feedback deviceFBD | |
| 100202 | Unsupported feedback device selected as velocity feedback device FB2D | |
| 890101 | Resolver feedback device detected loss of input (input signal level less than 0.1V) | Check resolver wiring |
| 140401 | Position tracing error exceeded the tolerance specified by parameter Position tracking error thresholdFPT | Increase Position tracking error thresholdFPT or re-tune motor to achieve lower tracking error, or use lower motion speeds if motor is being driven above the maximum achievable speed or acceleration |
| 140402 | Velocity tracing error exceeded the tolerance specified by parameter Velocity tracking error thresholdFVT | Increase Velocity tracking error thresholdFVT or re-tune motor to achieve lower tracking error, or use lower motion speeds if motor is being driven above the maximum achievable speed or acceleration |
| 140403 | Velocity exceeded the limit defined by Over speed faultFEV | Increase Over speed faultFEV or avoid running motor too fast |
| 140404 | Overvoltage. HV DC bus exceeded the limit defined by Over voltage fault thresholdFOV | Increase Over voltage fault thresholdFOV or reduce supply voltage |
| 140405 | Undervoltage. HV DC bus was under the limit defined by Under voltage fault thresholdFUV | Decrease Under voltage fault thresholdFUV or increase supply voltage and ensure that PSU is capable of supplying demanded current surges without droop. In some drives you may also configure Maximum peak powerMPP to set maximum power that drive is allowed to draw from PSU to avoid this issue. |
| 140406 | Overtemperature | Enhance drive cooling or reduce drive current limits |
| 140407 | STO has been activated, but can be be caused by a drop in logic supply voltage | Provide stable logic supply to drive and to STO inputs |
| 140301 | Limit switch is open while drive is set-up to fault when limit switch is hit | Prevent driving to limit switch or change Limit switch functionLFS parameter |
| 140415 | In pulse/direction setpoint mode, excessive toggle rate detected on direction input pin | Check if HSIN1&2 wiring is correct. Typically occurs when pulse (a.k.a. step) pin is mistakenly wired into direction input. |
| 140801, 801 | Drive has operated significant amount of time near or above the overvoltage limit (Over voltage fault thresholdFOV parameter) which may cause regenerative resistor overheating. Fault occurred to protect indicate the problem and prevent regenerative resistor burn. | Increase Over voltage fault thresholdFOV at least 10% above the average supply voltage or reduce supply voltage. See also Configuring drive voltage limits FUV and FOV. |
| 100201, 100202, 105001, 105201 | Unsupported feedback device has been selected | Choose another feedback device from Granity |
| 101103, 101101, 101102 | Reading device address setting failed | Check address setting resistor values and connection |
| 250101 | Motor initialization failed due to motor has rotated during initialization process (drive has timeouted when waiting motor current to stabilize near zero while motor phases were short circuited to GND by drive) |
For wiring guide, see product wiring manuals. |
| 190601 | Motor initialization failed | Check settings and wirings, and that enable & STO signals stay stable during initialization |
| 440205 | Power stage forced off due to one or more of following reasons: over voltage, over temperature, over current, STO or short circuit active | |
| 440219 | In DC motor mode, parallel wired outputs are not sharing current properly | Check that outputs are wired parallel as instructed |
| 440502 | During Phasing a.k.a. phase search drive could not reach the desired motor winding current even at maximum output voltage (the same voltage that is fed to HV DC bus). | Check that HV supply voltage is not dropping during power on and motor is properly wired to drive. If still occurs, reduce motor peak and/or continuous current limits or increase supply voltage. |
| 441801 | Failed measurement of motor resistance & inductance due to one or multiple reasons: 1) because measurement was unable to reach the desired current level in motor 2) Motor was not standing still during test | If you wish to use the measurement function: try to reduce current limit parameter values MCC & MMC (and click Apply, and then Measure) OR increase HV supply voltage. Also ensure that motor is not being disturbed during the measure (all motor load unmounted). |
| 441802 | Failed measurement of motor resistance & inductance due to result values being off the sanity check limits | If motor has unusually low or high inductance/resistance (below 0.1mH, over 100mH, below 0.1 ohm or above 100 ohm), set them manually instead of using automatic measure |
| 442001 | Actual torque exceeded target torque indicating that torque controller might have became unstable. | Check parameters MR and ML which may cause instability or overshooting of torque. If unsure whether they are correct, see Tuning torque controller. If no help, then increase Over current toleranceFOC. Ultimately try setting FOC to Maximum. |
