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

| 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 |
| 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 |
| 140801 | Drive has operated over 200 seconds near the overvoltage limit (Over voltage fault thresholdFOV parameter) which may cause regenerative resistor overheating | Increase Over voltage fault thresholdFOV at least 10% above the average supply voltage or reduce supply voltage |
| 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 it to stop) | Ensure that motor is standing still before initialization starts |
| 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 |
