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

| 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. |

| 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 |

| 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. |

| 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. |

| 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. |
