Editing Fault location

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.

|140401|| Position tracing error exceeded the tolerance specified by parameter {{param|FPT}} || Increase {{param|FPT}} 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 {{param|FVT}} || Increase {{param|FVT}} 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 {{param|FEV}} || Increase {{param|FEV}} or avoid running motor too fast
|-
|140404|| Overvoltage. [[HV DC bus]] exceeded the limit defined by {{param|FOV}} || Increase {{param|FOV}} or reduce supply voltage
|-
|140405|| Undervoltage. [[HV DC bus]] was under the limit defined by {{param|FUV}} || Decrease {{param|FUV}} or increase supply voltage and ensure that PSU is capable of supplying demanded current surges without droop

|-
|140801|| Drive has operated over 200 seconds near the overvoltage limit ({{param|FOV}} parameter) which may cause regenerative resistor overheating|| Increase {{param|FOV}} 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

==Abnormal operation fault codes==
Drives are monitoring the internal functionality and the following faults indicate a problem that should not normally occur. These may originate from hardware problem ([[EMI]], supply voltage, bad hardware problem) or can be also a firmware bug.
