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.

==List of Fault location values==

{| class="wikitable sortable"
|-
! 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 {{param|FOC}}.
|-

| 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 {{param|FOC}}.
|-
| 610 || Current limit parameters {{param|MMC}} and/or {{param|MCC}} has been set above the supported current range for given {{param|MT}} || 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 {{param|MT}} not selected || Choose {{param|MT}}
|-
| 5501 || Unsupported motor type {{param|MT}} not selected || Choose {{param|MT}}
|-
| 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. 
*6601 is caused by "Run" status becoming false in the middle of phasing. 
*6603, 6604, and 440501 means that supply voltage was not high enough to drive motor peak current {{param|MMC}} to motor coils (check [[HV DC bus]] supply and motor connection or try lower MMC value).
The undervoltage fault 440501 means that it was inpossible to induce such current to the load (motor coil) resistance with given supply voltage (I=U/R a.k.a. 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 practice little bit less than that. In such case any MMC parameter value near or above 9.6A would cause this fault.
|-
| 6602 || [[Phasing a.k.a. phase search]] failed due to both limit switches being open || Check limit switch settings and switch operation
|-
| 7001 || Selected {{param|LFS}} is not supported in the selected {{param|CM}} || Choose another {{param|LFS}}
|-
| 480301|| Extracting payload from SMV2 packet failed || Check SMV2 communication
|-
| 480401, 480402, 480403, 480404 || Inserting requested return data packet into outbound SM packet caused overflow (requested return value did not fit in the 120 byte payload). 

Fault location number depends on the size of return data value which caused the overflow: 480401 for SMPRET_32B value type, 480402 for SMPRET_24B value type, 480403 for SMPRET_16B value type, 480404 for SMPRET_CMD_STATUS type. 
|| SMV2 application error as it has requested larger amount of return data that fits in payload buffer. If you have written low level SM communications, check your payload management. If you used higher level SM library commands, please report us which function has caused this and how to reproduce the issue.

|-
|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

|-
|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 ({{param|FOV}} parameter) which may cause regenerative resistor overheating.

|This fault location never appears on standard firmware releases. Try a standard firmware if possible, or ensure that motor settings are the ones that are listed as supported for the custom firmware.
|-
|250101 || Drive initialization has timeouted while waiting motor current sensor signals to stabilize (while motor phases were short circuited to GND by drive). Possible reasons:
* Motor initialization failed due to motor has rotated during initialization process 
* Electrical noise is disturbing current sense circuit of drive
||
* Ensure that motor is standing still before initialization starts
* Ensure proper cabling (shielded cable on motor and connected to drive)
* If necessary, add ferrite core filter on motor phases
* Try if error is affected by disconnecting external devices, such as encoder cable
For wiring guide, see product wiring manuals.

Also ensure that motor is not being disturbed during the measure (all motor load unmounted).
|-
