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

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.

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	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
