The menu thathas been changed can be identified by the sub-trip number.If more than one menu has changed the lowest menu has priority. Drive user parameters must be saved to prevent this tripon the next power-up.Recommended actions:• Reset the trip and perform a parameter save to accept the new settingsAutotune 1 Position feedback did not change or required speed could not be reached11The drive has tripped during an autotune. The cause of the trip can be identified from the sub-trip number.Recommended actions:• Ensure the motor is free to turn i.e. mechanical brake was released• Ensure Pr 03.026 and Pr 03.038 are set correctly (or appropriate 2nd motor map parameters)• Check feedback device wiring is correct• Check encoder mechanical coupling to the motorAutotune 2 Position feedback direction incorrect12The drive has tripped during a rotating autotune. The cause of the trip can be identified from the associated sub-tripnumber.Recommended actions:• Check motor cable wiring is correct• Check feedback device wiring is correct• Swap any two motor phasesSub-trip Reason1 Menu 182 Menu 193 Menu 20Sub-trip Reason Recommended actions1The position feedback did not change whenposition feedback is being used during rotatingauto-tune.Ensure that the motor is free to turn (i.e. mechanicalbrake is released).Check that the position feedback is selected correctlyand operates correctly.2 The motor did not reach the required speedduring mechanical load measurement.Ensure that the motor is free to turn and that the staticload plus inertia is not too large for the drive to acceleratewithin the test time.3The required commutation signal edge could notbe found during a rotating auto-tune with aCommutation Only position feedback device.Check that the position feedback signals are connectedcorrectly.4 The required movement angle cannot beproduced during a minimal movement test. Reduce the angular movement required.5The second part of the minimal movement testduring auto-tuning cannot locate the motor fluxposition accurately.Reduce the angular movement required.6The phasing offset angle is measured twiceduring a stationary auto-tune and the results arenot within 30 o of each other.If a minimal movement test is being used and excessivemotor movement is occurring during the test reduce therequired angle movement. Otherwise try and increasethe required angle movement.7The motor is moving when a phasing test onenable is selected and the drive is enabled, butthe motor is still moving at a speed above thezero speed threshold.Ensure that the motor is stationary before the drive isenabled.8 An auto-tune has been attempted while the AMCis selected. Set AMC Select (31.001) to zero to deselect the AMC.Sub-trip Reason1 The position feedback direction is incorrect when position feedback is being used during a rotatingautotune2 A SINCOS encoder with comms is being used for position feedback and the comms position is rotatingin the opposite direction to the sine wave based position..
