Cause : Position feedback direction incorrect comes when the drive has tripped during a rotating autotune. The cause of the trip can be identified from the associated sub-trip number.

Sub-trip & Reason

1 The position feedback direction is incorrect when position feedback is being used during a rotating autotune
2 A SINCOS encoder with comms is being used for position feedback and the comms position is rotating in the opposite direction to the sine wave based position.
