Cause : Speed match comes when motor speed has exceeded the steady state deviation level (par. 74.2) or the ramping state deviation level (par. 74.3), and the delay defined with parameter 74.4 Speed match fault delay has elapsed.

D105 warning in ABB ACS880 drive indicate that motor speed has exceeded the steady state deviation level or the ramping state deviation level

1. Check the torque and current limit settings.
2. If an encoder is used, check the encoder settings.
