Abstract Beam commissioning of SuperKEKB Phase-I started in Feb., 2016. In order to protect the hardware components of the accelerator against unstable Ampere class beams, the controlled beam abort system was upgraded. Because of the higher beam intensity and shorter beam lifetime than at the original KEKB, a beam abort monitor system is important for machine tuning and the safety of the components. The system collected the data of all aborts of more than 1000 in this operation period, and we diagnosed not only the hardware performance but the tuning software by analyzing the relations between beam current, loss monitor signals and RF cavity voltages. This paper will give the outline of the monitoring system, and will present typical examples of signal and diagnoses.
