摘要： The present disclosure is intended to enable a user to grasp a state of load on an arithmetic processing unit (100, 200) so that the user can stop an excessive function of the arithmetic processing unit (100, 200), or can transfer part of arithmetic processes to another arithmetic processing unit (100, 200) with a small load. Included are the arithmetic processing unit (100, 200) that executes a plurality of processes related to servo control processing; and an observation unit (300) that determines at least one of point-of-time information about start of each of the processes executed by the arithmetic processing unit or point-of-time information about end of each of the processes executed by the arithmetic processing unit; and an output unit (400) that calculates information about usage of the arithmetic processing unit based on the point-of-time information determined by the observation unit, and outputs the calculated information. The information about the usage is constituted by, for example, a processing time period during which the processes are executed by the arithmetic processing unit, a difference between a given processing time period and the processing time period during which the processes are executed, a ratio of the processing time period during which the processes are executed to the given processing time period, or a ratio of the difference to the given processing time period.
