SERVO CONTROL DEVICE, SERVO CONTROL SYSTEM AND SERVO CONTROL METHOD

摘要

The present invention enables a user to recognize a load state on an arithmetic processing unit (100, 200), so that the user can stop an excessive operation of the arithmetic processing unit (100, 200) or a part of the arithmetic processes to another arithmetic processing unit (100 , 200) can transmit with a small load. Included are: the arithmetic processing unit (100, 200) that performs a variety of processes related to servo control processing; an observation unit that determines timing information at the start of each of the processes executed by the arithmetic processing unit and / or timing information at the end of each of the processes executed by the arithmetic processing unit; and an output unit that calculates information on the use of the arithmetic processing unit based on the time information determined by the observation unit and outputs the calculated information. The information on the usage is represented 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 are formed at the given processing time period, or a ratio of the difference to the given processing time period.
