  • Patent number: 11809148
    Abstract: A feedback gain and a speed feed-forward gain are adjusted. A method for adjusting control parameters for a control device that performs servo control on a control target includes calculating an upper limit of a feedback gain of a feedback signal within a range in which a predetermined index for the feedback gain satisfies a predetermined target value with a speed feed-forward gain for speed feed-forward control set at a predetermined reference value, setting the feedback gain at an adjustment initial value lower than the upper limit, setting the speed feed-forward gain at the highest value within a settable range, and increasing the feedback gain from the adjustment initial value within a range in which the feedback gain does not exceed the upper limit with at least the speed feed-forward gain set at a predetermined increased value.
    Type: Grant

  • Patent number: 10884962
    Abstract: A main control section (30) of a slave device (3) include a slave controller (31), a processor (32), and a watchdog circuit (33) which are configured as a one-chip integrated circuit. In a case where the watchdog circuit (33) has detected that a malfunction has occurred in an operation of the main control section (30), the watchdog circuit (33) resets the processor (32) while not stopping an operation of the slave controller (31).
