摘要： A component mounting machine includes a head having at least one set of multiple pickup members arranged so as to be liftable and lowerable, a moving device for moving the head, at least one feeder, and a control device. The feeder is configured to receive correction values for the number of sets of the multiple pickup members, set a target feeding amount for the number of sets based on the received correction values for the number of sets, and sequentially feed components for the number of sets in a predetermined direction with each set target feeding amount. The control device is configured to acquire a positional deviation amount of the multiple pickup members in the predetermined direction for each set, and transmit the correction values for the number of sets based on the acquired positional deviation amount for the number of sets to the feeder so that the feeder collectively receives the correction values for the number of sets at a predetermined timing.

摘要： The motor control device is capable of driving control of the stepping motor with a pre-excitation that excites the stepping motor for a first time with a current lower than that during driving before starting or when starting driving the stepping motor, and a post-excitation that excites the stepping motor at a current lower than that during driving when stopping or after stopping the driving of the stepping motor for a second time, and is capable of continuing the post-excitation and the pre-excitation for a period of time shorter than the sum of the first time and the second time when the post-excitation at the previous stopping of driving of the stepping motor and the pre-excitation at the next starting of driving of the stepping motor are executed without passing through the non-excited state.
