Abstract
A controller capable of transmitting and receiving an input signal from a drive circuit corresponding to a moving device, a mounting head, or the like of an electronic component mounting machine or an output signal to the drive circuit for each predetermined period (A/2), in which the controller computes an output signal based on an input signal which is received before the predetermined period, stores the output signal for a time greater than or equal to the predetermined period, and subsequently transmits the output signal to the drive circuit. It becomes possible to set a time (a delay time) from when an input signal is output until an output signal reaches a drive circuit to an arbitrary length by adjusting the storage time.
Claims4
1:
- A servo controller capable of transmitting and receiving an input signal from a drive circuit corresponding to an actuator device of a manufacturing work machine or an output signal to the drive circuit for each predetermined period,
- wherein the servo controller computes an output signal based on an input signal which is received before the predetermined period, stores the output signal for a time greater than or equal to the predetermined period, and subsequently transmits the output signal to the drive circuit.
2:
- The servo controller according to claim 1,
- wherein a second servo controller capable of transmitting and receiving an input signal from the drive circuit or an output signal to the drive circuit for each second period which is longer than the predetermined period computes an output signal based on an input signal which is received within the second period, stores the output signal for a shorter time than the second period or does not store the output signal, and subsequently transmits the output signal to the drive circuit, and
- wherein a time from a timing at which the drive circuit transmits an input signal to the servo controller until a timing at which the drive circuit receives an output signal from the servo controller is the same as a time from a timing at which the drive circuit transmits an input signal to the second servo controller until a timing at which the drive circuit receives an output signal from the second servo controller.
3:
- The servo controller according to claim 1,
- wherein the servo controller is capable of transmitting and receiving an input signal from a second drive circuit corresponding to a second actuator device which is different from the actuator device of the manufacturing work machine or an output signal to the second drive circuit for each predetermined period, and the servo controller computes an output signal based on an input signal which is received within the predetermined period, stores the output signal for a shorter time than the predetermined period or does not store the output signal, and subsequently transmits the output signal to the second drive circuit.
4:
- The servo controller according to claim 3,
- wherein the actuator device is a work head, and
- wherein the second actuator device is a moving device for moving the work head to an arbitrary position.
