Embodiment approach

[0019] figure 1 It is a block diagram showing an example of the functional configuration of the servo control device according to the embodiment. The servo control device 100 includes a command control unit 10 as a first control unit, and a follow control unit 20 as a second control unit. exist figure 1 Although the example in which the command control unit 10 and the follow-up control unit 20 are connected one-to-one is described in , this embodiment can also be applied to a system in which a plurality of follow-up control units 20 are connected to one command control unit 10 . The tracking control unit 20 is connected to the motor 30 in a one-to-one manner.

[0020] The command control unit 10 generates a position command which is a motor movement command for controlling the motor according to the machining program. The tracking control unit 20 converts the position command sent from the command control unit 10 into a current command, and drives and controls the motor 30 ...

Abstract

Possess: a command control unit (10), which generates advance commands and sequential commands and sends them to the follow-up control unit (20); and a follow-up control unit (20), which, if an external input signal (G) is input, then The motor (30) is driven and controlled based on the advance command stored in the command storage unit (22), and the motor (30) is driven and controlled based on the sequential command stored in the sequential command storage unit (23). Realize the switching from prior command to sequential command during the motor driving process.

Description

technical field [0001] The present invention relates to a servo control device including a command control unit and a follow-up control unit. Background technique [0002] The servo control device includes: a command control unit that generates a motor movement command according to a program; and a follow-up control unit that controls the motor according to the motor movement command. The servo control device starts driving the motor by using an external input signal as a trigger. For example, if the following control unit detects an external input signal, it notifies the detection signal to the command control unit, and based on the notification, the command control unit sends the motor movement command to the follow control unit. Therefore, a delay corresponding to the communication time occurs from the detection of the external input signal by the tracking control unit to the start of driving the motor. [0003] Patent Document 1 shows that by storing the position comman...
