- the programmable controller targeted by the present invention is configured to output a pulse train signal, which is a position command pulse, to the motor driver for control.
- This position command pulse is generated by the following procedure. That is, the programmable controller calculates and generates a positioning pattern of a motor driven by a motor driver based on positioning setting data including a target position and a target speed in positioning control using a start command as a trigger. It is converted into a position command pulse in one pulse output mode among the three pulse output modes (A phase / B phase, CW / CCW, PULSE / SIGN) and output.
- the start command may be output during the execution of the ladder program or may be input from the outside.
- the motor driver is configured to perform motor control in response to a rising edge and a falling edge in each cycle of the position command pulse, but the first half in each cycle of the position command pulse output by the conventional programmable controller.

- the program memory 5 generally stores a control program (ladder program) in which positioning control is described, and setting data including a target position and target speed in positioning control.
- control program ladder program
- initial phase information of the position command pulse output to the motor driver 2 is further stored. Since this initial phase information is used by the position command pulse generating means 8 as will be described later, it may be set in advance in the positioning control unit 4 so that the position command pulse generating means 8 can retrieve it.
- the sequence execution means 6 reads the ladder program from the program memory 5 and executes it.
- the start command a is output to the positioning pattern generation means 7 and the positioning setting data b read from the program memory 5 according to the position control sequence is output to the positioning pattern generation means 7.
- the positioning setting data b includes initial phase information of the position command pulse.
- the positioning pattern generation means 7 may receive a start command c from the outside. In this case, the positioning pattern generation unit 7 selects either the start command a from the sequence execution unit 6 or the external start command c. The positioning pattern generation unit 7 generates and calculates a positioning pattern of the motor 9 driven by the motor driver 2 based on the positioning setting data b input from the sequence execution unit 6 with the start command a or the external start command c as a trigger. And the generated positioning pattern d is output to the position command pulse generation means 8.
- the positioning pattern d includes the initial phase information of the position command pulse extracted from the positioning setting data b.
- the position command pulse generation means 8 generally generates a position command pulse in a pulse output mode that matches the specifications of the motor driver 2 from the positioning pattern generated by the positioning pattern generation means 7 and outputs it to the motor driver 2.
- the pulse output mode includes an A phase / B phase mode (90-degree phase difference pulse method), a CW / CCW mode (two pulse method), and a PULSE / SIGN mode (common pulse method).
- the position command pulse generation means 8 outputs position command pulses “A phase pulse train signal Pa, B phase pulse train signal Pb” in the A phase / B phase mode.
- the motor driver 2 performs motor control in response to rising edges and falling edges of the A-phase / B-phase pulse train signals Pa and Pb.
- the motor 9 driven by the motor driver 2 is a servo motor or a stepping motor disposed on each axis of a positioning device used for processing / assembly or component mounting in the production process.
- the position command pulse generating means 8 applies the positioning pattern from the positioning pattern generating means 7 and the initial phase information of the position command pulse included in the conventional circuit configuration, A phase / B phase pulse train signals Pa and Pb are generated with the initial phase advanced from the previous phase “0 °” by the phase “arbitrary phase in the range of 0 ° to 180 °” indicated by the initial phase information. (See, for example, FIGS. 2 and 3).
- FIGS. 2 and 3 are timing charts for explaining an example of the operation for advancing the initial phase of the position command pulse.
- FIG. 2 shows the operation when the cycle of the head pulse of the position command pulse is short, and FIG. Shows the operation until acceleration time is long).
- 2 and 3 show the operation when the pulse output mode is the A phase / B phase mode, but the same applies when the pulse output mode is the CW / CCW mode or the PULSE / SIGN mode.
- 2 (1) and 3 (1) show the case where the initial phase is advanced by 0 ° in the A phase / B phase mode, that is, the previous operation.

It is assumed that the signal is output with a phase relationship delayed by 90 ° from the signal Pa.
- the initial state of the signal lines of the A-phase / B-phase pulse train signals Pa and Pb until the position command pulse generation means 8 starts to output pulses is at a low level in this embodiment. That is, this initial state may be at a high level.
- the position command pulse generation means 8 When the initial phase indicated by the initial phase information of the position command pulse set in the program memory 5 is 0 °, the position command pulse generation means 8 generates the A-phase / B-phase pulse train signals Pa and Pb as before. To do. That is, each period of the conventional A-phase / B-phase pulse train signals Pa and Pb has the same low level in the first half cycle and the high level in the second half cycle. Then, the leading pulse of the leading A-phase pulse train signal Pa first input to the motor driver 2 continues at the same low level as the initial state in the first half cycle and then rises to the high level. For one cycle of the first pulse of the pulse train signal Pa, the motor control is started at the change timing from the first half cycle to the second half cycle, and the start of the motor control is awaited during the period of the first half cycle.
- the conventional positioning control start time T1 is a time obtained by adding the output pulse waiting time 12 to the trajectory generation time 11.
- the trajectory generation time 11 is a time period until the positioning pattern is calculated and generated using the start command as a trigger and the A-phase pulse train signal Pa is output.
- the output pulse waiting time 12 is the time of the first half period of one period 13 of the first pulse of the A-phase pulse train signal Pa.
- the conventional positioning control start time T3 is a time obtained by adding the output pulse waiting time 14 to the trajectory generation time 11, but one period 15 of the first pulse of the A-phase pulse train signal Pa. 2 is longer than in the case of FIG. 2, the output pulse waiting time 14 is longer than the output pulse waiting time 12, and the starting time T3 is longer than the starting time T1.
- the position command pulse generator 8 when the initial phase indicated by the initial phase information of the position command pulse set in the program memory 5 is, for example, 180 °, the position command pulse generator 8 generates the initial values of the A / B phase pulse train signals Pa and Pb.
- the phase is generated 180 degrees ahead of the previous level. In this case, this corresponds to the fact that the previous A-phase / B-phase pulse train signals Pa and Pb are generated in a logically inverted form. Therefore, when the position command pulse generation means 8 starts pulse output, As shown in FIGS. 2 (2) and 3 (2), the leading pulse of the A-phase pulse train signal Pa rises from the initial low level to the high level at the end of the trajectory generation time 11, and starts the first half period. After elapses, the waveform falls to a low level and starts the second half cycle.
- the motor driver 2 can start motor control at the start timing of the first half cycle of the first pulse of the leading A-phase pulse train signal Pa.
- the control start time T2 is the same as the trajectory generation time 11 without the output pulse waiting times 12 and 14 shown in FIGS. 2 (1) and 3 (1).

- the same period 15 is used in the case.
- the time width of the output pulse waiting times 12 and 14 when the initial phase shown in FIGS. 2 (1) and 3 (1) is 0 ° is the initial phase adjustment width, and the initial phase of the position command pulse. Can be adjusted to an arbitrary phase within a range from 0 ° to a maximum of 180 °.
- an arbitrary initial phase within the range of 0 ° to 180 ° is stored in the program memory without changing the basic architecture of the hardware and software of the programmable controller.
