Mitsubishi plcfx3u and servo drive wiring tutorial

Here we use Mitsubishi FX-3U PLC and Panasonic A5 servo drive. We design stop command, far point return, near point signal, interrupt signal, forward and reverse limit etc. on PLC. Because we have introduced similar wiring diagrams to you before, we will not introduce them one by one now.

Servo drive parameter settings:

Pr0.01=0; Position control mode,

Pr0.00=1; motor rotation direction setting, Pr0.05=0; photoelectric coupling input, (the servo drive has two input modes: one is photoelectric coupling input, the other is differential input.)

Pr0.06=0; command pulse polarity setting, Pr0.07=3; pulse + direction input mode,

Pr0.08=3000; the number of command pulses per motor revolution,

Pr4.06=3847 (00000F07H); Set S17 as the reset input terminal,

Pr4.11=131586 (0002020202H); Set S02 as the servo ready output terminal,

Pr4.00=131586 (0002020202H); Set I1 as the reverse limit 2 switch input terminal,

Pr4.01=65793 (00010101H); Set SI2 as the forward limit 2 switch input terminal.

Pr5.04=0; forward and reverse limit switch 2 is valid,

Pr5.05=2; forward and reverse limit sequence setting, and clear the pulse deviation counter to zero

Input and output signal description:

●X0-Stop Positioning instruction execution,

● X1- switch is turned on instantly, and the origin return command (DSZR) can be executed

● When X2 returns to the origin, the near point signal input terminal,

●X7--When returning to the origin, it receives the encoder Z-phase signal input terminal output by the servo driver, that is, the zero point signal.

●Y000 - pulse output terminal,

●Y003- - Motor rotation direction signal output terminal

●Y005- Clear signal output terminal.

illustrate:

1. Use the X001 input terminal to start the DSZR origin return instruction

2. Use M22 forward jog to execute the DRVI relative positioning instruction.

3 Use M23 to reverse jog and execute the DRVI relative positioning instruction.

4. Use M24 to start forward and execute the DRVA absolute positioning instruction.

5 Use M25 to start reverse and execute DRVA absolute positioning instruction.

6 Use M31 to start and execute the ZRN origin return instruction.

7 Use M32 to start and execute the DVIT interrupt fixed-length instruction.
