The use of PLC positioning instruction program and servo wiring diagram

Here we use the mitsubishi FX - 3 u PLC controller and panasonic A5 servo drive, we designed a stop on the PLC instruction, far point regression, anomalistic signals, the interrupt signal, as well as the positive &negative limit and so on.

servo drive parameter Settings:

Pr0. 01 = 0; Position control mode,

Pr0. 00 = 1; Set motor direction of rotation, the Pr0. 05 = 0; Photoelectric coupling input, Servo drive there are two ways to enter: one kind is input, photoelectric coupling is a kind of differential input. )

Pr0。 6 = 0; Command pulse polarity Settings, Pr0. 7 = 3; Pulse + direction input mode,

Pr0. 08 = 3000; Motor command pulse number every turn 1 weeks,

Pr4. 6 = 3847 ( 00000F07H) ; Set the S17 to reset input,

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

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

Pr4. 01 = 65793 ( 00010101 h) ; Set the SI2 to forward limit 2 switch input.

Pr5。 4 = 0; 2 effective positive &negative limit switch,

Pr5. 05 = 2; Positive &negative set limit order, the counter to zero and eliminate pulse deviation

input and output signal description:

low X0 stop positioning instruction execution,

low X1 - Through to switch moment, can perform the origin return instructions ( DSZR)

low X2 origin, near point signal input,

low X7 origin return, receive the encoder Z believe number input terminal of the servo driver output. The signal is zero.

●Y000 - Pulse output,

low Y003 - - - - - - - Motor rotation direction signal output end

low Y005 - Reset signal output terminal.

description:

1, using X001 input start DSZR origin return instructions

2, using the M22 is turning point, perform DRVI relative positioning instructions.

3 USES M23 reversal points, perform DRVI relative positioning instructions.

4, use m2-m24 forward start, perform DRVA absolute positioning instructions.

5 start use the M25 reversals, perform DRVA absolute positioning instructions.

6 USES M31 start, perform ZRN origin return instructions.

7 use start M32, executing DVIT concluded that instruction.
