Parameter 0 = Position control mode. Parameter 21 = 0001 signed pulse train, positive logic. Inportant are basic parameters from 0 - 7. And there are more parameters to set. Wiring in attachment. AttachmentMR-J2S.pdf (896 Downloads) |

Now wiring is done as in the attachment. This is open collecter (200kpps) type connection. What you have attached is differential receiver(500kpps) type connection. Now situation is that cpu is feeding pulses and direction changes from cpu side also fine. But servo drive is not taking it. AttachmentWiring.pdf (859 Downloads) |

I do not know how you connected PLC outputs exactly (contacts PG and NG are not shown). Use my wiring if you use 1200 DC PLC. This PLC outputs are sourcing type (and only sourcing!) not open collector. You should understand how current flows from output to servoamp input (also inside amplifier). Also not connect VDD (CN1B pin 3) and COM (CN1B pin 13). Connect COM to the 3M ( 0 VDC) of controller. Look at page 3-10 in thismanual. I hope that is correct manual. I hope you understand my explanation. See attached picture. If i am wrong, correct somebody. |

None of them are differential, your wiring uses a high speed board ( we don't know what is it), but you can't speed up anything with it. The proposed wiring from kriipcis ok, better than yours, except there is no mention of voltages, if servo has 5V input you can use signal board 5V or add resistors. With 24V don't expect high speeds, not more than 20khz. You have also to find out if your drive is configured to accept step/dir pulses, not quadrature, as well also other signals SON, ... |
