Teknic Eclipse servo wiring (Solved)

[Ken Rychlik]

I am starting on a axyz retrofit that has a mix of servo's and steppers. They used servo's for x and y. The Z and Atc rotary have steppers.
I have a pdf of a similar driver of the same series, but the part number is specific to axyz through teknic. The stepper drivers, I have used before and they are not an issue.

The tool rack is interesting in that it uses an air cylinder to push the tool up into the spindle. I need to hardware pair the two x drivers on this one but need to reverse one motor. It sends out 3 phase to the motor, so I am thinking switch two wires like you do on a spindle to change direction. I have not tried this, but it seems logical.

I am attaching a few pics and the pdf of the driver series. It looks like 5v logic for the most part. Page 15 of the pdf shows the DB25 step/dir but it looks like a solid ground and positive pulses are needed.

Working wire pin outs on the drivers: I used Leadshine DM for now as they use similar 5v logic.
pin 4 enable (Apply gd to enable)
Pin 5 Alarm (applies gd when ok, breaks circuit when tripped)
pin 6 step
pin 7 gd for step/dir
pin 8 dir
pin 17 and 18 (limit + and - need ground for movement
pin 20 needs 5v applied for the logic
pin 21 logic ground

UPDATE they function on the acorn db25 step and dir with pin7 from the Driver db25 to ground on the acorn db25

So having a DB25 on the acorn AND a DB25 on the servo drive makes it interesting

Thanks

Page 19 of the Teknic user manual states that the Step, Direction, and Enable signals can be either TTL (5VDC) or open-collector.

SSt-Eclipse drives can support any stepper motor indexer or pulse source
that produces industry-standard step and direction signals. The step and
direction signals from the indexer should be open collector or TTL-level
driven signals. Shielded wiring should be used for these signals (shielded,
twisted pair wiring is preferred for the Step input).

Appendix A shows that the drive uses 5VDC for J1, which is the connector to control step/direction/enable.

Yup, they are 5V and you can wire them to the DB25. You can also wire the newer Clearpath servos the the DB25 with 5V.

Thanks guys, I have movement and updated the wiring pins in the first post.

My issue now is I need to reverse one motor that is to be hardware paired to another. I tried switching two of the R S T motor phase wires and got no movement at all. I put them back and it still works, but I still have the reversing problem.

I decided to try the other driver for the Y and it had been reversed in the Teknic Drive, so just switching drivers around solved that issue.

Next is figuring out the emerson vfd drive.

Thanks
