Help with wiring

[AM Machine]

Recently we purchased the following from Keling but are unable to get it to work due to our inexperience. We get a green light on the 8078 until we try to make the motor move then a red fault light. The motor is also making a high pitched noise when green light is on. John has been helpful but our inexperience is where we are lacking

C10 Breakout board with 5V power supply
8078 driver
7220 power supply
Nema 42 (KL42H)

This is how we have it setup. We have tried a number of setup but this is how it is currently. We are just using a simple LPT program to activate and de-activate the pins on the parallel cable to get it to step.

The KL 7220 is providing 70V to the 8078
The KL-10-5 is providing 5V to the C10 board

Motor is wired bipolar (series) according to the PDF on the website
Motor blue wire to A+ on 8078
Motor green wire to A- on 8078
Motor brown wire to B+ on 8078
Motor white wire to B- on 8078
Motor orange tied to motor black
Motor red tied to motor yellow

C10 Pin 8 to Dir - on 8078
C10 Pin 9 to Pul - on 8078

Dir + on 8078 to 5V on C10
Pul + on 8078 to 5V on C10

C10 In/Out jumper set to [1-2] Output
C10 Com jumper set to [2-3] 5V
C10 2-9 pin jumper set to [2-3] Pull up

Dip switches on 8078 set to 400 steps per rev and 2.8A according to diagram
on top of 8078

Thanks for any advice.

Also, when trying to use the motor tuning section of Mach 3, we get one step before the fault light on the 8078 is activated. Thanks

Do you have the +5 volts connected to the enable pin and the 5volt pin on the C10?

Do you have the estop connection on the C10 jumpered?


See attached image.

Yes. Thank you for the diagram though.

We are officially giving up on this and it appears we are going to order new Parker Hannafin motors and controllers. They cost about $3000 more but are plug and play pretty much. That helps us simple minded people.

Jeff,

Many thousands of the Keling "Leadshine" drivers are running machines world wide, you may have received a defective unit.

Ask John to ship a replacement before you give up.

Hi Jeff

It is very close. You set up the Mach3 properly, it will work

Thanks for all the help and phone support John but we are just unable to get it figured out. Even if when we had the parallel cable unplugged from the board the 8078 would give a fault light as soon as it was plugged in when wired in bipolar parallel. We were doing something wrong but wouldnt figure out what it was that we were doing wrong. At one time there were 5 of us working on it and no one had a clue. lol

Jeff,

Did you leave ENA+(+5V) disconnected on the 8078?

Jeff...

We tried both ways.

We pulled out an old Parker compumotor plus (NEMA 56) and hooked it up to the Keling C10 breakout board and are controlling it with Mach 3. It's up and running and now we just have to make and adapter plate to mount it on our timing screw machine and we should be good to go. We'll just have to make some changes to the original software that we wrote so that it will work with this new motor.

Once we get caught up, we are going to see if we can figure out what errors we made with the 8078 and NEMA 42 motor.

Jeff,

It sounds like the 8078 may be defective.

Please keep us posted on your progress.

Thanks John. We'll definitely make another go at it.
