Hello all,
I have changed from steppers to clearpath servos. All went well in the conversion and my machine is running great.
I do have a question regarding the correct setup of the drive ok input. I am using the C86ACCP. It is all setup an configured mostly from watching one of Marty's videos on it.
It seems that the drive ok input should be configured as NC green circle, however when I configure it that way I get the drive fault once I move any axis. If I have it configured as NO red circle it works but I can't seem to produce a drive fault like on purpose to trip the drive OK input to test it.
Maybe I am missing something.
He says,
OK...Here is the scoop:
1 Ignore the schematics DO NOT SET ANY INPUT TO DriveOk at this time DO THIS LAST!!!
2 Put a wire jumper across the 2 terminals next to the power input terminals (new ones come this way)
3 Power the 86accp from the Acorn4 +24VDC& COM terminals, so it is on when the acorn is on
4 Set the Acorn Enable Jumper (next to the red power LED) to OFF
5 Make sure the Hard/Soft jumpers are all set to HARD
6 Set the ACTIVE AXIS jumpers for the X, Y and Z to ON (terms 2 & 3)
Are you using Independent auto square? Are you sure that you need it? If so GOTO #8
7 If you are pairing an axis (no autoquare) set all 4 of the SLAVE jumpers to 1-2 for X and 2-3 for Y. ALL 4!!!
If not using autosquare, install the C86 board into the terminals making sure that you are in all 16 terminals securely
GOTO #10
8 Set the ACTIVE AXIS (4th) mislabeled as "A" to on
9 Remove the 4 slave jumpers and set aside
Install the C86 board into the terminals making sure that you are in all 16 terminals securely
10 Place short wire jumpers connecting the 2 position terminals marked ALAR & GND together for each axis you will be connecting to 11 Connect 24vCOM to relay terminal V IN and Connect a wire from the NC terminal to the input you will use for DriveOk NC
Connect any ONE axis you wish to test or tune to its terminals or plug. If using terminals, Ignore the RED/GRN HLFB wires for now.
move and autotune that axis. Repeat, one at a time for the rest of the motors.
All done? All axes moving? Remove the short jumpers, install the red/grn wires and set the input connected to in step #11 to Drive OK
Here is what is confusing, everything that I have read and all diagrams say to use the NO contacts on this relay that is referenced in step 11.
Is this correct? or a typo.
So back to this. I wired everything according to diagram S15072r4.pdf
In looking at different videos and pictures I see that input 5 set as drive ok is green when enabled. I currently have input 5 for drive ok and set as normally open. If I set it to normally closed like everything I read and see I get a drive fault once I start jogging any axis. The issue is if I do create a drive fault on purpose that does not get relayed to input 5 and produce a shutdown. If fact I have never seen input 5 lite up green no matter what combination I try. When input 5 is set to Normally open everything operates fine but then I don't have any protection in case of a fault.
So am I missing something? Not sure where to go from here.
Thank you
Bill
Ok, so the problem was kind of a dumb error on my part. I was using the wrong common for the feed to input 5. Since I use a separate 24v power supply for inputs I just needed to move it over to that power supply.

For Guys that wish to use the C86ACCP interface board, here is a doc that simplifies the installation and allows you to test/bench test a single motor, etc.
