I looked at the drawing you posted and I am confused as to exactly how you have Output 1 and Output 2 wired:
Brake release.JPG
Your outputs as you have them assigned:
;------------------------------------------------------------------------------
; Output Definitions
; Logic 1 = OUTPUT ON (Green), 0 = OUTPUT OFF (Red)
;------------------------------------------------------------------------------

; DO NOT MODIFY
; #wizardregion Outputs
NoFaultOut IS OUT1
Axis3BrakeRelease IS OUT2
SpinFWD IS OUT3
SpinREV IS OUT4
DriveResetOut IS OUT5
OUTPUT6 IS OUT6
Mist IS OUT7
VacuumOn IS OUT8
; #endregion

Yes, I can..the 3rd axis I referring to my 2nd problem, not Z-Axis

"- if I manual jog, I can move x and y no problem, soon I hit Z, "Drive fault". so I reset, then I tried Z and Y manual jog, its work fine, but soon I hit X, "Drive fault" again. Then I hit reset, again I tried X and Z, work fine, soon I hit Y, "Drive fail".
seem like I cant manual Jog 3 axis. the 3rd one always "Drive Fault". do you know what causing I cant jog the 3rd axis?"

sorry if I created confusion.

On the drawing , Output2 connected to SSR to activate the brake.
I have Power4-hub, Output1 is connected to SSR that control 75V servo power.
so soon I hit the E-brake, the power feeding the servo is cut off.

The key here is to have the servo enable and the brake work in-sync. What about finding a way to have the relay that handles the Drive_OK signal to also handle the servo brake? Maybe using that relay to drive other relays?

Hi Art..
the brake and servo are in sync, because I can jog manually without any problem.

If I understand this right, all is well -- that is, no drives are in a fault condition, the brake releases if/when needed, and the axes move under control -- as long as only one or two axes are enabled. As soon as all three axes are enabled, he gets a drive fault condition.

I don't think there is anything wrong with the brake circuit. I think he needs to take a hard look at the enable circuit(s) and the fault circuit(s).

Could it be that the system tries to move the motos as soon as it activates and before the system is fully active? What about adding a G4 at the top of the gcode?

How are you activating the C86 board? Axis Enable? No_Fault?

Axis enable - Jumper
No Fault to Input5
what do you mean activating? before I can start to manual jog, I have to click the reset button on VCP

I noticed pop up message after I clicked "Cycle Start" that disappeared within 1 sec, and i manage to do screen shoot.
