Boss Spindle Brake

[Aplus]

I'd like to add a 5 sec delay when the spindle brake comes on after an M5 or spindle stop (red Stop Button on VCP). I have a VFD set to brake to a stop in 5 Sec however the brake comes on as soon as the stop command is sent to PLC. This doesn't sound good and my grey hairs are telling me something (Brake or Motor or Both) isn't going to last long. I have read the PLC programming manual but am still lost. I believe the code will go here along with a timer definition.
;----------------------------------------------------------------
; Auto Spindle Brake Control
;----------------------------------------------------------------
;use the output to release or engage the spindle brake
IF (Aux3Key_I || KbAux3Key_M || SkinAux3_M_SV) THEN (BrakeOneShot_PD)
IF (BrakeOneShot_PD ^ BrakeMode_M) THEN (BrakeMode_M), (Aux3LED_O)
IF SpindleEnableOut_O || (!SpindleEnableOut_O && !BrakeMode_M) THEN SET SpindleBrakeRelease_O
IF (!SpindleEnableOut_O && BrakeMode_M) THEN RST SpindleBrakeRelease_O

SpindleStopped_T IS T123

IF !SpindleEnableOut_O THEN SpindleStopped_T = 5000, SET SpindleStopped_T
IF SpindleEnableOut_O THEN RST SpindleStopped_T
IF !(BrakeMode_M && SpindleStopped_T) THEN (SpindleBrakeRelease_O)

I get an error message that states too many errors when I try to compile. Here is just the last three.

Too many errors

It's the first error that's important. Sometimes a missed semicolon or a misspelled keyword can generate a ton of follow on errors.

[cncsnw]

When I wrote "... IS T123", that was just intended as a place holder. You need to enter any timer number that has not already been used in your particular PLC program.

There are only 64 timers available, so the value you actually use needs to be between T1 and T64.

I changed the Timer to T24 but still get all the ones below. I havn't changed anything in that part of the code.

So I tried to compile my original SRC file and I am getting all the same errors. How did it work before and not now?

You might try the latest mpucomp compiler. You are trying to compile the latest source code and all it's new extensions with a compiler that is 9 years old.

If you want to use the latest PLC programs, you need the latest CNC12 as well which will give you the latest PLC compiler.

Hire Marc Leonard (cncsnw) to take care of this for you....your time is worth something.
I asked mark to modify the Spindle Brake PLC to include a user definable timer in parameters.
Traditional knee mills with pneumatically actuated brakes. I did not want the brake to be slammed on after an M5 coming from 4Krpm.
I wanted to give the VFD a chance to brake the spindle and slow it before the brake was applied.

Just my experience. Personally, I think Centroid should make that a stock feature in the spindle brake plc....
