WAITENABLE:

WAIT UNTIL IN_A3 ; wait until A3 - hardware “enable” closed

ENABLE ; enable/start drive (& brake if assigned)

WAIT TIME 1000 ; wait 1 second to release brake

OUT2 = 1 ; Release Brake

WAIT TIME 1000 ; Wait 1 sec.

VAR_REFERENCE = 0 ; external reference for speed control

OUT1 = 0 ; clear “fault” outputs

V0 = 0

Again:

; Empty loop does nothing while the motor spins

GOTO Again ; execute motions in the loop

END ; shouldn’t get here anyway

;-------------------------------------------------------------------------------

;The Fault handling code below directs the code execution here when a fault

occurs

;-------------------------------------------------------------------------------

PROCESSFAULT:

V0 = DFAULTS ; do this so you can see that it was a fault

OUT1 = 1 ; indicate fault on LED output too

IF DFAULTS == 36 ; user switch disabled

IREF = 0 ; set internal speed reference to zero

VAR_REFERENCE = 1 ; select Internal reference

WAIT TIME 1000 ; Wait 1 sec. (for motor to stop)

OUT2 = 0 ; engage Brake

DISABLE ; disable outputs (incl. brake if assigned)

GOTO START ; reinitialize and wait for user to enable

ENDIF

GOTO WAITENABLE ; continue program
