;------------------------------ Main Program ------------------------------
S1 CONT ;Activate scan for Stop input
DISABLE ;Disable IQ to allow operator to move motor
; shaft to load the part
ALL OFF ;Clear all outputs
Ready = ON ;Signal ready for a new part
Timerdone = OFF ;Clear timer
Begin: ;Beginning of test loop
WAIT Testcomplete = OFF ;Wait for host to read data and clear flag
WAIT Starttest = ON ;Wait for start input
ALL OFF ;Clear all outputs
ENABLE ;Enable IQ
;Check to see which test to perform and jump to the
; proper section ON Testnumber JUMP Setuperr, Begin1,
; Begin2, Begin3, Begin4
Setuperr:
Setuperror = ON ;Signal error in test data
DISABLE ;Disable IQ
JUMP Begin ;Go back to beginning
;Test 1 - Measure torque at a fixed velocity
Begin1:

WAIT Timerdone = ON ;Wait for timer to finish
Meascurrent = ICMD ;Read current
MOVV = 0 ;Stop motion
DISABLE ;Disable IQ
