APPENDIXES

;------------------------------ 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:

IF Testvel <= 0 JUMP Setuperr

;Check if valid velocity

IF Maxtorque <= 0 JUMP Setuperr

;Check if valid tolerance

IF Mintorque < 0 JUMP Setuperr

;Check if valid tolerance

TIMER1 = Testdelay

;Set timer value

S2 ON

;Start timer scanned event

Starttimer = ON

;Start timer

MOVV = Testvel

;Start motion

WAIT Timerdone = ON

;Wait for timer to finish

Meascurrent = ICMD

;Read current

MOVV = 0

;Stop motion

DISABLE

;Disable IQ

Test1torque = Meascurrent

;Calculate torque

* Torqueconst

IF Test1torque > Maxtorque

;Check if torque within tolerance

Fail = ON

; if not - the part fails

ELSE

{

IF Test1torque > Mintorque

Pass = ON

; otherwise - the part passes

ELSE

Fail = ON

}

JUMP Done

;Finish the test

;Test 2 - Stress test

Begin2:

IF Testvel <= 0 JUMP Setuperr

;Check if valid velocity

IF Maxdistance <= 0

;Check if valid tolerance

JUMP Setuperr

IF Currentlimit <= 0

;Check if valid Ilimit

JUMP Setuperr

ILIMIT = Currentlimit

;Set current limit

Startpos = PCMD

;Capture starting position

Targetpos = PCMD + Maxdistance

;Calculate minimum move distance

TIMER1 = Testdelay

;Set timer value

S2 ON

;Start timer scanned event

Starttimer = ON

;Start timer

MOVV = Testvel

;Start moving

WAIT PCMD >= Targetpos

;Wait until commanded motion reaches target
