Producing Trigger Outputs
Therearethreedifferentmethodstoproduceapulseatanexactposition:
1.
Indextoaposition,thenwhilestoppeduse“PA”,“U1”, or“U5”/”U4”command.
2.
UsetheContinuousindexingmethodwiththe“ “commandtoproduceapulse
outinsteadofstoppingattheend
ofindexes.
3.
SetVXMtoPulseevery“n”(”n”isanumberfrom0to32,767)numberofsteps

Pulsewidthissettablewiththe
commanddescribedonpage43(defaultwidthis10msec.)

U7
StartofContinuousIndexwithpulseoutput. Thiscommandisusedwhenitis
desirabletomakeseveralIndexesononeaxiswithoutstoppingorslowing
betweeneachIndex. Insteadofstoppingapositivegoingpulsewillappearon
useroutput2(I/O,15)ateachIndexdistance.
Thispulse
wouldbeusedto
triggermeasurement/samplingequipment. The" "or"
"
commandmustbeusedasthelastcommandtodeceleratetoastopfromthe
lastIndex.
Memoryusage=2bytes.
ContinuousIndexeshavethefollowinglimitations:
a)
EachIndexmustbethesamemotor,anddirectionshouldnotbechanged
unlessspeedisbelow
800steps/sec.
b)
Onlymotors1and2canberuninthismode
c)
Theaccelerationvaluesetbeforethe“U7”commandwillbeusedinthe
continuousindex.
d)
Speed settings, Jumps, Loops, and Output commands can be used
betweenindexes. PausesandWaitcommandsarenotallowed.
