ThischapterwillpresentabriefintroductiononhowtotestandoperateanAZservodrive.Readthroughthis
entiresectionbeforeattemptingtotestthedriveormakeanyconnections.
Getting Started
TobeginoperationwithyourAZdrive,besuretoreadandunderstandthepreviouschapters
inthismanualaswellasthedrivedatasheet.Besurethatallsystemspecificationsand
requirementshavebeenmet,andbecomefamiliarwiththecapabilitiesandfunctionsofthe
AZdrive.Also,beawareofthe
“Troubleshooting”sectionattheendofthismanualforsolutions
tobasicoperationissues.
Input/Output Pin Functions
ThefamilyofAZdrivesprovideanumberofvariousinputandoutputpinsforparameter
observationanddriveconfigurationoptions.Consultthedrivedatasheettoseewhich
input/outputpinfunctionsareavailableforeachdrive.
Current Monitor Output ThecurrentmonitorpinisavailableonallAZdrivemodels.Measured
relativetosignalground,itprovidesananalogvoltageoutputsignalthatisproportionaltothe
actualcurrentoutput.Thescalingfactorforeachindividualdrivecanbefoundonthedrive
datas hee t.
Example Measurement
ThecurrentmonitorpinonanAZdrivewithacurrentmonitorscalingfactorof4A/Vis
measuredtobe1.3V.Thiswouldmeanthedriveisoutputting:(4A/V)(1.3V)=5.2 A.
Current Reference Output ThecurrentreferencepinisavailableonallAZdrivemodels.
