Function–Allowstheusertoselectoneofthe5builtinfunctions.Trackisnotlistedbecauseit
isalwaysavailablewithoutaccessingthemenu.
Record Rate – Allows the user to selectfrom a list of sample rates for use with therecording
functions.
EnablePeakLogging–Allowstheusertoenableordisablepeaklogging.Normallythiswould
beenabled,butinsomeinstances,theuserwantstoevaluatelimitsonlywithoutstoringpeaks.
BydisablingPeakLogging,thePMAC3000willpeakeventsindefinitelywithoutthepossibilityof
fillingthememoryandrequiringuserinteraction.

Under Analog Settings, the user may set up everything needed to define a process to be
monitoredorcontrolled.
UnitType–Thisselectionallowstheusertochooseunitsfrompredefinedtypes.Force,Torque
orDisplacement.
Units – This selection allows the user to choose the engineering units to be used for a given
process.Theseunitsmayormaynotbethesameastheengineeringunitsinwhichthesensoris
calibrated.
ZeroMode–Allowstheuserto
selectbetweenAbsoluteandRelativezero.
Threshold–Thisvalueisusedinallthepeakfunctionsaswellastheautomaticrecordfunction.
Itdefinestheloadatwhichtheprocessstarts.
LowLimit–Thislimitvaluedrawsa linebetweenpassandfail onthelowersideof
theacceptable
bandofload.Thisvalueismagnitudeonly.Thesignisnotevaluated.
Target–ThisvaluedeterminesatwhichloadthetargetoutputintheDigitalI/Obecomesactive.
High Limit – This limit value draws a  line between pass and fail on the upper side of the
acceptablebandofload.Thisvalueismagnitudeonly.Thesignisnotevaluated.

Note:RegardingLimits…Limitsarejustnumbers.Theyarenotchangedbytheapplicationwhen
differentengineeringunitsareselected.Forexample,ifasensorisconnectedthatisdisplayed
ininlb,andtheThresholdvalueis5.0,thentheprocesswilltriggerat5.0inlb.Iftheengineering
unitsarethenchangedtoftlb,theprocesswillnowtriggerat5.0ftlb.Thisbehaviorisconsistent
foralllimits,includingtheTarget.ItalsoappliestotheEncoderSettings.

UnderEncoderSettings(encoderenableddevices
only),theusermayfurtherdefineaprocessto
bemonitoredorcontrolled.Non‐encoderenableddeviceswillshowtheseitemsdisabled.
Mode–Thisselectionallowstheusertochooseoneofthreeencodermodes;Off,DegorRPM.
LowLimit–Thislimitvaluedrawsa linebetweenpassandfail onthelowersideoftheacceptable
rangeoftheencoder,beitAngleindegrees,orRPM.
Target–ThisvaluedeterminesatwhichAngleorRPMthatthetargetoutputintheDigitalI/O
becomesactive.
High Limit – This limit value draws a  line between
 pass and fail on the upper side of the
acceptablerangeoftheencoder,beitAngleindegrees,orRPM.
