CongratulationsonpurchasinganOriginalLineElectricactuatorfrom
Bimba. Our OLE actuators are designed, built, and tested to provide the
longestlife,greatestdurability,highestspeed,andgreatestthrustper
dollar.Welookforwardtoservingyourelectricactuatorneedswiththe
same responsiveness and engineering expertise you are accustomed to
receivingforourpneumaticproducts.
EveryOLEactuatorisbackedbyaone-yearwarranty.Extendittoatwo-
yearwarrantybyregisteringonourwebsiteat
www.bimba.com/pdf/OLEwarrantyregistration.pdf.

TheDRV-4acceptspowersupplyvoltagesfrom24to48VDC,whilethe
DRV-8acceptspowersupplyvoltagesfrom24to75VDC.Thecurrent
demandwillneverexceeddoublethemotorcurrent(seeTable3,Amps
column).However,theDRVwillconvertahighvoltagelowcurrentpower
supplyintoalowervoltagehighercurrentpowersupply.A24V4Asupplywill
performsimilarlytoa48V2Asupply.UseTable7belowasaguideline.
!
Warning:Donotapplypoweruntilallconnectionsaremade.
!
Useunregulatedpowersupplieswithoutovervoltageprotection
toavoidproblemswithregenerationduringrapiddeceleration.

b. Connect the DC power supply to the driver -- Do not
apply power
I.Makesurethepowersupplyisnoton.ConnectV+andV-fromthe 
 powersupplytotheV+andV-terminalsofyourdriver.
II. Ensure a proper earth ground connection by
 usingthescrewontheleftsideofthechassis.
Ifusinganexternalfuse,werecommendthe
followingin-linewiththeV+connection:

k. Set step pulse type
Mostindexersandmotioncontrollersprovidemotioncommandsinthe“Step
andDirection”format.TheStepsignalpulsesonceforeachmotorstepand
thedirectionsignalcommandsdirection.However,afewPLCsuseadiffer-
enttypeofcommandsignal:onesignalpulsesonceforeachdesiredstepin
theclockwisedirection(calledSTEPCW),whileasecondsignalpulsesfor
counterclockwisemotion(STEPCCW).Thedrivescanacceptthistypeof
signalifyouremovethecoverandmovejumperS3fromthe“1-2”positionto
the“1-3”position.Factorydefaultisthe1-2position.Asyoucanseeinthe
image,thejumperterminals(2,1,3)andS3andS4designatorsareprinted
inwhiteonthecircuitboard.
l. Step pulse noise lter
Electricalnoisecancausethedrivetothinkthatonesteppulseistwoor
more pulses, resulting in extra motion and inaccurate motor and load posi-
tioning.Tocombatthisproblem,thedriveincludesadigitalnoiselteronthe
STEPandDIRinputs.Thedefaultfactorysettingofthislteris150kHz.
Ifyouareoperatingthedriveathighspeedswithstepratesabove150kHz,
removethecoverandmovejumperS4fromthe150kHzposition(1-3)tothe
2MHzposition(1-2)asshownbelow.
Yourmaximumpulseratewillbethehighestmotorspeedtimesthesteps/
rev. For example, 40 revs/second at 20,000 steps/rev is 40 x 20,000 = 800
kHz.Pleaseconsiderthiswhendecidingifyoumustincreasethelterfre-
quency.

Troubleshooting Guide and FAQ
Problem:Actuatordoesnotmovewhenstepmotorisenergized.
Solution:Stepmotorwindingsmaybeshorted.UseanOhmmeterto
measuretheresistancebetweenpairsofwindings(shouldbeinnite)
andbetweentheleadsofeachwinding(shouldbethesameforeach
winding).Useyourmotor’swiringdiagramtoidentifythecorrectleads.
Ifwindingsareshorted,themotormustbereplaced.
Problem:Actuatoroperationisstiff,seemstobebinding.
Solution:Checkfordentsonthebodytube,motorendbell,anddam-
agetothesquarerod.Iftherearesignsofvisibledamage,theactuator
ormotororbothmayneedtobereplaced.Dentsonthemotorshaftor
endbellsmaycausetherotortoseizeorrub,producingbindingandstiff
operation.WhilethenutoftheOLEactuatorisself-lubricating,rodlubri-
cations is recommended at regular intervals. Use Bimba HT-99 grease.
Problem:CanIuseswitcheswithmyOLEforendofstrokesensing?
Solution: All OLE actuators have magnetic pistons. OLE actuators can
usethesameswitchesasOriginalLinepneumaticcylinders.Refertothe
Bimbacatalogforswitchrecommendations.
Problem: The motor gets hot.
Solution:Stepmotorstendtorunhot(theactualmaximumcasetem-
peratureis80°C).However,themotorshouldnotgettoohottotouch.
Ifitisoverheating,thedrivecurrentmaybesettoohigh.Allstandard
OLEstepmotorsare8-wiremotors.RefertoTable3inthismanualfor
requireddrivecurrentlevels.Alsoconsiderdutycycle;reduceeitherthe
runningcurrent,idlecurrent,ordutycycle.Instructionsforadjustingidle
and running current are provided in section 3.e.
Problem:Themotorisnotproducingenoughtorqueoritstallsatlow
speeds.
Solution:Ifthemotorpreviouslyranwell,checktheresistanceofthe
windings.UseanOhmmetertomeasuretheresistancebetweendiffer-
entwindings(shouldbeinnite)andbetweentheleadsofeachwinding
(shouldbethesameforeachwinding).Useyourmotor’swiringdiagram
toidentifythecorrectleads.Ifwindingsareshorted,themotormustbe
replaced.
Iflackoftorqueisobservedattheinitialstartupwithaloadanddesired
speedsarenotreached,checkconnectionsbetweenthemotoranddrive
and check drive settings.

Inspectthemotorandrotatetheshaftwhenthemotorisnotconnected.If
youfeelanyrubbingorthereareanydentsonthemotor,thereisprob-
ably an alignment problem and the motor may need to be replaced.
Iftherotorwasremovedfromthestator,itcouldhavebeendemagne-
tized.Themotorwouldneedtobereplaced.
Ifyoustillcannotsolvetheproblem,thesizeofyourpowersupply(volt-
ageoutput)mayneedtobegreater.Whenastepmotorrotates,itacts
likeageneratorpumpingvoltage(backEMF)backintothedrive.Back
EMF rises as motor speed and inductance increase and can cause a stall.
Thesolutionistoeitherchangefromaseriestoaparallelconnection
(seriesconnectionsquadrupleinductance)oruseapowersupplywitha
higher output voltage.
Problem: Themotordoesn’tproduceanyholdingtorque.
Solution: Makesurethatlinepowerison,thedriveispoweredup,and
the motor phases are connected correctly to the drive.
Problem:Themotor(actuator)oscillatesbackandforthatlowspeeds.
Solution: Thisisduetoresonance,commonbetween1-4rps.Ifthisis
observedwithnoload,addaloadtothemotor(theloadwilldampenout
resonance).Changingfromfull-steptohalf-stepormicrosteppingwillalso
solve resonance problems.
Step and Direction Drives
Note:Pleasereadyourmanualrstbeforeandduringyoursetup.Bimba
manuals, available at www.bimba.com/OLE/manuals, are short, to the
point, and comprehensive.
Problem:Thedrive’spowerLEDdoesnotilluminatewhenpowerisap-
plied.
Solution:Checkthefuseandreplaceifnecessarywithoneoftheextra
fusesincludedwithyourdrive.Ifyouhavenofusesorcontinuouslyblow
fuses,callBimbaTechnicalSupport.Checkyourpowersupplytobesure
it is not providing an excessively high voltage to the drive.
Problem: The motor runs then suddenly dies. The connections are cor-
rect.
Solution:Turnoffpower.Refertoyourmotorwiringdiagram.Discon-
nectthemotor.Usinganohmmeter,measuretheresistancebetweenthe
A+ and A- and B+ and B- terminals. The reading should be in the mega-
Ohms.Ifresistanceislow,theH-bridgeisdamagedandthedrivemust
bereturnedonaRGA(ReturnedGoodAuthorization).Iftheresistanceis
normal,inspecttheboardforanyvisibledamagetothecomponentsand
checkthemotorforashortcircuitinthewindings.

Problem: Themotordoesnotmovewhenastepsignalissenttothe
drive.
Solution: Iftheenableinputison(lowwithrespecttoa5-24voltsignal),
itwilldisablethemotor.Donotconnectanythingtotheenableinputif
there is no reason to disable the motor.
Problem: Themotorwillnotrunslowenoughwithapotentiometercon-
nectedtomydrive(ithasaninternaloscillator).
Solution:Somedrives’internalpotentiometerscannotbeadjustedto
zerospeed.Checkthespecicationsinthemanualthatcamewiththe
drive.
Problem:Atstartup,themotordoesnotrunalthoughthewiringiscor-
rect.
Solution:Makesurethatdipswitchesandjumpersaresetproperly.
Readyourdrivermanualcarefully.
Problem:Systemnotworkingproperly.
Solution: Troubleshootbyreplacingthedriveandseeiftheproblem
persists.Pleasereadyourdrivemanualbeforeandduringyoursetup.
