1. Introduction, Featuresand Applications

1.1 Introduction

DB810isanewdigitalDCservodriverdevelopedwith theadvanced21-century

technologyintheworldtoday.Inposition control,it seasyfortheenduser to

changethestepdriver toDB810withoutchangingcontrol system,becauseitsinput

command isPUL/DIR signal,whichiscompatiblewith thatofstepdriver.In

velocitycontrol,thepositionfeedbackoftheencoder caneffectively eliminatethe

“zero-speeddrift”phenomenonwhenthe analogservo isstandstill.Inthelowpower

motion controlapplications,performances ofDCservo systemsusingDB810are

better thanthose ofdigitalACservo systemsin velocity,precision,noise,stability

and someother aspects, at leastas goodas those ofdigitalACservo systems.

Synchronously theprice ofDB810staysattheprice lineofstepdriver,namelyfar

lower thanthatofAC servo.

Before youstartservo, youcanfollowthefollowingsteps:

4.1 Install Encoder

You musthaveasuitableencoder properlymountedonthemotor.Please assemble

theencoder accordingtoitsfactorymanual.

4.2 Prepare PowerSupply

You musthave a DC power supplysuitable for the motor. Donot use apower supply

voltagemore than5voltsinexcess oftheratedvoltageofthemotor.Thepower

at.Whenthepower supplyleadislongerthan50cm,a1000uF/100Velectrolytic

capacitorshouldbeconnectedbetween the “pinPOWER GROUND”and the “pin

+18TO+80VDC”. Payattentionthatthepolaritycannot be reversed.

4.3 Prepare Controller

5.Tuning theServo

5.1 Testing the Servo

starter (a momentaryswitch).

If everythingiscorrectyou shouldhear themotor “singing”.Thisisnormal.The

motorisdithering orbouncing betweenadjacentencoder counts.Theintegralterm

in aPIDloop has infiniteDCgain over timeand will amplifyeventhesmallest

positionerror.Becauseencoder feedbackcanonlyoccuroncountedges,theloopis

“blind”untilit encountersanencodercount edge.Itthenreverses themotor

direction untilanother edge is found, then theprocess repeats.

(greater stiffness), thenincrease DAMPING isneededas well torestore critical

damping. Be careful,increasing GAINwithout increasingDAMPING maycause the

motorto breakout intoviolentoscillation.ThehigherGAINisset,thenoisier the

motorwill bewhenstopped.Thisisbecausehigher gaincauses more vigorous

dithering betweenencoder counts atrest.

6. Using Tips

6.1 CurrentLIMITSetting

ThecurrentLIMITtrimpot setsmaximumcurrentthemotorispermitted tohave.It

isadjustablefrom0ampsto 20amps. NormallytheLIMITtrimpot issetto

maximum(20 amps) unless you wanttolimit motor torque toa lower value.

More speedand position isunaffectedby the currentLIMITsettingunless thetorque

demand duetoloadexceedsthissetting,thenthemotorpositionwillfall behindthe

Tel: (86)755-26471182Fax: (86)755-26402718URL: www.leadshine.com

command position becauseof insufficient torque.

6.2 Fault Indicator

NormallywhentheDB810isfirstpoweredup,itwill benecessaryto pushthe

momentaryswitchtoSTARTfor5seconds. Thiswill clear thepower-on reset

conditionandextinguishtheFAULTLED.Themotorwill thenbeenabledand the

drivewillbegintooperate.

If atanytimeafter thataconditionoccursthatcausestheDB810to “faultout”,such

as notbeingabletocompleteastepcommand,theERR/RES terminalwill goto “0”,

signalingthecomputer an errorhasoccurred.Thiswill require theoperatorto

correcttheproblemthatcausedthefaultandthenpushtheswitchto “START”for5

secondsto re-enablethe DB810.

Atanytimetheoperatorcan pushtheswitchtothe “STOP”positiontoimmediately

halttheDB810drive. AnytimetheDB810 is inthe “FAULT”state(FAULTLEDlit),

all switchingaction stopsandthe motor freewheels and is unpowered.This willlight

the “FAULT”light.

TheFAULTindicatorison whilethedriveisinpower-onreset,theDISABLE input

isheld “low”oriftheprotectioncircuitistrippedduetoafaultcondition.Allpower

MOSFETsareturnedoffandallinternalcounters arereset.TheFAULTcondition

lastsfor3seconds, andthenself-resetstotryagain.Iftheprotectioncircuittripped

it andthecause isnotcleared,thenit will immediately re-enter the FAULTstate

again andrepeatthecycle.

There are two conditionsthatwilltrip theprotection circuit.Onecondition isifa

short-circuitoccurs andcurrent exceeds 20amps.

Theother conditionisifthePOSITIONERRORexceeds+/-128countscausinga

breakoftheservo-lock.This condition canhaveseveralcauses:

1). Theloopsettingsareseverelyunder-dampedand themotorbreaksoutinto

oscillation.

2). Excessivemotor loaddue toacceleration or workload.

3). The speedcommand in excess of whatthe motor candeliver.

4). The currentLIMITisset toolow.

5). Thepowersupplycurrentisinsufficientfor thedemand.

6). The motor is wiredbackwards, isbrokenor disconnected.

7). Encoder failure.

6.3 Reversing Default MotorDirection

TheDB810will turnthemotorintheCWdirectionwhentheDIRECTION inputis

“high”(logical “1”,or +5VDC). If insteadCCWispreferred, then:

1) Reverse themotor “+”and “-”leads

2) Reverse theencoder “ChannelA”and “ChannelB”leads

6.4 ERR/RES

Thisterminalfunctionsas anERRORoutputandasaRESETinput.Because this

terminalfunctionsas both aninput andanoutput,somedetailed description is

necessary.

WhenfirsttestingtheDB810,ERR/RES (term.5)was connectedto E+5V(term.7).

Itcanbeleftthatwayifitisnotnecessaryto readthestateoftheERRORoutput.

Otherwise, the followingdetailsare important.

TheERRORoutputislatchedinthe “ERROR”state(term.5=0)by thepower-on

resetcircuitryin theDB810.Itwill stayin thisstateindefinitelyuntilitisclearedby

applying+5Vto thisterminalfor atleast5seconds.

Thevoltageonthisterminalgoes to 0VDCwhenevertheFAULTindicatorislit.

Thisoutput canbe usedto signalyourcontroller thatanerror has occurred.
