1. Introduction,Featuresand Applications
Introduction
The3DM683isaversatilityfullydigitalsteppingdriverbasedon aDSP withadvancedcontrol
algorithm.The3DM683isthenextgeneration ofdigitalsteppingmotorcontrols.Itbringsa
uniquelevelofsystemsmoothness,providingoptimumtorqueand nullsmid-rangeinstability.
Motorself-testandparameterauto-setuptechnologyoffersoptimumresponseswithdifferent
motorsand easy-to-use.Thedrivenmotorscanrunwithmuchsmallernoise,lowerheating,
smoothermovement thanmost ofthedriversinthemarkets. Itsuniquefeaturesmakethe3DM683
anidealsolutionforapplicationsthatrequirelow-speedsmoothness.
Features
l Anti-Resonance, provides optimum torque
and nulls mid-range instability
l Motor self-test and parameter auto-setup
technology, offers optimum responses with
different motors
l Multi-Stepping allows alow resolution step
input to produce a higher microstep output
for smooth system performance
l Microstep resolutions programmable, from
200 to 102,400 steps/rev
l Supply voltage upto +60VDC
l Output current programmable, from 0.5A to
8.3A
l Pulse input frequency up to 200 KHz
l TTL compatible and opticallyisolated input
l Automaticidle-current reduction
l Suitable for 3/6 leads Three-phase motors
l Support PUL/DIR and CW/CCW modes
l Over-voltage, over-current, phase-error
protections
Applications
Suitable for a wide range of stepping motors, from NEMA frame size 17 to 34. It can be used in
various kinds of machines, such as laser cutters, laser markers, high precision X-Y tables, labeling
machines, and so on. Its unique features make the 3DM683 an ideal solution for applications that
require both low-speed smoothness and high speed performances.

Although 3DM683 is a 3-phase stepper drive, it drives a 3-phase stepper motor 200 steps (1.8 degree)
in full step mode, same as a 2-phase stepper drive. So, there is no need for control system configuation
change when switching from 2-phase stepper system. But 3-phase stepper drive can drive a 3-phase
stepper motor smoother, quieter, and with better higher speed torque.

RegulatedorUnregulatedPowerSupply

unregulatedpowersuppliesarepreferredduetotheirabilitytowithstandcurrentsurge.Ifregulated
powersupplies(suchasmostswitchingsupplies.)areindeedused,itisimportanttohavelarge

motor-driveroperation. Ontheotherhand,ifunregulatedsupplyisused, onemayuseapowersupply
oflowercurrent ratingthanthatofmotor(typically50%～70%ofmotorcurrent).Thereasonisthat
thedriverdrawscurrentfromthepowersupplycapacitoroftheunregulatedsupplyonlyduringthe
ON duration ofthePWMcycle,butnotduringtheOFFduration.Therefore,theaveragecurrent
withdrawnfrompowersupplyisconsiderablyless thanmotorcurrent.Forexample,two3Amotors
