1. The ND2282 is a high performance and low noise microstepping driver based on pure sinusoidal current control technology It s suitable for driving 2 phase and 4 phase hybrid stepping motors By using advanced bipolar constant current chopping technique the ND2282 can output more torque than other drivers at high speed The microstep capability allows stepping motors to run at higher smoothness less vibration and lower noise Its pure sinusoidal current control technology allows coil current to be well controlled with relatively small current ripple therefore smaller motor noise and less motor heating can be achieved In addition the ND2282 has a built in EMI filter which can make the driver operate with higher reliability Features High quality cost effective Input frequency up to 200KHz Low motor noise and heating 15 microstep resolutions selectable Supply voltage up to 220VAC 310VDC Suitable for 2 phase and 4 phase stepping Output current up to 8 2A 5 86 ARMS motors TTL compatible and Opto isolated inputs DIP switch microstep amp current settings Automatic idle current reduction Support PUL DIR amp CW CCW modes Applications Suitable for large and medium automation machines and equipments such as engraving machines labeling machines cutting machines laser phototypesetting systems plotting instruments NC machines pick place devices and so on Particularly adapt to the applications desired with low mot2. and Applications ccccccccccssssssssssseeeccceeeeeeeeeeaeasaeesssseseeeeeeees i In odc OI oases hoes saa EEEE EAE Feature Soane e occtees cen ease deci T EEE don aca T EES APPEAU INS si su Sa cps aac ie a athe ed Ac eee er a Ee a i De SC CIICALIONS T E E E EE E E E E S E E E Electrical Specifications cath cccadesssoseuceaceasdsnsaciaussscssacses dps eaceunlsareutsacracs areas i Mechanical Speci Cations sei E 2 Operating Environment and Other Specifications cccccsseeceeeeeeeeeeeeeeeaaeeeeeeees 2 a COON CA E TA E TEE A E N E 2 3 Pn ASSignment and Descripuon tisciie det uie seed b ei duMadeie die huien 3 Connector PI Conic tat Ons ers seesaw tacos a aeieae sone Rese ceee stseds 3 Connector P2 Conf surao esir latch an aati natasha E 3 4 Control Signal Connector P1 Interface cc cecsessssseeeeeceeeeeeeeeeeaesseeeessseeeeeeeeees 4 5 Comme ctmg Me MOON esseed 4 Connections 16 4 lead MOOS creien A R RNE 5 Connections to G leadi MOLES soirassa a a ae aed ees 5 aie COC Oni e wao cases sesnsin cess ss ose rarniaseun ecresea tae china nce ecto 5 Full Coil Conheuranons ani ienian inane eee 5 COMME CHIOMS to S216 ad Molor S aaseaesisastacen aes satetcan tata Get sxdecasseaasaulendocaetinceGehescvastsee 6 Series ONNCCUONS we tacmeare eae a amie 6 Parallel Connec NOn y 5 ices a nde tonite ee 6 6 Power Supply SCLC CH OMS snare EAE ARER 7 DEE CHING Supply Volpe ee E S AE E 7 7 Selecting Microstep Resolutio
