It is designed for use with 2-phase hybrid stepper motor of all kinds with 57mm to 110mm outside diameter and less than 8.0A phase current. This circuit that it adopts is similar to the circuit of servo control which enables the motor run smoothly almost without noise and vibration. Hording torque when DQ860MA run under high speed is also significantly higher than the other two-phase driver, what’s more, the positioning accuracy is also higher. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, and computer embroider machine, packing machines and so on.Features:l High performance, low pricel Average current control, 2-phase sinusoidal output current drivel Supply voltage from 24VDC to 80VDCl Opto-isolated signal I/Ol Overvoltage, under voltage, overcorrect, phase short circuit protectionl 14 channels subdivision and automatic idle-current reductionl 8 channels output phase current settingl Offline command input terminall Motor torque is related with speed, but not related with step/revolutionl High start speedl High hording torque under high speedElectrical specification:Input voltage24-80VDCInput current＜ 6AOutput current2.8A～7.8AConsumptionConsumption：80W； Internal Insurance：10ATemperatureWorking Temperature -10～45℃；Stocking temperature -40℃～70℃HumidityNot condensation, no water dropletsgasProhibition of combustible gases and conductive dustweight500G 3, Power Supply 350W,60VDC 4, Breakout Board DB25 Description:Built in DB25 male connector.DB25 Output Pin:P1,P2,P3,P4,P5,P6,P7,P8,P9,P14,P16,P17.DB25 Input Pin: P10,P11,P12,P13,P15.DB25 GND Pin: P18-P25.Power supply: +5V DC.Built in C-class Optical-coupler.High quality with Surface-mount Tech.We ship worldwide!
