STEPPER DRIVER Summarize Max. driver current 3.5A / phase , 8 kinds of alternative current 2~125 steps, 15 kinds of alternative microsteps Input pulse Power Supplier Driver Mode constant current and chopped wave All of input signals are passed photo-isolation Auto decrease half current when motor stops CURRENT SETTING Static current is controlled by SW4 : Half current : One second after step signal stops, the motor’s phase current will be decreased 40% , the temperature is also dropped. In using the accumulator, it will decrease the wastage. SW4 : on=>full current , off=>half current Input voltage(V) Input logistic current Output phase current Step pulse Insulated resistance

Driver Connection A complete stepper motor control system contains stepper motor, step driver, DC power and controller , the following is standard connection diagram Frequency signal control Direction signal Free or high frequency Ground DC +14V~+40V (best +24VDC~40VDC) AC +10V~+29V (best +20VAC~29VAC) Motor A phase Running Condition Cooling mode Natural cooling and fan cooling place Running condition Avoiding dust, oil smog and corrosive gas Store temperature

Mechanical Dimensions Motor Connection DS8601 driver applies for the motor with two phase or four phase in four lines, six lines and eight lines, phase current is down 6A Stepping motor A phase Pin 3 &Pin 4 in P2 B phase Pin 5& Pin 6 in P2 The following diagram is showed for connection of 4 lines,6 lines and 8 lines motor :
