2 Phase Hybrid Stepping Motor Driver

The specifications are believed to be accurate and

reliable. However, the suitability has to be determined

for a specific application. Specifications are subject to

change without notice.

Notice: according to the five connecting ways above drawing, should set the current, in theory the higher

current, the higher torque. But for reason that the motor avoid to lose the steps and rise high temperature in

high speed, general in this mode of the high speed output set the output current 1.4 more than the motor rated

phase current, in this mode of the high torque output set the output current is the motor rated phase current

70%.in actual, the setting phase current state is that the motor driver temperature inside 80 degrees in

working.

3. control signals are connected

PC control signal be high, also be low effective. When active high, the negative side of all control signals

together as a signal to active low, positive side of all control signals together as a signal common. Open-

collector, PNP output and differential signal output, for example, the interface circuit diagram is as follows

Controller NPN output (anode meet method)

Notice:



VCC = 5V, R short



VCC value of 12 V, R 1K greater than 1/8 W resistor



VCC value of 24V, R 2K, than 1/8 W resistor


