Description:
- HYQD60 - H4200 is a professional of two-phase stepper motor drive, can achieve positive and negative control. Via the S4, S5 S6 three dial the code switch selection of gear subdivided control (1, 2, 4, 8, 16, 32, 64, 128), via the S1 S2 S3 three dial the code switch to choose A six-speed current control (0.3 A, 0.6 A, 0.9 A, 1.2 A, 1.5 A, 1.8 A). Suitable for driving 42,39,35,28,20 two phase, four phase hybrid stepping motors. Drive with low noise, little vibration, the characteristics of stable operation

Power supply voltage
VCC: power positive end "+"
GND: power negative "-"

Input terminal connection
Three channels foe input signals, they are: step into the pulse signal CP+, CP-; the direction level siganl DIR+, DIR-; offline signal EN+, EN-. The input signal interface has two kinds of connection method, the user can use the common anode or the common cathode method.

Common anode connection: respectively, connect CP +, DIR+, EN+ to the ground of the power supply control system, if the power supply is 5V can directly access, if the power supply is greater than 5V must be external plus a current limiting resistor R to ensure to Internal Drive Optocoupler provides 8 - 15mA of drive current. Pulse input signal through CP- access, the direction of the signal through DIR- access, so that the signal through EN- access.

Common cathode connection method:, CP-, DIR-, EN- is connected to the ground terminal of the control system; the pulse input signal is connected with CP+ through EN+, and the direction signal is connected with the DIR+. If the limiting current resistance, the R of the limiting resistance is the same as that of the common anode.

Note: EN can not be connected to the EN, when the EN is effective, the motor rotor is in a free state (offline state), then you can manually rotate the motor shaft, do your adjustment. After the completion of the manual adjustment, the EN is set to an invalid state, in order to continue the automatic control
