2-Phase 57 42 Stepper Motor Driver HYQD20-H5700 DC42V 4A 128 Subdivision LV8727

Brief introduction:
HYQD20-5742It is a professional two-phase stepper motor driver.Reversing control can be achieved by 3 Location DIP switch, select 8Files subdivision control(2,8,16,32,64,128,10,20)By 3DIP switch option, Choose 6File current control (0.5A,1A,1.5A,2A,2.5A,3A, 3.5A, 4A). Suitable for driver 57,42Two - Phase, four-phase hybrid stepping motor. To achieve low vibration, low noise, high speed drive motor effects.

Features:
- Power supply with anti-reverse function
- Current generated by DIP switch selectable
- Interface with high-speed optocoupler isolation
- Eight kinds of adjustable subdivision
- Automatic semi-flow
- High integration and high reliability
- Anti-high-frequency interference ability
- Maximum pressureDC 42V

Input and output terminals Description:
The signal input terminal
CP +: Pulse signal input positive terminal.
CP-: Pulse signal input negative terminal.
U / D +: The motor clockwise and counter-clockwise controls positive.
U / D-: The motor clockwise and counter-clockwise controls negative terminal.
EN +: Motor offline control the positive terminal.
EN-: Motor offline control the negative terminal.

Motor winding connection:
A +: Connect the motor windingsA +Phase.
A-: Connect the motor windingsA-Phase.
B +: Connect the motor windingsB +Phase.
B-: Connect the motor windingsB-Phase.

Operating voltage connection:
VCC: Connecting the DC power supply positive (note:10V<VCC<42V).
GND: Connecting the DC power supply negative.

The input wiring instructions:
There are three-way input signal, they are: pulse signalCP +,CP-; direction level signalDIR +,DIR- off signalEN +,EN-. Input signal interface has two configurations: the user can employ a total of Yang needed Pole connection or common cathode connection.
Common anode connection: respectively, connect CP +,DIR +,EN + to the control system of the power supply, if This power is+ 5VIt can directly access, if this power is greater than+ 5VIt shall be an additional external current limiting resistor R, Guaranteed to drive internal optical coupling provided8-15mADrive current. Pulse input signal CP-Access,
Common cathode connection: respectively,CP-,DIR-,EN-Connected to the control system of the ground terminal; pulse input signalCP +Access direction signalDIR +Access enable signalEN +Access. For current limiting resistor, current limiting resistorRThe connection of the same values and common anode connection

Note:EN can be disconnected,EN is effective, rotor is in a free state (offline), then you can manually rotate the motor shaft, make it fit your adjustment. After manual adjustment is completed, and then make EN an inactive state in order to continue automatic control
When Drive controller and wiring, motors, power supply to common anode connection,Please disconnect the power wiring, motor wiring should pay attention not to the wrong, the inner phase phase short circuit, so as not to damage the drive.

Synchronous rectification:
By the DIP switch S1 selecting,when PWM is off, motor coil will remain some of the electromotive force.You can choose from an external Schottky diode to release remaining emf; you can also choose an appropriate timeCarved open simultaneously two lower legmosfetTo free EMF.S1PutONWhen openSRFunction, choose to open the two lower leg at the appropriate timemosfetTo release the force.S1 switch is OF,  close the SR function, the Schottky diode connected externally to release the force.

Package included:
- 1 x Step Driver
