Product features:

Applied to 30V 70W DC brushless motor

Can adopt manual control mode (with a potentiometer, can also be external potentiometer to do manual speed control)

Start stop control; positive inversion control

The stable high-torque output, speed stability

Over-current, under-voltage, locked rotor, Holzer encoder returned signal error temperature protection

Main function:

under voltage (≤ 8V), heat (>95 °C) automatic protection

blockage automatic protection

Holzer error protection

support built-in potentiometer, external potentiometer and analog voltage control

has automatic braking function

Speed control mode:

The driver provides the following 3 kinds of speed control mode, the user can choose one of them.

A: Potentiometer directly adjusts speed: potentiometer is set on the driver, then rotary potentiometers can do direct adjust speed.

B: Analog voltage regulation: on the external potentiometer, we can connect VCC on one of fix ends, while another fixed end connected to the COM terminal, the control terminal is connected with the SV end "can use an external potentiometer (10K~100K) to control speed, also can reach through the other control units (such as PLC, SCM) input analog voltage to the SV terminal"

C: Speed control (compare to COM) SV port accepts 0V~+6.25V, the corresponding motor speed is 0~ rated speed. (The use of external please adjust the potentiometer position to the lowest position)

Interface definition:

PCB design is the design of printed circuit board, with circuit diagram as the basis, to achieve the functionality required by circuit designer. Mainly refers to the design of printed circuit board layout design, need to consider the layout of the external connections, the internal electronic components layout optimization, metal wires and through-hole layout optimization, electromagnetic protection, heat dissipation and other factors. Good layout can save production cost, achieve the circuit performance and good heat dissipation performance; a simple layout can be achieved by hand, complex layout needs to achieve computer aided design.

The hardware design is according to the designer needs, at the control range of cost, use the current industry mature chip solution or technology, complete with designer function, performance, power design, power, heat, noise, signal integrity, electromagnetic radiation, safety, reliability, device procurement, testing, production and other requirements hardware products within the specified time.
