Control signal interface:

name	illustrate
PUL+	Pulse control signal: pulse rising edge is effective; PUL-4~5V at high level, 0~0.5V at low level. For reliable response to impulse signals, the pulse width should be greater than 1.2μs. If +12V or +24V is used, a string resistor is required.
PUL-
DIR+	When the input mode is pulse + direction, as a direction signal: high/low level signal, in order to ensure reliable commutation of the motor, the direction signal should be established at least 5μs before the pulse signal. The initial running direction of the motor is related to the wiring of the motor, and the exchange of any phase winding (such as A+, A- exchange) can change the direction of the initial operation of the motor, DIR-4~5V at high level, 0~0.5V at low level. If +12V or +24V is used, a string resistor is required.
DIR-
ENA+	Enable signal: This input signal is used to enable or disable. When ENA+ is connected to +5V, ENA- is connected to low (or internal optocoupler on), the driver will cut off the current of each phase of the motor so that the motor is in a free state, and the step pulse is not responded. When this function is not needed, the enable signal can be left in the air.
EAA-
FAU+	Positive alarm output
FAU-	The alarm output is negative

The product is widely used in woodworking engraving machines, CNC machine tools, computer embroidery machines, packaging equipment, ceramic equipment and laser cutting equipment.

Computer embroidery machine is the most advanced embroidery machine in contemporary times, which can make the traditional manual embroidery achieve high speed and high efficiency, and can also achieve the requirements of “multi-level, multi-functional, unified and perfect” that manual embroidery cannot achieve.

It is a kind of mechanical and electrical products reflecting a variety of high-tech China’s domestic computer embroidery machine is mainly a high-end model, compared with the above international brands, there is still a certain gap, mainly in terms of process technology and materials, domestic machines can not be compared with these high-end brands, manifested as service life, wire breaking rate, embroidery accuracy and other differences.

However, due to the relatively low price of domestic computer embroidery machines, the development speed has been rapid in recent years, occupying most of the market share, motors and drives can use Chinese manufacturers (motorforum.rfidepc.com) this combination.

Automatic packaging machines are generally divided into two types: semi-automatic packaging machines and fully automatic charter machines. Automatic packaging machine is mainly used for automatic packaging of materials in food, medicine, chemical and other industries and plant seeds. Materials can be granules, tablets, liquids, powders, pastes, etc.

The automatic packaging machine has the functions of automatic measurement, filling, bag making, sealing, cutting, conveying, printing production batch numbers, adding easy incision, no material warning, stirring and so on.

The automatic packaging machine has advanced design, reasonable structure and reliable performance.

The automatic packaging machine adopts double synchronous belt pulling film, which is controlled by the cylinder tensioning, automatic correction, automatic alarm protection function, and minimizes loss.

The measuring device is matched, integrating bag making, filling, filling, printing and counting. The metering device can be modified according to the material.

It can be used with drives and motors from Chinese manufacturers (motorforum.rfidepc.com).

Matching our stepper motors: 86mm two-phase hybrid stepper motor, 110mm two-phase hybrid stepper motor.
