DVS3722B 3 phases 220vac 7A stepper driver with performance

Port	Connector pin No.	Symbol	Functions / Applications	Definition
DB15	1	5PU+	Positive of opto-isolated input signal	Connect to +5V power supply, drive voltage ranges from 5V to +24V. Current-limiting resistance is needed when it is over 5V.
	2	PU-	DP9=OFF, PU is step pulse signal	With the falling edge of the signal PU, the motor executes an angular step. The input resistance is 220Ω. Low voltage 0-0.5V, high voltage 4-5V, pulse width>2.5μS.
			DP9=ON, PU is positive step pulse signal
	3	5DR+	Positive of opto-isolated input signal	Connect to +5V power supply, drive voltage ranges from 5V to +24V. Current-limiting resistance is needed when it is over 5V.
	4	DR-	DP9=OFF, DR is direction signal	Change the motor’s direction of rotation. Input resistance is 220Ω. Low voltage 0-0.5V, high voltage 4-5V, pulse width>2.5μS
			DP9=ON, DR is negative step pulse signal
	7	5MF+	Positive of opto-isolated input signal	Connect to +5V power supply, drive voltage ranges from 5V to +24V. Current-limiting resistance is needed when it is over 5V.
	8	MF-	Motor free signal	The motor current will be cut off and the driver stops working when it is effective.
	9	ALM+	Positive of opto-isolated alarm signal	The signal is effective (low voltage) when the driver is overcurrent, overheat.
	10	ALM-	Negative of opto-isolated alarm signal
	11	RDY+	Positive of opto-isolated ready signal	It is effective (low voltage) when the driver is ready for receiving controller’s signal.
	12	RDY-	Negative of opto-isolated ready signal
	13	24PU+	Positive of opto-isolated input signal	Drive voltage: +24V
	14	24DR+
	15	24MF+

Shenzhen DVS mechatronics co., ltd is a well-known company specializing in designing, producing and marketing motor drives and motors based on the most advanced technology in China. In 2014, we company was recognized as "national high-tech enterprise". Since DVS was founded in 2009, the inception --"to survive by quality and develop by service" has been uphold all the time. So we quickly occupied the automation industry market with excellent quality, competitive price and timely technical supports to our clients in just 6 years. Meanwhile our products are widely used in domestic market with a good reputation. Although there is quite a few companies copying and imitating our products, we are not caught up due to our advanced technology and professional equipments. Today there is tens of thousands of industries and OEM clients establishing long-term relationships of cooperation with us and becoming our loyal customers as well as treasured friends.
DVS offers a full complement of automation products with high quality including hybrid stepper motor drives & motors, AC servo drives & motors, easy servo systems (closed loop stepper). DVS has a strong R&D team consisting of 30 talents who possess at least 10 years relevant experience and high educated backgrounds in this field, which allows DVS to have capability of designing excellent motion controllers. Now all of DVS series of products have been successfully used in CNC machines, packing machines, textile machines, printing machines, engraving machine, labeling machines and etc. Moreover, Not only do we offer a wealth of industrial automation products but also provide clients with the most suitable selection scheme to help our customers to reduce their costs and enhance competitiveness in their industries. Because DVS believes that only we fully understand our customers and work closely with OEM clients can we be a successful motion product supplier. So in many cases, DVS experts and engineers themselves participate in the whole process of client product development, including initial application evaluation, product selection& suggestion.
DVS has been adhering to the "quality casts brand" business philosophy, and so the quality and performance of products are strictly controlled in accordance with international standards. Our production capacity can reach to 28,000pcs monthly. In order to reach requirements of stable and reliable performance, all products need not only to be checked with a routine inspection process but also a rigorous system of high temperature aging for a long time. The delay delivery always are a headache problem for most of buyers, Due to strong technical strength, superior production technology, advanced testing equipments , DVS can promise about 98% delivery on time.
