Product Introduction:Dual mode 2 Phase Digital Microstep open loop Stepper Drive for nema 17 motor's current under 3A
ECON provides tens of models of stepper drives. From 2 phase to 3 phase, DSP digital, 24--80 DC input or 24--80VAC input, and can provide the right stepper drives to satisfy the special needs of your stepper control systems. ECON’s stepper products are well-known because of their wide choices, excellent performance, easy to use, high reliability, and low cost. The stepper drives have been used by thousands of OEM clients in the world from many of industries such as CNC machinery, medical, electronics, semiconductor, packaging, lab automation.
The high performance EO series digital stepper drives are featured with extra low noise, very low motor heating, and ultra smooth motor movements at low speed. With performance and cost balanced.
EO430 is the new generation high performance fully digital stepper drive which base on 32bit DSP with a advanced algorithm .the power supply range is DC12~32V. it can drive 2 phase nema17 stepper motor .
Ultra low noise and high smoothness at middle/low speed ,and high torque at high speed, which can be applied to different speed control applications. adopt smooth and accurate sinusoidal current vector control technology ,which make motor low heat .
Product Features:
1.Voltage:12V~32VDC,peak current 3A
2.Apply for magnetic linkage vector resonance resistance algorithm and electronic damping low-speed vibration arithmetic
3.Auto recognize motor parameters and auto tuning control parameters when power is on
4.Build-in micro-step segmentation algorithm, to achieve low segmentation control command, high segmentation operate effect
5.Receive differential and single-end PUL/DIR command
6.Pulse,direction,enable signal port level compatible 4.5V~28VDC ,no need to connect external resistor
7.Set positive edge ,negative edge and motor default direction by serial port
8.Control command Max pulse frequency is 500KHz(Default is 160KHz)
9.Provide 16 gears micro-step subdivision value setting, to set 200~51200 any subdivision by Serial port
10.Have RS-232,can set or change drive parameters
11.Reliable,signal port is optical isolation
12. Over-voltage,over-current,under-voltage protecting
Applications:
It can be used in various kinds of machines ,such as dispenser machine, floating machine, 3D printer, labelling machine, medical machine, laser cut machine, and so on ,its unique features make it an ideal solution for the applications which require low noise ,low vibration, low heat and high precision
