Closed Loop Stepper Driver 0~6A 24~100VDC OK2D86BH(With Radiator and Fan) for Nema 34 Stepper Motor
This Closed-loop Stepper driver offers an alternative for applications requiring high performance and high reliability when the servo was the only choice, while it remains cost-effective. The system includes a 2-phase stepper motor combined with a fully digital, high performance drive and an internal encoder which is used to close the position, velocity and current loops in real time, just like servo systems. It combines servo and stepper motor technologies, and delivers unique capabilities and enhancements over both, while at a fraction of the cost of a servo system.
Key Features:
Closed-loop, eliminates loss of synchronization
Broader operating range - higher torque and higher speed
Reduced motor heating and more efficient
Do not need a high torque margin
No Tuning and always stable
Quick response, no delay and almost no settle time
High torque at starting and low speed, high stiffness at standstill
Offer servo-like performance at a much lower cost;
Performance parameters:
Adopting new 32-bit motor control dedicated dual-core DSP chip;
Adopting advanced vector current and speed and position closed-loop control algorithms;
The static current and dynamic current ratio can be automatically set;
The motor comes with a 1000-line high-precision encoder;
Optocoupler isolated differential signal input;
The impulse response frequency can reach up to 300KHZ;
Subdivided into 16 settings (800-40000) to meet the requirements of most customers;
It has several protection functions such as overcurrent, overvoltage, overspeed, overheating, and excessive tracking error.
