Closed Loop Stepper Driver 0~8.2A 18~70VDC for Nema 34 Stepper Motor

Closed Loop Stepper Driver 0~8.2A 24~100VDC for Nema 34 Stepper Motor

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 (800-51200) to meet the requirements of most customers;
It has several protection functions such as overcurrent, overvoltage, overspeed, overheating, and excessive tracking error.
