마이크로 스텝핑 바이폴라 스텝모터 드라이버로 조절가능한 전류 제한 기능, 1/32스텝까지의 7 microstep 분해능을 지원합니다.
실제 모터 전류를 모니터링하여 optimal decay mode는 동적으로 선택합니다.
모터에 낮은 부하가 걸려 있을 경우는 전력과 열을 덜 내기 위해서 동작전류를 자동으로 줄여 줄 수 있습니다.
10V-47V의 동작전압과 1.2A (per phase)를 방열판 없이 연속적으로 전달할 수 있습니다.
저전력, 과전류, 과열 보호 기능이 있습니다.
특징
Simple step and direction control interface
Seven different step modes: full-step, non-circular half-step, circular half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
Advanced Dynamic Mixed Decay (ADMD) dynamically switches between slow and fast decay modes by monitoring the state of current decay (not according to fixed timing)
Configurable Active Gain Control (AGC) automatically reduces drive current to minimize power consumption and heat generation when maximum torque is not needed
Motor supply voltage: 10 V to 47 V
Maximum continuous current per phase without additional cooling:
