Features: Technical Specifications: The controller features three frequency signals: High (5.4kHz to 160kHz), Mediumed (540 Hz to 16kHz), and Low (80Hz to 2.4kHz). User-Friendly: This straightforward configuration—controller + stepper driver + stepper motor + power supply—forms a simple control platform. Highly Performances: Capable of generating pulses signals and adjustment signals, with selectable skip functionality. Frequency Measurement: Measurement is possible via both the PUL port and the common (or common anode) port. High Practicality: This module functions as a pulses generator, conveniently providing the stepper driver as the . Usage Note: A driver must be fitted to control the stepper motor. Specifications: Product type: Stepper motor drive control Component: Plastic Size: Approximately 38.6x58mm/1.5x2.3inches. Different stepper motor driver have different labels, but the functions are the same: EN=ENA=enabled.. DIR=CW=CWW Direction Connection of common anode (connector B). Package Includes: 1PC Host module 2PCS Connection cable (red and black, 20cm long) 1PC Chinese and English bilingual instruction manual note: Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution.
