LC3522D Three-Phase 86/110 Digital Stepper Driver

Product Overview

LC3522D is a three-phase hybrid stepper motor driver based on DSP control, which combines advanced DSP control chips and threephase inverter drive modules to form a new generation of digital stepper motor drivers. The voltage is AC185~300V, which is compatible with various models three-phase hybrid stepper motors with a diameter of 86~110mm and a current below 7.0A. The driver uses a circuit similar too control principle inside, which makes the motor run smoothly and reduces noise a lot. The torque of the motor is much higher than that of the two-phase and five-phase stepper motors at high speed.

Features

Voltage input range: AC185V～300V Maximum peak current: 7.0A Subdivision range: 400～60000ppr Pulse form: Pulse + direction (dual pulse not supported) Pulse response frequency: 0～200KHz Phase memory function: when the pulse input stops for more than 3 seconds, the driver automatically memorizes the motor phase at that time
