This document introduces the iST57-10 integrated digital stepper motor from Shenzhen Leisai Intelligent Control Co., Ltd. The motor uses the latest dedicated motor control 32-bit DSP chip, which has high-speed performance, low heat generation, and low vibration, etc. It can improve the machining accuracy and speed of the machine and reduce energy consumption.
The Leisai iST57-10 is an integrated digital stepper system that combines a motor and driver using a 32-bit DSP chip. It features optical isolation, high pulse response frequencies up to 500KHz, and adjustable microstepping from 200 to 51200 pulses per revolution without requiring parameter tuning for optimal performance.
The document provides detailed instructions on electrical and mechanical specifications, including operating temperatures of -40°C to +80°C. It explains the driver interface definitions for power input (20-50V DC) and control signals (PUL, DIR, ENA), along with RS232 communication settings. Users can configure parameters such as current loop coefficients and microstepping via PC software or DIP switches. This manual is written in Chinese.
| Continuous Output Current | 0 - 6 A |
|---|---|
| Input Power Voltage | 20 to 50 Vdc |
| Pulse Frequency | 0 - 200 kHz |
| Operating Temperature | -40°C to +80°C |
| Microstepping Range | 200 - 51200 Pulse/r |
