This manual covers the JMDM-COMTSM, a driverless two-axis motion controller for stepper motors with RS232/RS485 communication and built-in drive circuitry.
The JMDM-COMTSM is an industrial-grade, programmable, and monitorable two-axis motion controller developed by Shenzhen Jingmin Digital Machine Co., Ltd. It features a driverless design that can directly drive 57 or smaller stepper motors with a maximum phase current of 2A, eliminating the need for external drivers.
The device supports both independent control via embedded C programming (Keil) and remote monitoring/control via PC serial communication. Key specifications include 8 high-speed digital inputs, 3 digital outputs, and 2 pulse output channels capable of up to 400KHz. It utilizes an intelligent S-curve acceleration/deceleration algorithm for smooth motor control. This manual is written in Chinese.
