Product Introduction The Emm28_V5.0 closed-loop control module is a newly launched upgrade version by Zhang Datou Closed-Loop Servo, based on the Emm42_V4.2. It features an upgraded closed-loop algorithm and integrates the ZDT_X28_V1.3 software and hardware framework. This enhancement delivers higher rotational speed, faster printing speed, and more powerful functionalities. Additionally, it supports built-in serial port/RS232/RS485/CAN bus modules and motor stall current limiting, offering greater safety and reliability. It meets the needs of a wider range of users and is suitable for applications such as 3D printing, writing machines, engraving machines, PLC control, robotic arms, and car competitions.

Product Features
1.Emm28_V5.0 adopts an advanced FOC vector closed-loop control algorithm, achieving triple-loop control (torque, speed, and position).
2.Features an onboard industrial-grade high-precision 16384-line magnetic encoder, onboard precision current sensors, and an onboard dual H-bridge composed of 8 high-quality MOSFETs rated above 30A.
3.Maximum current 3000mA, maximum speed 3000RPM+ (the maximum speed may vary depending on individual motor parameters).
4.Supports pulse control, serial/RS232/RS485/CAN communication control, and hybrid control combining both methods;
5.Supports Modbus-RTU protocol and custom protocols.
6.Supports multi-unit communication and synchronous control, allowing communication and synchronized control for up to 255 addressable motors.
7.Supports speed mode and position mode control, supports S-curve acceleration/deceleration, supports immediate stop. Each position command supports both absolute and relative positioning modes.
8.Open-loop mode also supports communication control, with a maximum speed of 200-400RPM, and also supports S-curve acceleration/deceleration and synchronous control.
9.Supports a speed as low as 0.1RPM, supports storing direction, speed, and acceleration parameters for automatic operation upon power-up, and IO control for start/stop.
10.Supports single-turn shortest-path homing, single-turn directional homing, multi-turn limitless collision homing, and multi-turn finite limit switch homing.
11.Supports communication-controlled in-position output/in-position return command, and supports pulse control alarm output.
12.Supports left/right limit switch input; motor movement is prohibited beyond the triggered limit direction.
13.Supports real-time display and reading of RPM, phase current (mA), and bus voltage (mV).
14.Features stall protection with configurable detection current, speed, and duration; stall protection can be cleared via command without requiring a power cycle.
15.Supports both common-anode and common-cathode signal input, compatible with 24V PLC signal input; opto-isolated input is optional.
16.Inherits the ZDT_X42_V1.2 hardware platform, supports built-in serial/RS232/RS485/CAN bus modules.
17.Supports 1-256 arbitrary microstepping with interpolation function, enabling smoother and quieter motor operation.
18.Onboard small screen displays system information in real time; onboard keys allow one-touch parameter modification with automatic save and immediate effect.
19.Motor speed and position are updated in real time (even when not enabled), and can be cleared via command.
