This document describes the instructions for using the AMDP-X/E21□ series motor protectors from Shenyang Xinwei Automation Co., Ltd. The protectors feature digital setting, digital display, complete protection functions, reliable protection performance, zero-sequence current detection, etc. They are suitable for three-phase AC motors with a voltage not exceeding 1140V and a frequency of 50Hz or 60Hz.
The XWAM AMDP‑X/E21 series motor protector provides comprehensive protection for three‑phase AC motors up to 1140 V. It uses a DSP core, offers digital setting and display, and includes protection functions such as phase loss, short‑circuit, ground fault, stall, overload, current imbalance and zero‑sequence detection.
The manual explains the LED display, keyboard operation, parameter configuration, zero‑sequence protection, RS‑485/MODBUS communication, fault codes, wiring diagrams and installation dimensions, enabling users to set up and maintain the device safely. This manual is written in Chinese.

Press the R key; this resets the microcontroller and stops the motor.
Fault code EE01 means a ground fault has been detected.
Up to 32 protectors can be connected on a single RS‑485 segment.
Set parameter E4 to 1; this selects MODBUS communication.
