Product catalog summary

Product Information

Model Specification: The ST300 series offers models with power grades from 0.75 kW to 2.2 kW, detailing output/input current and adaptive motor power.
Technical Data: Specifications include power grade, output/input current, and adaptive motor power for each model.

Function Code Parameter List

Motor Parameters: Covers motor rated frequency, speed, number of motors, and self-tuning options, with model-dependent parameters like stator/rotor resistance and no-load current.
Input Terminal Selection: Assignable functions include operation modes, fault inputs, and frequency settings.
PLC Operation Mode: Simple PLC settings for power failure memory, time unit selection, and stage operation frequency.
PID Parameters: Settings for PID channels, feedback, adjustment options, and filtering times, with adjustable proportional gain, integral, and differential times.
System Control: Parameters for locking functions, STOP button, and keyboard M key functions.
System Protection: Options for fan control, automatic fault reset, and overload alarm detection.
Enhanced Functions: Carrier frequency settings and energy braking options.

Overview: The document from Guangdong Dingshen Electric Technology Co., Ltd. details function code parameters and fault countermeasures for their electric technology products, including specifications, status parameters, fault records, and exception handling procedures.

Specifications and Parameters:

Voltage and Current Parameters: Specifies voltage/current parameters, including overpressure and overvoltage stall options, with operational values and conditions.
Status Parameters: The U00 group includes parameters for analog input status, switch input/output status, machine status, PID settings, bus voltage, output voltage/current, power, torque, temperature, and more, each with a specific code and value range.

Fault Records and Handling:

Fault Types: The U01 group records faults like module protection failure, current detection fault, overvoltage, overheating, overload, undervoltage, phase loss, etc., each with a numeric code.
Fault Countermeasures: Chapter 3 outlines countermeasures for each fault type, including checking connections, adjusting settings, seeking technical support, and replacing faulty components, with specific causes and solutions for each fault code.

Software and Production Information:

Software Version: The U02 group lists product series, software versions, rated power, voltage, current, and production details.

Key Recommendations:

Ensure proper parameter settings and regular maintenance to prevent faults.
Follow specified procedures for fault handling and seek professional support when necessary.
Regularly update software and check compatibility with hardware components.

Specifications and Procedures:
The document outlines the communication protocol for the ST300 series inverter by Guangdong Dingshen Electric Technology Co., Ltd., using a single RS485 communication interface with the MODBUS protocol for operations like reading/writing function parameters and control commands. The inverter operates in slave mode during communication.

Transport Details:
The RS485 interface is asynchronous, half-duplex, with high bytes first and low bytes last. The factory default format and baud rate are 1-8-1-N, 9600bps.

Address Correspondence and Function Definition:
Includes a register distribution for the frequency converter, detailing control parameters not saved during power failure, such as control command word, principal frequency setting, electric torque limit, and regenerative torque limit.

Control Command Word Definitions:
Defines operational states like running command validity, forward/reverse turn, deceleration, emergency shutdown, and fault reset.

Special Instructions:
Data frames in ASCII format with even frame lengths are discarded. Avoid multiple multi-function input terminals with the same settings to prevent functional disorder. Parameters with negative values are handled uniquely, with specific data read values for negative inputs.

Contact Information:
Operational Address: No. 118, Liangle Road, Gujian Village, Daliang Street, Foshan, Guangdong, China. Telephone: 0757-22613860, Fax: 0757-22613860.
