1. Overview
The core control unit of the series digital DC (reversible
/
irreversible) speed regulating device adopts the British Continental
series, Siemens
series and other all-in-one series. Digital DC speed control device, the system is used for armature and excitation power supply of adjustable speed DC motors. It can automatically adjust the motor to operate at constant torque below the rated speed and at constant power above the rated speed. The control system is divided into two types: reversible and irreversible. The irreversible control system is used when the motor only needs to be controlled to rotate in one direction or does not need to frequently start the motor to rotate forward and reverse. The reversible control system is used when the motor is required to control the motor to rotate quickly forward and reverse or brake quickly. , parking and frequent reciprocating motion, potential energy conversion and other production machinery that require four-quadrant operation, and the motor can be used to obtain the best dynamic response and steady-state accuracy. The speed control cabinet has fault prompts and protection measures such as overcurrent, overload, loss of excitation, and phase loss, ensuring the normal operation of the system within the set range.

3. Performance parameters
The core control unit of the speed control system has compact hardware structure and software Rich in functions, the system has double closed-loop
regulation of speed and current and online self-tuning of parameters. The current loop sampling time is less than
the non-circulation time when the device torque is reversed. The factory setting is
so that the current The loop has excellent dynamic performance against impact loads, and the current loop adaptive function ensures that the system can obtain a smooth speed response even when the load changes greatly.
