IC697CHS790 Fully Digitally Powered DC Motor Driver

IC697CHS790 clamp type crane is used to lift hot and cold steel billets above the equalizing furnace, which has high temperature, metal dust, heavy load and high vibration. Therefore, the high requirements for electronic control equipment, we chose the British Control Techniques (CT) company’s Mentor II all-digital DC speed control device, which uses a microprocessor core, operating instructions and operating parameters can be input from the panel or serial port, set and modify, and protected by the three levels of confidentiality word protection.

All analog inputs and most digital inputs of the IC697CHS790 are user programmable. Serial port RS485, easy to multi-machine networking, and the host computer and other equipment to form an automation network, but also provides a variety of options to enhance system functionality, such as magnetic field control module with automatic weak magnetism for constant power application of weak magnetism control, BASIC language programming MCU processing module and intelligent multi-text user interface, etc., compact structure, high reliability.

IC697CHS790 is a fully digital DC motor driver M550R from Control Techniques (UK), with an output current range of 25 A to 1850 A. It is divided into two configurations: single-quadrant and four-quadrant. The single-quadrant drive is capable of forward operation only, while the four-quadrant drive is fully reversible. Both configurations of the drive can fully control the speed and torque of the motor, and the four-quadrant drive can fully control forward and reverse operation. It still works on the basic principle of controlling the terminal voltage of the armature and thus the current fed to the motor, thus achieving speed regulation.
