1. Overview:

750W BLDCM driver is a high-power driver independently developed by lanjiu company to cooperate with the field of modern industrial automatic control. It mainly uses foreign high-performance special-purpose BLDCM driver chip, which has a series of advantages such as high integration, small size, perfect protection, simple and clear wiring, high reliability, etc. The driver is suitable for driving large and medium-sized BLDCM with rated power below 750W. The driver adopts a new PWM technology, which makes the BLDCM run at a high speed, with small vibration, low noise, good stability and high reliability. Support Modbus communication protocol and RS485 interface.

3. Installation precautions

*It is forbidden to open the shell for measurement or touch any device and connector on the bottom plate during operation.

*Check the bottom plate or replace the fuse tube 1 minute after power failure.

*During operation, it is forbidden to operate the drive without enclosure.

*The driver and motor of the brush less motor shall be well and reliably grounded, otherwise the speed of the motor may be unstable.

*If the drive is accidentally damaged during operation, the company is only responsible for the maintenance and replacement of the drive within the scope of warranty. The company will not be liable for motor out of control or personal injury and property loss caused by accidental damage to the drive.

III. installation dimension: 165 * 67 * 102mm

4. Means of communication:

The communication mode adopts standard Modbus protocol, which conforms to the national standard GB / T 19582.1-2008. Two 3-core Phoenix terminals with a distance of 3.81mm are used for the physical interface. The serial connection is very convenient. Transmission mode RTU, validation mode CRC, CRC start word ffffh. Data mode 8-bit asynchronous serial, 2-stop bit, invalid check bit, supporting multiple communication rates (see parameter table for details).

Note: if it is necessary to control the motor in communication mode, it must be carried out in internal speed regulation mode.
