Description

technical field [0001] The invention belongs to the field of industrial control, and in particular relates to a low-voltage AC servo motor driving device. Background technique [0002] With the development of automated production technology, many servos and servo drives are used in motion control systems, and in some occasions, the real-time requirements for multiple servo movements are high. Existing servo drives generally use RS-485 and CAN bus for communication. The transmission speed is slow and the data transmitted is small, and it is difficult to meet the occasions where multiple servos and servo drives are used and high real-time performance is required. [0003] In order to meet the servo drive voltage requirements and provide suitable voltage for the control part, most of the existing drivers need to perform voltage conversion. The voltage conversion circuit not only occupies a large space of the driver, but also causes power loss during the conversion process. Mos...

Existing servo drives generally use RS-485 and CAN bus for communication, the transmission speed is slow and the transmitted data is small, it is difficult to meet the occasions where multiple servos and servo drives are used and high real-time performance is required

[0003] In order to meet the servo drive voltage requirements and provide a suitable voltage for the control part, most existing drives need to perform voltage conversion. The voltage conversion circuit not only occupies a large space of the drive, but also causes power loss during the conversion process.

Most existing drives need to add additional circuits to solve the problem that the kinetic energy generated when the motor brakes is converted into electrical energy that affects the drive
