MD310 series inverter is a general-purpose compact multifunctional inverter, which adopts open-loop vector and V/F control, and can realise asynchronous motor control with high-performance current vector control technology.MD310 is equipped with RS485 communication interface as standard, and supports Modbus RTU communication, and can be expanded with I/O expansion card and CAN communication expansion card.The built-in PID can easily realise closed-loop process control system, and it can realise up to 16-segment speed operation.
