The MD310 series is a general-purpose compact AC drive adopting sensorless vector control and V/f control. It is used for asynchronous motor control with the high-performance current vector control technology. The MD310 supports Modbus RTU communication through its standard RS485 port. It can be expanded with an I/O expansion card or CAN communication expansion card. Its built-in PID helps implement a closed-loop process control system and supports up to 16 operation speed references.
