MD310 Compact Multifunction Variable-Frequency Drives MD310T15B
The MD310 series is a compact, general-purpose multifunction variable-frequency drive using open-loop vector and V/F control. High-performance current-vector control drives asynchronous motors. The MD310 standard RS485 interface supports Modbus RTU, with optional I/O and CAN communication expansion cards. Integrated PID simplifies closed-loop process control, with up to 16 speed stages. Applications include drives for textiles, papermaking, wire drawing, machine tools, packaging, food processing, fans, pumps and automated production equipment.

Key Features
Compact size: space-saving structure supports side-by-side mounting Overexcitation: suppresses DC-bus voltage rise during deceleration to avoid frequent overvoltage faults Control applications: integrated PID and selectable frequency-reference channels simplify automatic process control, including constant temperature, pressure and tension Traverse-frequency function: improves uniform, flat and dense spindle winding in textile and chemical-fiber equipment Time-sharing control: stores 4 motor-parameter sets so one drive can operate four motors at different times Timed operation: run time set through parameters or analog signals Fast bus connection: standard RS485 with Modbus RTU and optional CANLink for fast bus connections with Huichuan products Virtual oscilloscope: supports drive-parameter operations and graphical monitoring of internal drive status Standard braking unit: connects directly to a braking resistor without an external braking unit, reducing cost
