3. Working Principle

Equipment Initialization & Parameter Setting

After power-on, the auxiliary power supply generates required voltage for control circuits from DC bus and completes self-check and initialization. Operators can set rated motor current, PI parameters, command input range and other parameters via PCB adjustment ports according to motor characteristics and actual working conditions.

Command & Feedback Collection

±10V analog commands transmitted from upper controllers are sent to the control unit through differential input interfaces. Meanwhile, real-time RLG/tachometer feedback signals from motors are filtered and amplified by detection units to collect accurate motor speed and position data.

PI Closed-loop Regulation & PWM Output

The control unit compares command signals with actual speed feedback, calculates error adjustment values through PI controller and generates three-phase trapezoidal commutation PWM signals. These signals drive the power output stage (three-phase transistor bridge) to output adjustable three-phase AC power, so as to regulate motor speed and torque in real time and realize stable four-quadrant operation.

Fault Monitoring & Protection

During operation, the device monitors output current, bus voltage and insulation status continuously. Once faults such as short circuit, earth fault and overcurrent are detected, it will cut off power output immediately and send out fault feedback signals to protect the drive and motor and prevent fault escalation.
