Core Control & Software Functions
- Unified Motor Control: Smoothly drives three-phase AC induction motors, permanent magnet (PM) synchronous motors, and synchronous reluctance motors.
- Advanced Control Modes: Employs Open-loop V/F control, Sensorless Vector Control (SVC), and high-precision Closed-loop Vector Control (FVC).
- Application-Specific Logic: Features a built-in textile wobble control function and Master-Slave load-sharing control (torque and speed).
- Dynamic S-Ramps: Uses 4 independent programmable S-ramps for smooth, jerk-free mechanical acceleration and deceleration.
- Brake Logic Control: Integrated safety logic sequences for safe external mechanical brake release and engagement.
- DC-Injection Braking: Variable DC injection stops motors rapidly without locking mechanisms.
- Multi-Motor Switching: Houses 4 completely independent sets of internal motor parameters to swap control between different motors. [1, 2, 3, 4]
