1. PI9000 could control both Asynchronous motor and Synchronous motor (permanent magnetic Synchronous motor)
2. Performance of V/F control mode, speed sensor-less vector control mode (open loop), speed sensor vector control mode (closed loop with PG) are much better compares with PI8000 and PI7800 series products, motor efficiency has been improved by 3%-5%, provides effective energy saving scheme for motor system.
3. Speed sensor-less (open loop) torque response time: 20ms, 150% torque output at 0.5Hz
4. Speed sensor (closed loop with PG) torque response time: 5ms, 100% torque output at 0Hz
5. Temperature rise test have been tested all qualified
6. Motor parameter self learning
