Features: 1. Adopt advanced 32-bit special motor control digital signal processing chip and vector close-loop control technology. 2. Step-and-loop close-loop circuit system can improve motor output the moment of force and speed without losing motion synchronization. 3. Adjust the current according to the load to reduce the motor temperature rise. 4. Suitable for various mechanical load conditions (including low rigidity pulleys and pulleys) without adjusting the gain parameters. 5. The motor runs smoothly and the vibration is slight, which improves the dynamic performance of acceleration and deceleration. 6. 0 speed static capability without vibration after positioning is completed. 7. Support over current protecting, over voltage protecting, position over tolerance protecting. 8. Built-in position and alarm output signals for easy PC monitoring and control. 9. The position tolerance alarm function guarantees safe operation of the processing equipment.
