Description
EN650 permanent magnet synchronous motor variable frequency drive adopts 32-bit DSP hardware platform to achieve large torque, high precision and broad speed range motor regulation. The VFD supports sensorless and sensor-aware vector control and has large low-frequency torque. The variable frequency drive is not sensitive towards motors’ parameters, nor is it reliant on changes of parameters. The VFD features strong stability against ambient temperature changes and quick and stable response upon high-speed halting.

Power range
380V three-phase: 5.5KW-55KW

Application
EN650 permanent magnet synchronous motor variable frequency drive is applied in refrigeration compressors, air compressors, new energy automobile motors, packing machinery and other industries.

Feature
1. Great low-frequency torque: EN650 permanent magnet synchronous motor variable frequency drive has the capability of outputting 150% working torque at 2.5Hz under open-loop vector mode.

2. High precision at steady state: EN650 permanent magnet synchronous motor variable frequency drive features a less than ±0.3% fluctuation from of output speed from input speed signals.

3. Rapid dynamic response: EN650 permanent magnet synchronous motor variable frequency drive supports rapid and stable response to high-speed halting, with acceleration/deceleration duration under maximum frequency reaching 0.1 second. The VFD manages to swiftly self-adapt and contain sudden load changes or instant acceleration/deceleration, so that overcurrent warning becomes a scarce case.

4. Excellent robustness: EN650 permanent magnet synchronous motor variable frequency drive is not sensitive towards motors’ parameters, nor is it reliant on changes of parameters. Consequently The VFD features strong stability against ambient temperature changes.

5. Convenient installing and tuning: EN650 permanent magnet synchronous motor variable frequency drive can automatically learn the internal motor parameters required for vector control. The standard configuration of the VFD contains a RS485 communication interface and supports Modbus and free protocol; Profibus, CanLink and CanOpen can be optionally configured and supported to fulfill all levels of net communication requirements of the bus. Multiple frequency levels are provided given channels and methods.
