Combined drive

Compatible with multiple motors
Vector drive for asynchronous AC induction motors and permanent magnet synchronous motors. Reduce the inventory effectively without considering the motor compatibility.
* The traditional permanent magnet synchronous motor includes SPM and IPM.
* The variable frequency mptor includes high speed spindle.

More accurate motor autotuning
Correct rotating and static motor autotuning. Convenient debugging, easy operation.
- Rotating autotuning: need separate motor from the load, applied to the situation with high control accuracy.
- Static autotuning: no need to separate motor from the load, applied when rotating autotuning is not available.

Optimized SVPWM control
The current, torque and rotating speed waveforms when sudden loading or unloading is asynchronous motor SVPWM control mode with 2Hz running frequency and full load.



Advanced open loop vector control
- Asynchronous motor



The current, torque and rotating speed waveforms when sudden loading or unloading in asynchronous motor open loop vector control mode with 0,25Hz running frequency and full load.



- Synchronous motor



The current, torque and rotating speed waveforms when sudden loading or unloading in synchronous motor open loop vector control mode with 3Hz running frequency and full load.



Torque control mode (open loop)
The current, torque and rotating speed waveforms when sudden loading or unloading in asynchronous motor torque control mode with full load.



The FWD/REV current, torque and rotating speed waveforms in synchronous motor torque control mode with 100Hz running frequency and full load.



More smoother and more quieter running by applying advanced 3-phase modulation



Excellent performance on specific motors such as high speed spindle, direct-control motor
The current waveforms in synchronous motor open loop vector control mode with 300Hz running frequency and full load.



Multiple braking modes and instant stopping
- Dynamic braking
Configure braking units and resistors . Available on the situation of big inertia load and frequent braking. Big braking torque and quick braking.
- DC braking
No need to configure braking units and resistors. Available on the situation when start the running motor after braking and the situation when keep the moment output after braking to zero speed. Not available on the situation of big inertia load or instant stopping braking in high speed running.
- Flux braking
No need to configure braking units and resistors. Available on the instant stopping situation with big inertia load and no frequent braking. Not available on the situation of big inertia load and frequent and braking (the energy consumed on the stator and its cooling is better than DC braking).
- Short circuit braking
No need to configure braking units and resistors, capable of braking quickly. Applicable to the motors at quick start and stop or restart after braking. Not applicable to big inertia load and frequent braking.

Perfect voltage and current control, reducing the fault protection times
- OV fault:
Adjust the output frequency to avoid overvoltage of the DC bus during deceleration
- OC fault:
Adjust the output frequency to avoid overcurrent of the VFD during acceleration.

Continuous running in instantaneous power off
The VFD can keep running if the grid voltage drops and used in the situation with high requirement such as fiber and textile production line.

Multi-function with simple operation

Separate air-duct
The separate air duct prevents the contaminants into the electronic parts/components and greatly improves the protective effect of the VFD, as well as its reliability and service life, to adapt various complicated site environments. It can also facilitate the heat-releasing in control cabinets and the heat-releasing design of the customer.

Multiple installation modes
Wall, flange and floor installation.

Book structure
Parallel installation. Little installation space with less cost and beautiful appearance.

C3 input filters (standard) and C2 filters (optional)
C3 input filter is embedded in the factory to meet different application requirements, save installation space and avoid the electromagnetic interface caused by incorrect selection and site installation.

Abundant I/O terminals



Smaller size
Due to the thermal simulation and advanced modularized design, the size of the product is reduced greatly.

High performance keypad
The standard LED keypad supports parameters upload and download with maximum length of 200m and digital potentiometer. The optional external LCD keypad supports parameters loading and unloading with displaying 10 lines and 10 rows of Chinese characters and several languages.

Embedded braking units of 1.5-30 kW VFDs
Reduce the occupied space and dynamic braking is available if install corresponding braking resistors.



Heavy-load design



Various application functions
- V/F separation setting:
Meet the requirement of different power supplied and realized flexible setting of V/F curve.
- Two groups of motor parameters:
Different motors can use the same VFD, reducing the cost, shifting between two motors making electrical control more convenient.
- Virtual terminal function:
Make the middle variables as the local virtual I/O quantity, save the hardware configuration.
- Speed tracking:
Available on asynchronous motor and permanent magnet synchronous motor and the situation of big inertia load, reversal rotating during starting and continuous frequent shifting.
- Digital signal, high speed pulse and relay:
Provide more programmable and control modes.
- Electric power display:
Display the total consumed energy. No need to use the power meter.
- Stop delay:
Ensure the motor stop safely under control.
