7.5kw 11kw 15kw VFD 3 Phase 380V Variable Frequency Inverter AC Motor Drive
Features
Deceleration over excitation function
In many applications, the over-excitation function is set, the deceleration time is shortened by adjusting the motor output frequency and current, and the peripheral braking resistor and other accessories are reduced when the requirements for fast shutdown are met.
Energy saving function
It has excellent automatic energy saving function, only need to set the maximum energy saving target, as long as the operation meets
the energy saving condition, it can enter the automatic skill state.
By setting the VF function, it can realize the application of 1 drag and long distance control to meet the application of the transformation
occasion.
Undervoltage stall function
When the system is powered off instantaneously, the motor is controlled by the regenerative energy during deceleration to
maintain the inverter running for a short period of time and reduce the risk of idling under the instability of the grid.
User-Friendly Operation
Keyboard modes: standard mode (-bSC-), user defined mode (-USr-), check mode (-vrF-) and wizard mode (-GdE-), easy to switch.
Optional powerful LCD operator with parameter setting, parameter macro, monitoring, parameter copying, mobile phone Bluetooth, inverter program upgrade and other functions.
Excellent Speed Tracking
Non-impact smooth start for motors that do not stop rotating

Inverter Knowledge
1. How do you choose the right frequency inverter for your application?
When choosing a frequency inverter, factors to consider include the motor type and power rating, the application requirements for speed control and torque, the operating environment, and the desired level of functionality and communication options.
2. What is the difference between a frequency inverter and a soft starter?
A soft starter is a device that reduces the initial voltage supplied to a motor to limit the inrush current, while a frequency inverter provides variable speed control by adjusting the frequency of the power supplied to the motor.
