Simple PLC, 
multiple speeds
It realizes up to 16 speeds via the built-in PLC function or combination of 
DI terminal states.
Built-in PIDIt realizes closed loop control system easily.
Auto voltage 
regulation (AVR)
It can keep constant output voltage automatically when the power grid 
voltage fluctuates.
Overvoltage/ Over 
current stall control
The current and voltage are limited automatically during the running process
 so as to avoid frequently tripping due to overvoltage / over current.
Rapid current 
limit function
It can protect the proper running of the inverter, and furthest avoid the 
over-current faults.
Torque limit and control(Excavator characteristics) It can limit the torque automatically and prevent
 frequently over current tripping during the running process.
Torque control can be implemented in the VC mode.
Individualized
 functions
High performanceControl of asynchronous motor is implemented through the high performance 
current vector control technology.
Instant power off 
not stop
The load feedback energy compensates the voltage reduction so that the
 frequency inverter can continue to run for a short time.
Rapid current limitTo avoid frequently over current faults of the frequency inverter.
Virtual I/OsFive groups of virtual DI/DO can realize simple logic control.
Timing controlTime range: 0.0~6500.0 minutes
Multi-motor switchoverTwo motors can be switched by two groups of motor parameters.
Multiple communication 
protocols
It supports RS-485 Modbus.
Advanced background 
software
It supports the operation of frequency inverter parameters and virtual os
cillograph function, by which the state of frequency inverter can be monitored.
