10. V/F curve: straight_line V/F curve,multi_point V/F curve,Square V/F curve

11. Ramp mode: straight_line ramp,S_curve ramp two groups of acceleration /deceleration time with the range of 0.00-300.0s(m)

12. DC braking: DC braking frequency:0.00Hz to maximum frequency ,braking time: 0.0-36.0s,braking action current value:0.0%-100.0%

13. JOG control: JOG frequency range: 0.00Hz to maximum frequency JOG acceleration/deceleration time 0.00-300.0s

14. Simple PLC,multi_speed running: it implements up to 16 speeds via the simple PLC function or combination of DI terminal states.

15. Built_in PID: it implements the closed_loop process control system easily.

16. Auto voltage regulation(AVR): it can keep constant of output voltage automatically when the mains voltage changes.

17. Over current stall control: the current is limited automatically during the running so as to avoid frequency tripping due to over current.

18. Rapid current limit: it decreases the over current faults to the minimum and ensures normal running of theAC drive.
