V/F curve (volt. frequency
characteristic)
Set rating frequency randomly at range of
5~400Hz，can choose constant torque, degressive
torque 1, degressive torque 2, degressive torque 3
and user-defined V/F in total 5 kinds of curve
Accelerating decelerating curve

brake
Interior or exterior brake resistance. 690 V grade
haven’t build-in brake unit .
DC brake
Optional start-up and stop，action frequency 0~15Hz，
action volt. 0~15%，action time 0~20.0 s
Jog
Jog frequency range: 0.50Hz~50.00Hz; jog
accelerating decelerating time 0.1~60.0s can be set
Multisection speed running Realized by interior PLC or control terminal
Interior PID controller Be convenient to make closed-loop system
Automatic energy save running
Optimize V/F curve automatically based on the load
to realize power save running
Automatic volt. regulation
(AVR)
Can keep constant output volt. When power source
voltage varies.
Automatic current limiting
Limit running current automatically to avoid
frequent over-current which will cause trip
